Debugging in VS without the source code

.net, c#, debugging, visual-studio-2010

Solution

This is exactly why I paid for Reflector. Need to debug someone else's assembly? It works perfectly.

Problem

I need to debug some assemblies due to they throw exceptions. It's my assemblies but I don't have the source code of them. What I have is their pdb files. Is there any way to debug that assemblies by Visual Studio? --EDIT-- Of course, I also can disassembly them to get *.il files of them. Would it help me somehow?
