Linq OfType<T> expression
I just discovered a function in Linq that will save me a bit of typing and allow me to better express myself.
For a long while, I've written this:
ColorWrapper x = combo.Items.Where( obj => obj is ColorWrapper ).Cast< ColorWrapper >().FirstOrDefault(cw => cw.Color == value);
Today, I realized that the framework designers were ahead of me, and provided OfType<T>, which does the same thing as follows;
ColorWrapper y = combo.Items.OfType<ColorWrapper>().FirstOrDefault(cw => cw.Color == value);
Lesson Learned: Pay more attention to ALL of the aspects offered by a new technology, they all have their appropriate uses.
