c# - 如何获取有关异常的更多信息

Question

我在 64 位 Windows 7 上的 Visual Studio 2008 中创建了一个解决方案。

有效。

当我将它移到另一台机器上时，同样是 win 7、64 位，它崩溃了，几乎没有任何信息。

原来的问题是这样的:

call was rejected by callee

然后我实现了这个解决方案:

how to properly GetTypeFromProgID for visual studio 2008

但是，现在我的问题是，当我在另一台机器上运行可执行文件时，程序立即崩溃并显示以下信息:

我将代码包装在 try/catch 中，但仍然没有收到正确的错误消息:

static void Main()
{
    try
    {
        EnvDTE80.DTE2 dte;
        object obj = null;
        System.Type t = null;

        // Get the ProgID for DTE 8.0.
        t = System.Type.GetTypeFromProgID("VisualStudio.DTE.9.0",
          true);
        // Create a new instance of the IDE.
        obj = System.Activator.CreateInstance(t, true);
        // Cast the instance to DTE2 and assign to variable dte.
        dte = (EnvDTE80.DTE2)obj;

        // Register the IOleMessageFilter to handle any threading
        // errors.
        MessageFilter.Register();
        // Display the Visual Studio IDE.
        dte.MainWindow.Activate();


        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new Form1());

        // For example, get a reference to the solution2 object
        // and do what you like with it.

        // All done, so shut down the IDE...
        dte.Quit();
        // and turn off the IOleMessageFilter.
        MessageFilter.Revoke();

    }
    catch (Exception e)
    {
        MessageBox.Show(e.ToString());
    }
}

我如何确定异常发生的确切位置以及异常是什么？

我确实有一些非托管代码:

using System;
using System.Collections.Generic;
using System.Text;
using EnvDTE;
using EnvDTE80;
using EnvDTE90;
using System.Runtime.InteropServices;

    public class MessageFilter : IOleMessageFilter
    {
        //
        // Class containing the IOleMessageFilter
        // thread error-handling functions.

        // Start the filter.
        public static void Register()
        {
            IOleMessageFilter newFilter = new MessageFilter();
            IOleMessageFilter oldFilter = null;
            CoRegisterMessageFilter(newFilter, out oldFilter);
        }

        // Done with the filter, close it.
        public static void Revoke()
        {
            IOleMessageFilter oldFilter = null;
            CoRegisterMessageFilter(null, out oldFilter);
        }

        }

        // Thread call was rejected, so try again.
        int IOleMessageFilter.RetryRejectedCall(System.IntPtr
          hTaskCallee, int dwTickCount, int dwRejectType)
        {

            // flag = SERVERCALL_RETRYLATER.

                return 99;
            }
            // Too busy; cancel call.
            return -1;
        }

        int IOleMessageFilter.MessagePending(System.IntPtr hTaskCallee,
          int dwTickCount, int dwPendingType)
        {
            //Return the flag PENDINGMSG_WAITDEFPROCESS.
            return 2;
        }

        // Implement the IOleMessageFilter interface.
        [DllImport("Ole32.dll")]
        private static extern int
          CoRegisterMessageFilter(IOleMessageFilter newFilter, out 
          IOleMessageFilter oldFilter);
    }
    [ComImport(), Guid("00000016-0000-0000-C000-000000000046"),
    InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
    interface IOleMessageFilter
    {
        [PreserveSig]
        int HandleInComingCall(
            int dwCallType,
            IntPtr hTaskCaller,
            int dwTickCount,
            IntPtr lpInterfaceInfo);

        [PreserveSig]
        int RetryRejectedCall(

    }
}

在给我带来麻烦的机器上安装 VS 2008 Express 后，我现在得到这个:

您也可以尝试订阅 AppDomain.CurrentDomain.UnhandledException 事件:

AppDomain.CurrentDomain.UnhandledException += 
      (sender, e) => MessageBox.Show(e.ExceptionObject.ToString());

在 Main 方法的顶部执行此操作。
