Documentation for this section has not yet been entered.
You can dynamically determine the type of the Tuple`3.Item2 component in one of two ways:
By calling the GetType method on the value that is returned by the Tuple`3.Item2 property.
By retrieving the Type object that represents the Tuple`3 object, and retrieving the second element from the array that is returned by its Type.GetGenericArguments method.
