You can use the Profiling API to add behavior, like this: http://www.codeproject.com/KB/cs/IL_Rewriting.aspx

Modifying the assembly directly is not something you should be pursue if you want to get this done before you graduate.  Leverage existing .NET tools.  Disassemble the assembly first with ildasm.exe, now it becomes a text parsing effort.  Put humpty-dumpty back together with ilasm.exe.  An open source project that injects code is Spring.NET.
