Your code is throwing an exception.

This is happening in this statement:

if(ConfigurationType.Add()) //Add t to value

because you are adding a String, which will be returned by the method Add(), and you are trying to implicitly convert Value, containing this string, to bool in the if() statement.
Such conversion is impossible. This is why you are getting an exception.
