7. Examples to understand Generic Delegates in C#.
What are Generic Delegates in C#?
The Generic Delegates in C# were introduced as part of .NET Framework 3.5 which does not require defining the delegate instance in order to invoke the methods. To understand the Generic Delegates in C# you should have the basic knowledge of Delegates.
Types of Generic Delegates in C#
C# provides three built-in generic delegates; they are as follows:
1. Func
2. Action
3. Predicate
What is Func Generic Delegate in C#?
The Func Generic Delegate in C# is present in the System namespace. This delegate takes one or more input parameters and returns one out parameter. The last parameter is considered as the return value. The Func Generic Delegate in C# can take up to 16 input parameters of different or the same data types. It must have one return type. The return type is mandatory but the input parameter is not mandatory.
Note: Whenever your delegate returns some value, whether by taking any input parameter or not, you need to use the Func Generic delegate in C#.
What is Action Generic Delegate in C#?
The Action Generic Delegate in C# is also present in the System namespace. It takes one or more input parameters and returns nothing. This delegate can take a maximum of 16 input parameters of the different or same data types.
Note: Whenever your delegate does not return any value, whether by taking any input parameter or not, then you need to use the Action Generic delegate in C#.
What is Predicate Generic Delegate in C#?
The Predicate Generic Delegate in C# is also present in the System namespace. This delegate is used to verify certain criteria of the method and returns the output as Boolean, either True or False. It takes one input parameter and always returns a Boolean value which is mandatory. This delegate can take a maximum of 1 input parameter and always return the value of the Boolean type.
Note: Whenever your delegate returns a Boolean value, by taking only one input parameter, then you need to use the Predicate Generic delegate in C#.
