How to work with Action, Func, and Predicate delegates in C#

Jan 25, 2023

Learn how you can take advantage of delegates like Action, Func, and Predicate to facilitate callbacks and add flexibility to your code. sirtravelalot 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 . A delegate is a type-safe function pointer that can reference a method that has the same signature as that of the delegate. Delegates are used to define callback methods and implement event handling, and they are declared using the “delegate” keyword. You can declare a delegate that can appear on its own or even nested inside a class. What are Func and Action delegates? How can they be used? The basic difference between Func and Action delegates is that while the former is used for delegates that return value, the latter can be used for those delegates in which you don't have any return value. Func is a delegate that points to a method that accepts one or more arguments and returns a value. Action is a delegate that points to a method which in turn accepts one or more arguments but returns no value. In other words, you should use Action when your delegate points to a method that returns void. A Predicate is a delegate that accepts one or more generic parameters and returns a Boolean value — you can assume it is something like Func<T,bool>. Predicate delegates are typically used to perform search operations on some data based on a set of criteria. Programming Action delegates in C# You can take advantage of delegates in C# to implement events and call back methods. A delegate in C# is similar to function pointers of C++, but C# delegates are type safe. You can pass methods as parameters to a delegate to allow the delegate to point to the method. The following code snippet illustrates the syntax for using Action delegate. Action<TParameter> The following code listing shows how you can use Action delegate. This code snippet when executed would print the word “Hello!! !” in the console window. static void Main(string[] args)
