pour une mise à jour de la cartographie avec les ajouts de nombreux contributeurs, voir ce dépôt GitHub:
https://github.com/samuelneff/MimeTypeMap
j'ai trouvé de nombreux types mime que mon application utilise ne sont pas dans le registre Windows par défaut et d'autres sont dans le registre, mais pas dans la liste incluse avec IIS. J'ai compilé une liste de ces emplacements et quelques autres que nous utilisons.
EDIT: Voir plus haut-ne-date de la version avec les contributions ici , y compris un moyen efficace et déterministe les deux sens de la cartographie.
private static IDictionary<string, string> _mappings = new Dictionary<string, string>(StringComparer.InvariantCultureIgnoreCase) {
#region Big freaking list of mime types
// combination of values from Windows 7 Registry and
// from C:\Windows\System32\inetsrv\config\applicationHost.config
// some added, including .7z and .dat

pour ASP.NET ou autre
les options ont été changées un peu dans ASP.NET Core, les voici ( crédits ):
-
new FileExtensionContentTypeProvider().TryGetContentType(fileName, out contentType);(vNext seulement)- jamais testé, mais on dirait que vous pouvez officiellement étendre la liste des types mime via la propriété
Mappingsexposée.
- jamais testé, mais on dirait que vous pouvez officiellement étendre la liste des types mime via la propriété
- utiliser le
MimeTypesNuGet package - copier le fichier
MimeMappingsà partir de la source de référence du .net Framework
for. NET Framework >= 4.5:
utilisez la méthode System.Web.MimeMapping.GetMimeMapping , qui fait partie de la BCL dans .net Framework 4.5:
string mimeType = MimeMapping.GetMimeMapping(fileName);
si vous avez besoin d'ajouter des mappages personnalisés, vous pouvez probablement utiliser la réflexion pour ajouter des mappages à la BCL MimeMapping classe, il utilise un dictionnaire personnalisé qui expose cette méthode, donc vous devriez invoquer ce qui suit pour ajouter des mappings (jamais testé tho, mais devrait prob. travail.)
quoi qu'il en soit, lorsque vous utilisez la réflexion pour ajouter des types MIME, soyez conscient que puisque vous accédez à un champ privé, son nom pourrait changer ou même être totalement supprimé, donc vous devriez être extrêmement prudent et ajouter des doubles vérifications et fournir une action de sécurité d'Échec pour chaque étape.

vous pouvez utiliser cette fonction helper:
private string GetMimeType (string fileName)
{
string mimeType = "application/unknown";
string ext = System.IO.Path.GetExtension(fileName).ToLower();
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (regKey != null && regKey.GetValue("Content Type") != null)
mimeType = regKey.GetValue("Content Type").ToString();
return mimeType;
}

Juste pour faire Shimmy 's réponse plus clair:
var mimeType = MimeMapping.GetMimeMapping(fileName);
système.Web.dll v4.5
// Summary:
// Returns the MIME mapping for the specified file name.
//
// Parameters:
// fileName:
// The file name that is used to determine the MIME type.
public static string GetMimeMapping(string fileName);

Vous pouvez trouver cette information dans le registre. Par exemple, le type MIME pour .le fichier pdf peut être trouvé dans la clé HKEY_CLASSES_ROOT\.pdf , dans la valeur "Type de contenu":
string mimeType = Registry.GetValue(@"HKEY_CLASSES_ROOT\.pdf", "Content Type", null) as string;

j'ai écrit un programme pour récupérer et convertir le mime Apache .les types de fichier C# Dictionary<string, string> identifié par l'extension de fichier. C'est ici .
la sortie réelle est ce fichier (mais vous pourriez vouloir le saisir et l'exécuter à nouveau au cas où le fichier Apache a été mis à jour depuis la dernière fois que j'ai lancé ce fichier).
public static Dictionary<string, string> MimeTypes = new Dictionary<string, string>

j'aime le travail que Samuel Neff fait, mais pas de l'idée et de surcharge de la création d'un dictionnaire à chaque fois.
j'ai restructuré les choses comme un interrupteur. Oui, vous ne pouvez pas itérer sur elle, mais dans mon cas, je ne l'utilise que pour trouver rapidement une valeur. Surtout parce qu'il est fait dans un service web, la dernière chose que je veux est un tas de frais généraux que l'application prépare ses structures. Le compilateur transformera cela en une recherche hachée et ce sera donc très rapide.

inspiré par la réponse de Samuel, j'ai écrit une version améliorée:
- fonctionne également lorsque l'extension est en majuscule.
- prend nom de fichier comme entrée, gère les fichiers sans extensions avec élégance.
- N'inclut pas"."dans les touches.
- Liste de Apache , pour lequel j'ai écrit un la petite transformation de script .
le le code source résultant est plus de 30k caractères donc je ne peux pas le poster ici, Vérifiez sur Github .

