Method Overloading

Method overloading is the type of static polymorphism, we can create multiple methods with the same name using method overloading.

Here, we will overload the Sum() method based on types of arguments.

C# program to implement method overloading based on types of arguments

The source code to demonstrate method overloading based on the type of arguments is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to demonstrate method overloading 
//based on types of arguments

using System;

class MethodOver
{
    static double Sum(int a, int b)
    {
        float r = 0;

        r = a + b;
        return r;
    }
    static double Sum(int a, float b)
    {
        float r = 0;

        r = a + b;
        return r;
    }

    static double Sum(int a, double b)
    {
        double r = 0;

        r = a + b;
        return r;
    }
    static void Main(string[] args)
    {
        double result = 0;

        //Method with integer arguments
        result = Sum(10, 20);
        Console.WriteLine("Sum : " + result);

        //Method with integer and float arguments
        result = Sum(10, 20.24F);
        Console.WriteLine("Sum : " + result);

        //Method with integer and double arguments
        result = Sum(10, 27.38);
        Console.WriteLine("Sum : " + result);
    }
}

Output

Sum : 30
Sum : 30.2399997711182
Sum : 37.38
Press any key to continue . . .

Explanation

In the above program, we created a class MethodOver, here we overloaded the sum() method based on the type of arguments to calculate the sum of given arguments.

Here, we created the three methods to calculate the sum of given arguments and return the result to the calling method.

Now look to the Main() method. Here we created the local variable result and then called each overloaded method one by one and printed the result on the console screen.
