Learn About Single Cast Delegates In C#

In this blog, you will learn about single cast delegates in c#.

Introduction

 

In this article, I will explain about single delegates in C#. Single cast delegates only hold the reference of a single method. A single cast delegate derives from the System. Delegate class. It’s used to invoke a single method at a time.

 

Syntax of delegates

 

[access_modifier] delegate [return type] [delegate name] ([parameters])

 

Declarations

 

public delegate TypeOfDelegate Delegate_Name();

 

Examples

 

public delegate string myDelegates(string FirstName, string LastName);

 

Single cast delegates have some of the features in C#  as below

• We can pass the method as a parameters
• It is type-safe and this is similar to C++ function pointers.
• It helps us to Invoke and define the callback methods

Sample Program

public delegate strin gmyDelegates(string FirstName, string LastName);
public class SubClass {
    public string UserName(string FirstName, string LastName) {
        return FirstName + "" + LastName + "";
    }
}
public class Personal {
    static void Main(string[] args) {
        SubClass subClass = newSubClass();
        myDelegates myDelegates = newmyDelegates(subClass.UserName);
        myDelegates("Manikandan", "M");
    }
}
//Output : Manikandan M
