Have the system do a mathmatical computation like 100! (factorial) and use a timer to see how long it took to run and output the time. To make your application useful on faster systems, run a check to see if the time was under 1/5 of a second to increase the size of the factorial. For example if a fast computer was able to do 100! in under 1/5 of a second, have it do 1000! factorial and report back that time instead. Create your own grading scale based off the times. Try to see if your program can guess how fast the machine is, and report back its guess in Mhz based off the results

Just like he said, I am bored and wanted something to do. I am new to C# but this is what I have:
public int factorial(int n)
{
if (n == 1)
return n;
else
return factorial(n - 1) * n;
}
private void Button1_Click(object sender, EventArgs e)
{
int start = DateTime.Now.Millisecond;
label1.Text = (factorial(Convert.ToInt32(textBox1.Text))).ToString();
int end = DateTime.Now.Millisecond;
label3.Text = ("start: " + start.ToString() + " end: " + end.ToString());
}
Would this be right? It always says the start and end time are the same, so how can I fix that?
