The TryGetValue method lets developers safely retrieve a value from a OdbcConnectionStringBuilder without needing to verify that the supplied key name is a valid key name. Because TryGetValue does not raise an exception when you pass 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 value null (Nothing in Visual Basic) in the value parameter.
