04 Feb C# Method Overloading

In C#, we can easily create and call methods with similar names and different parameters. Two or more methods can have similar names in C#, for example:

int Example(int age)
int Example(int marks, int rank)
float Example(float points)

In the above example, note the Method name is the same, but the parameters are different. Therefore, the concept of overloading works by changing the,

• Number of Arguments
• Type of Arguments

Example 1 – Overloading Methods in C#

Let us see an example where we have methods with similar name and arguments with similar datatypes:

using System;

namespace Demo
{
   public class Studyopedia  
   {  
      public static int ProdMethod(int x,int y){  
          return x * y;  
      }  
      
      public static int ProdMethod(int w, int x, int y, int z)  
      {  
          return w * x * y * z;  
      } 

      static void Main()  
      {  
          int mul1 = ProdMethod(2, 3);
          int mul2 = ProdMethod(5, 6, 7, 8);

          Console.WriteLine("Product of two numbers = {0}",mul1);  
          Console.WriteLine("Product of four numbers = {0}",mul2);  
      } 
    }
}

Output

Product of two numbers = 6
Product of four numbers = 1680

Example 2 – Overloading Methods in C#

Let us see an example where we have methods with similar name but arguments with different datatypes:

using System;

namespace Demo
{
   public class Studyopedia  
   {  
      // Method 1
      public static int ProdMethod(int x,int y){  
          return x * y;  
      }  
      
      // Method 2 with similar name but arguments with different datatypes
      public static float ProdMethod(float x,float y){  
          return x * y;  
      }  
      
      // Method 3 with similar name but arguments with different datatypes
      public static double ProdMethod(double x,double y){  
          return x * y;  
      }  

      static void Main()  
      {  
          // Callthe three methods
          int mul1 = ProdMethod(2, 3);
          float mul2 = ProdMethod(5.7f, 7.8f);
          double mul3 = ProdMethod(8.25, 6.27);

          Console.WriteLine("Product of two int numbers = {0}",mul1);  
          Console.WriteLine("Product of two float numbers = {0}",mul2);  
          Console.WriteLine("Product of two double numbers = {0}",mul3);          
      } 
    }
}

Output

Product of two int numbers = 6
Product of two float numbers = 44.46
Product of two double numbers = 51.7275