, Vous pouvez utiliser le tableau de Apache httpd. Il devrait être trivial de mapper ceci dans une fonction, un dictionnaire, une liste, etc.
aussi, comme vu ici , extension->type mime n'est pas nécessairement une fonction. Il peut y avoir plusieurs types MIME courants par extension de fichier, de sorte que vous devriez examiner les exigences de votre application, et voir pourquoi vous vous souciez des types MIME, ce que vous voulez "faire" avec eux, etc. Pouvez-vous utiliser des extensions de fichier pour avoir le même comportement? Avez-vous besoin de lire les premiers octets d'un fichier pour déterminer son type MIME ainsi?

pour rendre le post plus complet, pour .net Core devs il y a FileExtensionContentTypeProvider classe, qui couvre le Officiel MIME types de contenu .
il fonctionne derrière la scène - définit ContentType dans les en-têtes de réponse Http basés sur l'extension de nom de fichier.
dans le cas où vous avez besoin de types MIME Spéciaux, voir exemple sur la personnalisation des types MIME :
public void Configure(IApplicationBuilder app)
{
// Set up custom content types -associating file extension to MIME type
var provider = new FileExtensionContentTypeProvider();
// Add new mappings
provider.Mappings[".myapp"] = "application/x-msdownload";
provider.Mappings[".htm3"] = "text/html";
provider.Mappings[".image"] = "image/png";
// Replace an existing mapping
provider.Mappings[".rtf"] = "application/x-msdownload";
// Remove MP4 videos.
provider.Mappings.Remove(".mp4");
app.UseStaticFiles(new StaticFileOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "images")),
RequestPath = new PathString("/MyImages"),
ContentTypeProvider = provider
});
app.UseDirectoryBrowser(new DirectoryBrowserOptions()
{
FileProvider = new PhysicalFileProvider(
Path.Combine(Directory.GetCurrentDirectory(), @"wwwroot", "images")),
RequestPath = new PathString("/MyImages")
});
}

la plupart des solutions fonctionnent, mais pourquoi prendre des efforts alors que nous pouvons aussi obtenir le type mime très facilement. Dans Le Système.Web assembly, il y a une méthode pour obtenir le type mime à partir du nom de fichier. par exemple:
string mimeType = MimeMapping.GetMimeMapping(filename);

si vous ne voulez pas ajouter de dépendances supplémentaires et que vous voulez toujours des requêtes indépendantes de la version, vous pouvez mélanger cette réponse sur la façon d'obtenir le type MIME dans différentes versions .NET avec cette réponse sur les constructions conditionnelles pour les versions cadres multiples .NET .
la première chose que j'ai faite a été d'éditer mon dossier de projet. Après la dernière définition de construction, j'ai ajouté le groupe de propriété comme indiqué dans la deuxième réponse:
<PropertyGroup>
<DefineConstants Condition=" !$(DefineConstants.Contains(';NET')) ">$(DefineConstants);$(TargetFrameworkVersion.Replace("v", "NET").Replace(".", ""))</DefineConstants>
<DefineConstants Condition=" $(DefineConstants.Contains(';NET')) ">$(DefineConstants.Remove($(DefineConstants.LastIndexOf(";NET"))));$(TargetFrameworkVersion.Replace("v", "NET").Replace(".", ""))</DefineConstants>
</PropertyGroup>
maintenant j'ai fourni une implémentation différente pour le MimeExtensionHelper de la première réponse, avec une autre pour tous les clients de .NET 4.5 ou plus tard appelant simplement System.Web.MimeMapping.GetMimeMapping :
#if (NET10 || NET11 || NET20 || NET30 || NET35)
public static class MimeExtensionHelper
{
static object locker = new object();
static MethodInfo getMimeMappingMethodInfo;
static MimeExtensionHelper()
{
Type mimeMappingType = Assembly.GetAssembly(typeof(HttpRuntime)).GetType("System.Web.MimeMapping");
if (mimeMappingType == null)
throw new SystemException("Couldnt find MimeMapping type");
ConstructorInfo constructorInfo = mimeMappingType.GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, null, Type.EmptyTypes, null);
if (constructorInfo == null)
throw new SystemException("Couldnt find default constructor for MimeMapping");
mimeMapping = constructorInfo.Invoke(null);
if (mimeMapping == null)
throw new SystemException("Couldnt find MimeMapping");
getMimeMappingMethodInfo = mimeMappingType.GetMethod("GetMimeMapping", BindingFlags.Static | BindingFlags.NonPublic);
if (getMimeMappingMethodInfo == null)
throw new SystemException("Couldnt find GetMimeMapping method");
if (getMimeMappingMethodInfo.ReturnType != typeof(string))
throw new SystemException("GetMimeMapping method has invalid return type");
if (getMimeMappingMethodInfo.GetParameters().Length != 1 && getMimeMappingMethodInfo.GetParameters()[0].ParameterType != typeof(string))
throw new SystemException("GetMimeMapping method has invalid parameters");
}
public static string GetMimeType(string fileName)
{
lock (locker)
{
return (string)getMimeMappingMethodInfo.Invoke(null, new object[] { fileName });
}
}
}
#elif NET40
public static class MimeExtensionHelper
{
static object locker = new object();
static MethodInfo getMimeMappingMethodInfo;
static MimeExtensionHelper()
{
Type mimeMappingType = Assembly.GetAssembly(typeof(HttpRuntime)).GetType("System.Web.MimeMapping");
if (mimeMappingType == null)
throw new SystemException("Couldnt find MimeMapping type");
getMimeMappingMethodInfo = mimeMappingType.GetMethod("GetMimeMapping", BindingFlags.Static | BindingFlags.NonPublic | BindingFlags.Public);
if (getMimeMappingMethodInfo == null)
throw new SystemException("Couldnt find GetMimeMapping method");
if (getMimeMappingMethodInfo.ReturnType != typeof(string))
throw new SystemException("GetMimeMapping method has invalid return type");
if (getMimeMappingMethodInfo.GetParameters().Length != 1 && getMimeMappingMethodInfo.GetParameters()[0].ParameterType != typeof(string))
throw new SystemException("GetMimeMapping method has invalid parameters");
}
public static string GetMimeType(string fileName)
{
lock (locker)
{
return (string)getMimeMappingMethodInfo.Invoke(null, new object[] { fileName });
}
}
}
#else // .NET 4.5 or later
public static class MimeExtensionHelper
{
public static string GetMimeType(string fileName)
{
return MimeMapping.GetMimeMapping(fileName);
}
}
#endif
également dans les versions antérieures à .NET 4.5, la classe statique MimeMapping héberge une instance statique appelée _mappingDictionary (de type MimeMapping.MimeMappingDictionaryBase ) que vous pouvez demander par réflexion afin d'ajouter de nouveaux MIME-Types qui peuvent ne pas encore être pris en charge.

