C# noobery

How do I execute console commands from C#?

I'm starting out with C#, moving over from C++. I'm only writing console apps for the moment.

In C++ I can write

system("pause");
system("cls");
system("color 0a");

And so on to execute things in a console. How do I do the same in C#? My googling has returned stuff that's above this level I think.

I thought the whole point of all this .NET faggotry was that you could call code in one language from another without any problems.
