Calling a method on a static class given its type name and method names as strings

Question

How could I go about calling a method on a static class given the class name and the method name, please?

For example:

Given System.Environment

Answer 1

Just

Type.GetType(typeName).GetMethod(methodName).Invoke(null, arguments);

where typeName is the name of the type as a string, methodName is the name of the method as a string, and arguments is an array of objects containing the arguments to call the method with.
