Can elaborate difference between Func vs. Action vs. Predicate?

Question

Aryan Kumar · Answer

Sure. Func, Action, and Predicate are all delegates in C#. A delegate is a reference to a method. Func, Action, and Predicate differ in the type of method they refer to.

Func refers to a method that takes zero or more parameters and returns a value.
Action refers to a method that takes zero or more parameters and does not return a value.
Predicate refers to a method that takes one parameter and returns a boolean value.

Here are some examples of how Func, Action, and Predicate can be used:

Func can be used to create a function that takes two numbers as input and returns their sum.
Action can be used to create a function that prints the current date and time.
Predicate can be used to create a function that checks if a number is even.

Here is a table that summarizes the differences between Func, Action, and Predicate:

Delegate	Parameters	Return type
Func	Zero or more	Value
Action	Zero or more	Void
Predicate	One	Boolean
