The TryGetValue method lets developers safely retrieve a value from a ULConnectionStringBuilder without needing to first call
the ContainsKey method. Because TryGetValue does not raise an exception when you call it, passing in a nonexistent key, you
do not have to look for a key before retrieving its value. Calling TryGetValue with a nonexistent key places the null value
(Nothing in Visual Basic) in the value parameter.
