Windbg 调试.net程序
// 1 - 这命令是再加载了mscorwks后WinDBG会断下来，这样就有机会加载SOS。
sxe ld:mscorwks
// 2 - 看是否加载了mscorwks，如果没有加载就使用按照上面方式做
lmm mscorwks
// 3 - 使用这个命令自己指定和.NET匹配的SOS
.load C:\Windows\Microsoft.NET\Framework\v2.0.50727\sos.dll
// 4 - 使用这个命令根据已加载的mscorwks来确定并加载SOS
.loadby sos mscorwks
// 5 - 查看加载的SOS. lists all loaded debugger extensions in their default search order
.chain
// 6 - 如果sos加载成功, 那么!help可以查看sos扩展的命令
!help
// !Name2EE 显示指定模块中指定类型或方法的 MethodTable 结构和 EEClass 结构。
// 7 - 使用!Name2EE *!ModuleName.Type来查看已经Module Address
例如: !Name2EE *!CQ2BCFAPInterface.Program
Module: 002b2c5c (CQ2BCFAPInterface.exe) // Module Address得到
Token: 0x02000016
MethodTable: 002b30c8
EEClass: 002b1d44

// 8 - 使用!DumpModule
// 显示有关指定地址处的模块的信息。 -mt 选项显示模块中定义的类型和模块所引用的类型

/// 这个命令比较好用, 得到当前运行地址的method desc地址

然后, 可以用!dumpmd methoddesc_addr查看一些东西
要注意查看程序抛出的异常类型, 然后, 当异常发生时, 直接断下来, 命令
!soe -create system.Exception -1
表示当程序出现system.Exception后, 断下来, 此时用!dso查看对象, 然后用!do命令观察对象中的数据值
////////////////////////////////////////////////////
总的来说, 用Windbg来调试.net程序, 不怎么好用. 一点都不直观. 无法直观的观察到managed code的运行情况.
特别是变量的值. 异常等, 看得都不是很清楚. 可以这么说, 花费大力气, 却未必能得到讨好的结果;.
