That's because you are passing an uninitialized value to a var- 
parameter. That only generates a hint, because a lot of code uses var- 
parameters also for parameters that do not yet have to be initialized  
(because the code predates the existence of the "out" keyword, or  
simply out of habit).

This is unrelated to string results specifically.
