How can I have multiple extension methods on my own class, like this?

Question

string "hello world".toLower().toUpper().replace("o", "x");

How do I make my own class be able to have extension methods like string in the example above? Maybe not that usefull, but I just cant figure out how to do it

Those aren't actually extension methods - they're just methods that return a string, which enables you to chain them. — J. Steen, Nov 08 '12 at 21:30

These are called chained methods that can be used for fluent APIs.

One normally creates them by returning the same type from all method calls.

See Tips for writing fluent interfaces in C# 3.
