问题
I am trying to execute msbuild programically and cant execute the following command:
string command = string.Format(@\"C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\msbuild.exe \"\"{0}\\{1}.csproj\"\"\", _args.ProjectPath, _args.ProjectName);
the string gets rendered as:
C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\msbuild.exe \"C:\\...\\TestResults\\Foo 2011-08-31 16_29_40\\Out\\Foo\\solutionName\\projectName\\projectName.csproj\"
I then use new ProcessStartInfo(command). The problem seems to be the space between Foo and 2011. I get the following output:
MSBUILD : error MSB1008: Only one project can be specified.
Switch: 16_29_40\\Out\\Foo\\solutionName\\projectName\\projectName.csproj
How do I pass in the project file to msbuild?
回答1:
I would recommend stronlgy to go the official route via classes/interfaces in Microsoft.Build namespace. Microsoft uses this all over the place, so this should count for something...
Esp. the class Microsoft.Build.Execution.BuildManager and the Singleton Microsoft.Build.Execution.BuildManager.DefaultBuildManager is what you are after to run a build task... source code examples:

You need to use the Arguments property of the ProcessStartInfo to pass parameters.
e.g.
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();
However, for MSBuild specifically you should use the official method as Yahia mentions.

Here a full working example with a simple logger.
To build a 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 ..
and the logger class ( strongly derived of this 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 ArgumentException
|| ex is SecurityException
|| ex is IOException
)
{
throw new LoggerException("Failed to create log file: " + ex.Message);
}
else
{
// Unexpected failure
throw;
}
}
// For brevity, we'll only register for certain event types. Loggers can also
// register to handle TargetStarted/Finished and other events.
eventSource.ProjectStarted += new ProjectStartedEventHandler(eventSource_ProjectStarted);
eventSource.TaskStarted += new TaskStartedEventHandler(eventSource_TaskStarted);
eventSource.MessageRaised += new BuildMessageEventHandler(eventSource_MessageRaised);
eventSource.WarningRaised += new BuildWarningEventHandler(eventSource_WarningRaised);
eventSource.ErrorRaised += new BuildErrorEventHandler(eventSource_ErrorRaised);

}
void eventSource_ErrorRaised(object sender, BuildErrorEventArgs e)
{
// BuildErrorEventArgs adds LineNumber, ColumnNumber, File, amongst other parameters
string line = String.Format(": ERROR {0}({1},{2}): ", e.File, e.LineNumber, e.ColumnNumber);
WriteLineWithSenderAndMessage(line, e);
}

|| (e.Importance == MessageImportance.Normal && IsVerbosityAtLeast(LoggerVerbosity.Normal))
|| (e.Importance == MessageImportance.Low && IsVerbosityAtLeast(LoggerVerbosity.Detailed))
)
{
WriteLineWithSenderAndMessage(String.Empty, e);
}
}
void eventSource_TaskStarted(object sender, TaskStartedEventArgs e)
{

// To keep this log clean, this logger will ignore these events.
}

// Just the regular message string is good enough here, so just display that.
WriteLine(String.Empty, e);
indent++;
}

{
// The regular message string is good enough here too.

}

}
}

/// </summary>
private void WriteLine(string line, BuildEventArgs e)
{
for (int i = indent; i > 0; i--)
{

}
streamWriter.WriteLine(line + e.Message);
}
public string GetLogString()
{
var sr = new StreamReader(streamMem);
var myStr = sr.ReadToEnd();
return myStr;
}

Also be sure to use the correct MSBuild Framework Assemblies (i.e not the "4.0" version) ( see here )
