Declare and Instantiate Delegate in C#
Here, we will create a method and create the delegate to point the method, delegates are just like a function pointer in C. we can invoke method using delegates.
C# code to declare and instantiate delegate
The source code to declare and instantiate delegate is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.
//C# program to declare and instantiate delegate.
using System;
delegate void MyDel();
class Sample
{
void Method1()
{
Console.WriteLine("Method1() called");
}
static void Main()
{
Sample S = new Sample();
MyDel del = new MyDel(S.Method1);
del();
}
}
Output
Method1() called
Press any key to continue . . .
Explanation
In the above program, we created a Sample class that contains a method instance Method1() and static method Main().
Method1() is used to print a message on the console screen.
delegate void MyDel();
Here we created a delegate according to the method declaration.
MyDel del = new MyDel(S.Method1);
del();
In the above code we bind the Method1() to the delegate del and called the method Method1() using delegate del that will print "Method1() called" on the console screen.
