Need some help getting information out of a c# client program

[lightofdarkness]

Hello!

I want to write a tool for a game client. It's not even a cheat or sth like that. Only a statistics/information tool. The Client is a c# program without any anti-cheat protection. I decompiled the source code (dotPeek) and also found the method which is called when my desired information comes from the server. Now my question is: How can i get that out of the program? Is there a way to change the source code and recompile it (very big programm - i'm not very good in c#). Or do you see any chance to get the data the server sends or do you think memory reading is the way to go?

The information i'm interested about is a array of int codes + an id from the server - and on the other side a selection from the user going to the server.

Thank you, Dominik