il n'est toujours pas nécessaire que le type mime calculé par l'extension du fichier soit toujours correct.
disons que je peux enregistrer un fichier avec .png extention mais le fileformat que je peux définir comme "ImageFormat.jpeg".
donc dans ce cas le fichier que vous allez calculer, donnera un résultat différent... il peut en résulter un fichier de grande taille que l'original.
Si vous travaillez avec des images vous pouvez utiliser la imagecodecInfo et ImageFormat.

le message de Bryan Denny ci-dessus ne fonctionne pas pour moi car toutes les extensions n'ont pas une sous-clé" Content Type " dans le registre. J'ai dû modifier le code comme suit:
private string GetMimeType(string sFileName)
{
// Get file extension and if it is empty, return unknown
string sExt = Path.GetExtension(sFileName);
if (string.IsNullOrEmpty(sExt)) return "Unknown file type";
// Default type is "EXT File"
string mimeType = string.Format("{0} File", sExt.ToUpper().Replace(".", ""));
// Open the registry key for the extension under HKEY_CLASSES_ROOT and return default if it doesn't exist
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(sExt);
if (regKey == null) return mimeType;
// Get the "(Default)" value and re-open the key for that value
string sSubType = regKey.GetValue("").ToString();
regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(sSubType);
// If it exists, get the "(Default)" value of the new key
if (regKey?.GetValue("") != null) mimeType = regKey.GetValue("").ToString();
// Return the value
return mimeType;
}
maintenant, il fonctionne très bien pour moi pour tous les types de fichiers enregistrés et non enregistrés ou génériques (comme JPG, etc).

j'ai compilé une liste de sources fiables pour les valeurs de type mime et de type de contenu qui sont saisies uniquement sur l'extension du fichier (actuellement).
le paquet nuget est ici https://www.nuget.org/packages/FTTLib.dll /
et la source est ici https://github.com/brondavies/filetypetranslator /
cette bibliothèque est conçue pour avoir:
- Pas de dépendances externes
- pas d'accès au système de fichiers
- petite empreinte mémoire
- de Simples méthodes statiques (pas de méthodes d'extension et pas de instantiatable classes)
- insensible à la casse
- Portable - fonctionne dans les applications ciblant une CLR (.NET 2.0+)

FileExtension gérer l'extension du fichier et non le Mime. L'utilisateur peut modifier l'extension du fichier, alors vérifiez le Mime. Les exemples de codes associent Mime par extension de fichier, ceci est erroné et ne fonctionne pas.
besoin de récupérer le fichier contenttype et de vérifier si la table Mime contetType ce fichier selon l'extension de fichier. Maintenant, comment obtenir le ContentType du fichier?
utilisant FileUpload est ainsi: FileUpload.PostedFile.ContentType;
Maintenant, si je l'ai déjà le fichier, comme attiré votre ContentType?
