Thanks was having problems with .net resolver.
This is a short tutorial on how to use MSIL Decompiler.
You need .NET Framework 4.5 I think and a copy of Visual Studio
Go into your windows start menu (button in the lower left of your screen (THE WINDOWS LOGO))
Type in the search bar "Visual Studio"
You should see visual studio command prompt.
Open it and type in "ildasm"
^ that window should pop up
Select file -> open
Then open your Assembly-CSharp.dll file in it.
The code is in PE32 executable (DLL) (console) Intel 80386 Mono/.Net assembly type ASM bytecode
