Question

环境：

C＃项目，Visual Studio 2008，C＃，。Net 3.5，MSBuild

目的：

为我的C＃项目运行我自己的自定义构建任务，并且基于平台（Soln配置平台），我在构建之前对Project对象本身进行了一些操作。就像将BuildAction设置为EmbeddedResource等。

完成后，我致电Project.Build()。我不想在GlobalEngine上使用Project对象，因为一旦你修改了Project对象，它就会将文件标记为脏（并从TFS结账）。

问题：

因为我正在使用我自己的Engine实例和Project，所以我无法将构建输出，错误指向VS.我只从Project.Build()中得到一个bool。我没有发现任何我可以联系的事件，可以允许访问BuildErrorEventArgs等类似事件。我知道我可以使用Log.LogErrorEvent()将消息记录到VS错误列表中。但我需要首先获得构建输出本身。

代码：

// Execute method in my custom build task class, derives from a BaseTask class
public override bool Execute()
{
Engine engine = new Engine();
Project project = new Project(engine);
project.Load(ProjectName);
Log.LogMessage(Microsoft.Build.Framework.MessageImportance.High, "Got the Project");
// Set the project's DefaultTargets to "Build" to be able to build with CSharp targets
project.DefaultTargets = "Build";
IsBuilt = project.Build(); // Isbuilt bool is a property in my BaseTask class
// Here's where I want to get Build output and direct it to VS output window and errorlist window

engine.Shutdown();
return base.Execute();
}

我想通了，只需实现自定义记录器并在事件处理程序中使用Log.LogMessage或LogError

public class MyCustomBuildLogger : ILogger
{
    private IEventSource source;

 public void Initialize(IEventSource eventSource)
        {
            this.source = eventSource;
            //Events.ProjectStarted += new ProjectStartedEventHandler(Events_ProjectStarted);
            //Events.ProjectFinished += new ProjectFinishedEventHandler(Events_ProjectFinished);
            Events.WarningRaised += new BuildWarningEventHandler(Events_WarningRaised);
            Events.ErrorRaised += new BuildErrorEventHandler(Events_ErrorRaised);
            Events.BuildFinished += new BuildFinishedEventHandler(Events_BuildFinished);
            //Events.BuildStarted += new BuildStartedEventHandler(Events_BuildStarted);
            Events.MessageRaised += new BuildMessageEventHandler(Events_MessageRaised);
            //Events.CustomEventRaised += new CustomBuildEventHandler(Events_CustomEventRaised);

            Events.MessageRaised += new BuildMessageEventHandler(Events_MessageRaised);
        }

 void Events_ErrorRaised(object sender, BuildErrorEventArgs e)
        {
            // This logs the error to VS Error List tool window
            Log.LogError(String.Empty, 


             String.Empty,
                    String.Empty, 
                    e.File, 
                    e.LineNumber, 
                    e.ColumnNumber,
                    e.LineNumber, 
                    e.ColumnNumber, 
                    e.Message);
           }
}

并在MyCustomBuildTask类中设置并加载引擎和项目，

_logger = new MyCustomBuildLogger();
_logger.Log = Log;
_engine.RegisterLogger(_logger);

如何在自定义构建任务中运行Project.Build（）时获取构建输出，错误列表？
