Answer 1

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.

Answer 2

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
