exécution programmatique de msbuild

vous devez utiliser la propriété Arguments du ProcessStartInfo pour passer les paramètres.

p.ex.

var p = new Process();
p.StartInfo = new ProcessStartInfo(@"C:\Windows\Microsoft.NET\Framework\v4.0.30319\msbuild.exe")      
p.StartInfo.Arguments = string.Format(@"{0}\{1}.csproj", _args.ProjectPath, _args.ProjectName)

p.Start();

Cependant, pour MSBuild spécifiquement, vous devez utiliser la méthode officielle comme Yahia mentionne .

voici un exemple complet de fonctionnement avec un simple logger.

pour construire une solution:

        using Microsoft.Build.Evaluation;
        using Microsoft.Build.Execution;

        string projectFileName = "C:\Users...\MySolution.sln";//<--- change here can be another VS type ex: .vcxproj
        BasicLogger Logger = new BasicLogger();
        var projectCollection = new ProjectCollection();
        var buildParamters = new BuildParameters(projectCollection);
        buildParamters.Loggers = new List<Microsoft.Build.Framework.ILogger>() { Logger };
        var globalProperty = new Dictionary<String, String>();
        globalProperty.Add("Configuration", "Debug"); //<--- change here 
        globalProperty.Add("Platform", "x64");//<--- change here 
        BuildManager.DefaultBuildManager.ResetCaches();
        var buildRequest = new BuildRequestData(projectFileName, globalProperty, null, new String[] {  "Build" }, null);
        var buildResult = BuildManager.DefaultBuildManager.Build(buildParamters, buildRequest);
        if (buildResult.OverallResult == BuildResultCode.Failure)
        {
            // catch result ..
        }          
        MessageBox.Show(Logger.GetLogString());    //display output ..

et la classe logger (fortement dérivée de ce msdn logger ):

 public class BasicLogger : Logger
    {
        MemoryStream streamMem = new MemoryStream();
        /// <summary>
        /// Initialize is guaranteed to be called by MSBuild at the start of the build
        /// before any events are raised.
        /// </summary>
        public override void Initialize(IEventSource eventSource)
        {

            try
            {
                // Open the file
                this.streamWriter = new StreamWriter(streamMem);
                //this.streamWriter = new StreamWriter(logFile);
            }
            catch (Exception ex)
            {
                if
                (
                    ex is UnauthorizedAccessException
                    || ex is ArgumentNullException
                    || ex is PathTooLongException
                    || ex is DirectoryNotFoundException
                    || ex is NotSupportedException

                    || ex is SecurityException
                    || ex is IOException
                )
                {
                    throw new LoggerException("Failed to create log file: " + ex.Message);

assurez-vous également d'utiliser les bons assemblages MSBuild Framework (I. e pas la version "4.0") (voir ici )
