How to walk a native object in WinDbg?

Question

I am investigating what is taking up lots of memory in my app. Using the !DumpObj command, I can get around the managed objects. But how do I do the equivalent for native objects? For example, this .NET object has a pointer to native code. I am stuck here... how do I do the equivalent of !DumpObj from here? I have all the source and symbols.

Answer 1

The d* command should give you contents of the memory d

Answer 2

dt module!typedef addr

e.g., dt MyModule!MyClass 0x12345678

Answer 3

You can dump the object by running the following command:

!object address.

In addition also the object header can be dumped. The object header is always located at 18h bytes prior to the object in memory. It can be dumped with the following command

!dt nt!_object_header address-18h

To figure out the the type you might want in addition to also dump the object type. This can be achieved with the following command.

!dt nt!_object_type address-of-type

The address of the type is printed as part of the dump of the object header. The corresponding field name is Type.
