How can I make a label display how many times a button is hit?

[dejan1]

I have a button and a label. I want to press the button and display on the label the total of the times pressed multiplied by $5.
For example, I press the button 3 times and it displays in the label $15.
Below is what I have so far....

private void button1_Click(object sender, EventArgs e)
{
label1.Text = "0";
int count = System.Convert.ToInt32(label1.Text);
count++;
label1.Text = count.ToString();
}


It displays "1" and allows me to hit the button only once....
