我正在调试托管代码的崩溃转储，当使用 !threads 在这里显示所有线程时，几个线程具有 Exception 字段值和各种异常。

我的问题是如何快速识别哪个异常是导致进程崩溃的根异常？为什么这么多线程与异常值相关联的任何想法 - 我认为应该只有一个线程（具有未处理的异常）导致进程崩溃，为什么这么多线程显示异常？:-)

提前谢谢，乔治

这是！threads 的一部分的输出示例，FooException 和 GooException 是我的应用程序定义的异常类型。

在调试转储时，可以使用“~”命令找到故障线程，然后查找“.”。旁边的线程之一。然后你切换到那个线程并运行kb。您应该在本机调用堆栈中看到对RaiseException()的调用。

一旦您知道感兴趣的线程， 您也可以运行!clstack来获取托管调用堆栈。

您还可以在线程上运行!pe以转储 (!PrintException) 输出。

这应该让你大部分时间..根据我概述的步骤随意评论和分享更多数据，我们应该能够快速解决这个问题

要回答您的问题，在线程上出现异常的一段时间内，!threads 输出将表明这一点。所以看起来你有很多异常需要追踪。

另一种技术（值得另一个标签:-)

要跟踪其他异常，您可以使用 Visual Studion 并在 UI 中启用对抛出异常的中断。如果你胆子大，可以运行 Mdbg 并运行以下命令来捕捉被抛出的异常

Open a VS.NET 2005/2008 Command Prompt
mdbg
>pro //Lists the processes
>a <PID> //attach to the processes
>ca ex //catches all exceptions
>g //go until break
//When it breaks on an exception
>where -v -c 200 // dumps the managed call stack (verbose) with a count of 200 frames
>print //prints out locals on the stack
>g //go to next exception
>de //Detach when done.. process stays running
>q //Quit the debugger

MDbg 的好处是您可以进行源代码级调试。（也许我会为这些创建一个MDbg标签）

谢谢，亚伦

George2，您是否尝试过命令“！analyze -v”？你加载了 sos dot net 调试器扩展吗？（尝试 .chain 命令查看它是否在其中）。分析 -v 很有帮助。. .
