Re: is it possible to use out and ref keyword together???

In 99.9% of cases. There are (rare) occasions when you genuinely intend to
reassign a reference that was passed in, and you can't (for some reason)
return the new reference in the return value.

But yes; in many cases "ref" on a reference type parameter is due to
misconceptions. In contrast, "out" is IMO becoming more mainstream and more
useful that "ref", largely due to adopting the TryGetValue and TryParse
signatures from the 2.0 classes.
