Invoke run-time compiled object method (C#) [duplicate]

This question already has an answer here:

• Reflection: How to Invoke Method with parameters 5 answers

I'm trying to compiling code at runtime, and invoke a non-static method.

The main idea is taken from here: Compiling C# Code at Runtime

But in this example they are using a static method.

Is it possible to create an instance of some object and then invoke some methods with it ?

For example - lets say myClass has void RunMe() method:

Assembly assembly = results.CompiledAssembly;
var type = assembly.GetType("ns.myClass");
var obj = Activator.CreateInstance(type);  // New instance of myClass

How can I run the equivalent line to obj.RunMe() ?
