The output will be : theLocation is null theTime is null It will be like this because you did not initialize them and C# use null as default value for classes instance.

theTime is a value type. As such, an uninitialized DateTime. variable is set to the default value of midnight on 1/1/1. the year 1 A.D

Yeah, I know that value type have default values other than null. But if you know the answer, then why did you ask the question in the first time ? ^^
