诊断第三方程序集中的问题，C＃.NET

Question

I want to find out how to diagnose issues in a third party assembly. I don't have source code of it. Are there tools or methodologies?

Thanks

Answer 1

我通常会使用Reflector来反汇编代码并查看它可能正在做什么。

Answer 2

You can go really oldschool and just decompile it with ILDasm.exe Of course that requires quite a bit of effort, and you have to be able to read IL.

And of course .NET Reflector is the standard goto, although you have to pay for it now, because RegGate broke their promise to keep it free.

Speaking of free, and just as good as Reflector ILSpy is an option too.

Answer 3

The Reflector in it's pro version provides debugging into third party assemblies: http://www.reflector.net/vspro/

(Though I've never tested it)

Answer 4

You can use JetBrian's dotPeek. It free and supports .NET 1.0-4.0 assemblies. Look here
