Quit the program when catching error in C#?

With Python, I normally check the return value. And, if there's an error, I use sys.exit() together with error message.

What's equivalent action in C#?

• Q1 : How to print out an error message to stderr stream?
• Q2 : How to call system.exit() function in C#?
• Q3 : Normally, how C# programmers process the errors? Raising and catching exceptions? Or, just get the return value and exit()?
