问题
VB.NET and C# (and other language) compilers generate MSIL code. How can I see that code?
What is there in that file? Where does that file reside and how can I access that?
Second question:
How do I compile a C# program from the cmd prompt and how do I check each and every file created using that compiler?
回答1:
Managed DLLs and EXEs are in MSIL.
You can see the MSIL using ildasm.exe.
回答2:
You'll need a decompiler, such as Telerik's JustDecompile (free). With it you can open any .NET executable or DLL and examine the generated MSIL (in the language of your choice).

The Ildasm.exe tool is installed with the framework along with VS. You can find it in the <Program Files>\Microsoft SDKs folder.
It opens .EXE and .DLL files.
