Create a Matching Game using visual studio

In this tutorial, you build a matching game, where the player must match pairs of hidden icons. You learn how to:
  • Hold objects using a List object.
  • Use a foreach loop in Visual C# or a For Each loop in Visual Basic.
  • Keep track of a form's state using reference variables.
  • Build an event handler that you can use with multiple objects.
  • Make a timer fire exactly once when started.
Copy this code and create project on visual studio and run it.
