How To Make a StopWatch With C#

I just want to ask that if I can make a stopwatch with C# I tried:

        private void button2_Click(object sender, EventArgs e)
    {
        timer1.Start();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        int st = 00;
        int m = 00;

        string stime = "00:00";
        if(st == 60)
        {
            m++;
            st = 00;
        }
        else
        {
            st++;
        }
        if (m == 60)
        {
            m = 00;
        }
        if(st < 10)
        {
            st = 0 + st;
        }
        if(m < 10)
        {
            m = 0 + m;
        }
        stime = m.ToString() + ":" + st.ToString();
        label3.Text = stime;
    }

this but it didn't worked. My timer is setted up and the interval of the timer is 1000ms. Can someone help me?

It looks to me, that you are more likly to make a watch rather than a stopwatch?

If you're making a stopwatch, I think you need a field/property in your class that holds the starting time:

private DateTime _start;
private void button2_Click(object sender, EventArgs e)
{
    _start = DateTime.Now;
    timer1.Start();
}

and then in timer1_Tick you can do:

private void timer1_Tick(object sender, EventArgs e)
{
    TimeSpan duration = DateTime.Now - _start;
    label3.Text = duration.ToString(<some format string>);
}

It seems that your current code in timer1_Tick only has local variables and therefore always will produce the same time? :-)
