New to C# - Loop control events

I know C++ but started learning C# yesterday.

In my windows application form I have a button, with a _Click method. I want the program to change between three separate font background colors every time the user clicks the button. When it reaches the 3rd click, the variable 'count' resets to 0 so it starts over at the first color. However, when I run the following program and click the button, it freezes . I know it's an infinite loop within the while loop, but am not sure about the dynamics of C# and .NET, and how I might pause the program after one pass through the while loop, until the button is clicked again. I have a slight idea about what is going on, but not really. Can you help me get this to work or tell me whats wrong?

Code:

---

namespace Fun_with_if_else_statements
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        static int count = 0;
        private void button1_Click(object sender, EventArgs e)
        {
            if (checkBox1.Checked == true)
            {
                while (count <= 2)
                {
                    if (count == 0)
                        label1.BackColor = System.Drawing.Color.Blue;
                    if (count == 1)
                        label1.BackColor = System.Drawing.Color.Orange;
                    if (count == 2)
                        label1.BackColor = System.Drawing.Color.Black;

                    if (count == 2)
                        count = 0;
                    else
                        count++;
                }
            }
            else
            {
                MessageBox.Show("You must check the enable color changing checkbox\nto allow a change in the font background color.");
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            Close();
        }
    }
}

Please forgive my ignorance. I've been doing so many loops in C++ that I added an unnecessary while loop. I removed it, and kept the if statements, and all works well! Thanks though.
