What is method overloading in C#?

Two or more than two methods having the same name but different parameters is what we call method overloading in C#.

Method overloading in C# can be performed by changing the number of arguments and the data type of the arguments.

Let’s say you have a function that prints multiplication of numbers, then our overloaded methods will have the same name but different number of arguments −

public static int mulDisplay(int one, int two) { }
public static int mulDisplay(int one, int two, int three) { }
public static int mulDisplay(int one, int two, int three, int four) { }

The following is an example showing how to implement method overloading −

Example

using System;
public class Demo {
   public static int mulDisplay(int one, int two) {
      return one * two;
   }

   public static int mulDisplay(int one, int two, int three) {
      return one * two * three;
   }

   public static int mulDisplay(int one, int two, int three, int four) {
      return one * two * three * four;
   }
}

public class Program {
   public static void Main() {
      Console.WriteLine("Multiplication of two numbers: "+Demo.mulDisplay(10, 15));
      Console.WriteLine("Multiplication of three numbers: "+Demo.mulDisplay(8, 13, 20));
      Console.WriteLine("Multiplication of four numbers: "+Demo.mulDisplay(3, 7, 10, 7));
   }
}

Output

Multiplication of two numbers: 150
Multiplication of three numbers: 2080
Multiplication of four numbers: 1470
