Today I’m going to focus a bit on the System.DateTime. This nice little value type (struct) has been in the BCL since the beginning, and while being broadly used to represent an instance of a date and time, there are many great properties, methods, and operators in this class that perhaps folks are less ......

I will discuss several different methods for returning collections in a read-only fashion with their pros and cons, including performance implications. The Problem Many times you will create a type ......
