While passing objects as arguments is a standard and familiar way to invoke methods, providing methods as arguments to other methods is less so. Nonetheless, we often must pass a method as a parameter to another method when working with event handling in C#. We do this using delegates.
I provided an overview of delegates in an earlier article here. In this article, we’ll examine how we can work with Action, Func, and Predicate delegates in C#. To work with the code examples provided in this article, you should have Visual Studio 2022 installed in your system. If you don’t already have a copy, you can download Visual Studio 2022 here.
