The user input values are passed as an argument in SwapValue function where they are swapped using a third variable temp and the swapped output is displayed as shown in the program below.

C# Program to Swap two Numbers using the Third variable

Source Code:

using System;

public class Swap
{
  public static void SwapValue(int a, int b)
  {
    Console.WriteLine("Entered Numbers are: A=" + a.ToString() + " B=" + b.ToString());

   //temporary variable
    var temp = a;
    a = b;
    b = temp;

    //Display
    Console.WriteLine("The Swapped Numbers are: A=" + a.ToString() + " B=" + b.ToString());

  }

  public static void Main(string[] arg)
  {
    Console.WriteLine("Enter the two numbers that you want to swap: ");
    var input = "";

    input = Console.ReadLine();
    var x = int.Parse(input);

    input = Console.ReadLine();
    var y = int.Parse(input);

    SwapValue(x, y);

  }
