This blog will show you how you can create a very cool image matching game for the kids, using C#.NET in Windows Application. Thus, for this article, we will create a new Windows Application and design the form, as shown below.

Afterwards, we will add the code, given below, into the form.cs.
  1. using System;
  2. using System.Collections.Generic;
  3. using System.Drawing;
  4. using System.Windows.Forms;
  6. namespace MatchingGame
  7. {
  8. public partial class Form1 : Form
  9. {
  10. Label firstClicked = null;
  11. Label secondClicked = null;
  13. // Use this Random object to choose random icons for the squares.
  14. Random random = new Random();
  16. //Symbol show as image
  17. List<string> icons = new List<string>()
  18. {
  19. "!", "!", "N", "N", ",", ",", "k", "k",
  20. "b", "b", "v", "v", "w", "w", "z", "z"
  21. };

  36. icons.RemoveAt(randomNumber);
