How to sort member functions with a class

I like to see member functions within a class alphabetically sorted. For example:

pubic class MyClass{
    public void MethodB(){
    }

    public void MethodA(){
    }
}

should get converted to 

pubic class MyClass{

    public void MethodA(){

    }

    public void MethodB(){

    }

}

I'd like this to happen when I run "Cleanup Code". How can I do this?
