C# Call By Value

In C#, value-type parameters are that pass a copy of original value to the function rather than reference. It does not modify the original value. A change made in passed value does not alter the actual value. In the following example, we have pass value during function call.

C# Call By Value Example

using System;
namespace CallByValue
{
    class Program
    {
        // User defined function
        public void Show(int val)
        {
             val *= val; // Manipulating value
            Console.WriteLine("Value inside the show function "+val);
            // No return statement
        }
        // Main function, execution entry point of the program
        static void Main(string[] args)
        {
            int val = 50;
            Program program = new Program(); // Creating Object
            Console.WriteLine("Value before calling the function "+val);
            program.Show(val); // Calling Function by passing value          
            Console.WriteLine("Value after calling the function " + val);
        }
    }
}

Output:

Value before calling the function 50
Value inside the show function 2500
Value after calling the function 50
