String.Format against string.Format. Any issues?

Question

Is there any performance differences between string.Format and String.Format ? As far as i understand string is a shortcut for System.String and there's no difference between them. Am i right?

Thanks!

Answer 1

Those are exactly the same. "string" is just an alias for "System.String" in C#

Answer 2

string and String both resolve to System.String. So no there is no difference at all.
