Getting ready

Remember when we used Tuples at the beginning of this chapter? Well we were using code similar to the following to get the values returned by the Tuple literal.

var (average, studentCount) = ch1.GetAverageAndCount(scores);

This was deconstructing the parts of the Tuple into the new variables average and studentCount. I do not, however, want to take a look at Tuples again. What I want to do is show how you can implement a deconstruction declaration on any type. To do this, all that we need to do is ensure that  the type has a deconstructor method. We will modify our existing Student class to add a deconstructor.
