本文介绍如何利用Windbg中的!mdt命令来检查指定类型的字段或对象实例的字段，甚至可以递归查看整个对象图。通过几个具体的例子演示了如何对不同类型如System.DateTime、System.Guid等进行分析。

!mdt allows you to dump the fields of a given type by type name or to examine the fields of an object or value type instance. Not only can you examine the fields of an object or value type instance, but you can also examine an entire object graph by specifying the “-r” (recursive) switch. Want to examine a local variable or argument? No problem. Just enter “!mdt <Var Name>”, and voila! The best way to demonstrate the power of this command is with a few examples.

0:000> !mdt System.DateTime 003bef0c
003bef0c (System.DateTime) 2008/01/02 03:04:05.678 VALTYPE (MT=65cd9e98, ADDR=003bef0c)

0:000> !mdt theGuid
003bef1c (System.Guid) {29b9c9c8-3751-42be-8c7a-8b92ff499588} VALTYPE (MT=65cd6c60, ADDR=003bef1c)

0:000> !mdt ConsoleTestApp.TestStruct
TestStruct

Member2: uint

0:000> !mdt ConsoleTestApp.TestStruct 003bef04
