How can I make stopwatch in C# that displays only seconds and milliseconds?

So I want to make a timer that does this: each time I click the button this happens:

0.052

0.521

1.621

2.151

...

But instead of that it goes like this:

0.015

0.032

0.112

0.252

...

This is happening: picture

This code is not correct, I waits a long time until it makes a sec..

int sec = 0, ms = 1;
private void button1_Click(object sender, EventArgs e)
{
    timer1.Start();
    listBox1.Items.Add(label1.Text);
    timer1.Interval = 1;

}

private void timer1_Tick(object sender, EventArgs e)
{
    ms++;
    if (ms >= 1000)
    {
        sec++;
        ms = 0;

    }
    label1.Text = String.Format("{0:0}.{1:000}", sec, ms);
}

You should use a Stopwatch object from the System.Diagnostics namespace of the .Net framework. Like this:

System.Diagnostics.Stopwatch sw = new Stopwatch();

public void button1_Click()
{
    sw.Start;  // start the stopwatch
    // do work
    ...

    sw.Stop;  // stop the stopwatch

    // display stopwatch contents
    label1.Text = string.Format({0}, sw.Elapsed);
}

If you want to see the total time elapsed as total seconds and milliseconds only (no minutes or hours), you can change that final line to:

label1.Text = string.Format({0}, sw.ElapsedMilliseconds / 1000.0)
