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
sxe clr
!name2ee Beyondbit_PDHB_SynAdmin!Beyondbit.SynAdmin.SynAdminProject.OutNewProjectBook.btnManage_Click
!bpmd -md 00000642803d2ae8

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：
