Set german lamguage

Hi everyone,

I have a program, written in C# using GTK#, that is localized for english. I want to translate it to german and changed all texts inside the sourcecode. But I have a problem: All dialogs (Color-Dialog, Yes/Now-Dialogs) use english words and I don't know, how to translate them. I'm pretty sure, that I can switch the language of the gtk-part to german, but I have no Idea, how to do that.

I should add, that I'm not that familiar with Mono and GTK. Can anybody help me?

Thanks for your help!
