Remarks

The TryGetValue method lets developers safely retrieve a value from a EntityConnectionStringBuilder without having to verify that the supplied key name is a valid key name. TryGetValue does not raise an exception when it is passed a nonexistent key. Calling TryGetValue with a nonexistent key puts the value null (Nothing in Visual Basic) in the value parameter.
