windbg+psscor2调试.net程序

加载clr调试插件 

.load psscor2

设置调试符号文件地址，一般指向网站的bin目录下，里面每个Dll会有一个 PDB文件

.sympath D:\website\pdhbj\Pdhb.SynAdmin\bin 

或执行File>>Symbol File Path，填入： 

 srv* D:\website\pdhbj\Pdhb.SynAdmin\bin*http://msdl.microsoft.com/download/symbols

在CLR的Exception抛出来的时候，能断点停下来，方便调试

执行

!pe 得到如下结果：

Exception object: 00000001bf44b470

Exception type: System.NullReferenceException

Message: hello

InnerException: <none>

StackTrace (generated):

<none>

StackTraceString: <none>

HResult: 80004003 

这样我们就知道Exception的Message文本了

!dae

 出现以下文本：
