Apparently I couldn't explain my point. Saying ExampleVoid I meant private void Example() { }

Here ExampleString() and ExampleVoid() seems as a method and you can use this if have returned something from here . such like Public string ExampleVoid(){ string yourvalue=; //your code here return yourvalue; }
