The first thing is this code has at least 3 syntax errors and doesn't
compile. Please post compilable code as it makes it a lot easier for

No. It looks fine to me.

I would have done the following which works without a lock and then
used a simple critical section instead of a ReaderWriterLock
(a CS is a lot more efficient than a RWLock)
public static bool CanContinue(int usn , string sessionId )
{
string sess = _loggedUsers[usn];
return (sess != nil) && (sess==sessionId);
}
