Viewing the CLI of a portable executable

What is a good program to get a nice, human readable form of the CLI of a portable executable file? I don't want a full disassembler because I'd like to learn how they work (or, in my case, not work).

From stackoverflow

• You should be to use ILDASM to extract the IL

  ildasm.exe MyProgram.exe /out=MyProgram.il
  

• Hi.

  I recommend reflector.

  It can show you IL, C# and a lot more.

  Frank Meulenaar : Nice, I didn't know it could show the IL.
