It sounds like you want to do some event-driven programming. I don't know if you are working in WPF, UWP, or Windows Forms. No matter this video link will help with your problem. https://www.youtube.com/watch?v=yt_rsgFBxzk

If you created a WPF or UWP app, the code would be like this: XAML <TextBlock x:Name="MyTxtBlock" Foreground="Green"/> <Button Click="MyButton_Clicked"/> C# code-behind // Use the intellisense to include // the right namespaces, as I don't // recall them SolidColorBrush MyColors { get { yield return new SolidColorBrush (Colors.Red); yield return new SolidColorBrush (Colors.Blue); yield return new SolidColorBrush (Colors.Green); } } // I can't remember by heart the params // of this event handler, but VS writes it // automatically, so you should have no // problems private void MyButton_Clicked (object sender, EventArgs e) { MyTxtBlock.Foreground = MyColors.Next(); } Note that I'm writing this just by heart, without any testing, so I don't know if it fully works. It should tho. And yet, sorry for the bad indentation, can't do much for that
