Is there a difference in use or not the "this" keyword to reference a method inside the same class?

Answer 2

In that specific example there is no difference - it will compile to identical bytecode.

It only makes a difference if there is a local variable or parameter with the same name as the method you want to call, in which case you need to write this to refer to the member and not the local variable.

Answer 3

There is no difference from an execution standpoint. As you imply, some people use this, some don't.

Use the standard you've decided is correct, unless you are overridden by company standards.

Answer 4

Not performance, they will compile to the same IL.

The thing with the this keyword is that it you don't have local variables with the same naming as the class members.

private void MyMethod2()
{
    Action MyMethod1 = MyMethod2;
    MyMethod1(); // recursive call to MyMethod2

    this.MyMethod1(); // call to real MyMethod1
}

Other than that some people like it, some does not. Follow the code standard in your team.
