将输出窗口重定向到日志文件

Question

当我的应用程序启动时,我看到以下行被写入输出窗口:

'MyApp.exe' (Managed (v2.0.50727)): Loaded 'C:\WINDOWS\assembly\GAC_MSIL\PresentationFramework.Luna\3.0.0.0__31bf3856ad364e35\PresentationFramework.Luna.dll', Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

我想将这些行添加到我的日志文件中(并为一些性能测量指定时间戳).我试着用我创建的以下类来做到这一点.

public static class ConsoleLogger
{
    public class LogWriter : TextWriter
    {
        public LogWriter()
        {
        }

        public override Encoding Encoding
        {
            get { return Encoding.UTF8; }
        }

        public override void Write(string value)
        {
            Logger.Info(value);                
        }
    }

    public static void RedirectConsoleLog()
    {
        Console.SetOut(new LogWriter());
    }
}

但这不起作用.永远不会调用Write()方法.有任何想法吗？

这些行是由调试器生成的。调试器可以生成的通知类型记录在本 SDK 文章中。DLL 加载通知与事件 6 LOAD_DLL_DEBUG_EVENT 对应。该列表与右键单击“输出”窗口时在上下文菜单中找到的内容几乎一致。您感兴趣的“模块加载消息”。

这有几个含义。首先，只有调试器才能收到这些通知，通常在部署程序后运行程序时不会收到这些通知。Windows 中的一个硬限制是调试器必须是一个单独的进程，程序无法调试自身。您计划中的最后一个问题是 IDE 不支持将现在发送到输出窗口的内容重定向到文件中。

除非您编写自己的调试器，否则您无法完成这项工作。技术上可行，请下载MDbg 示例。实际上不是。
