Question

I am currently learning how to work with the stopwatch attribute in C#. I have a button1 that starts the stopwatch. I would like to reset the time to 0 and start over again after the second click and so forth on. How would I be able to reset stopwatch timer after each consecutive button click?

Code

namespace stopwatch
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();    
        }

        Stopwatch sw = new Stopwatch();

        private void button1_Click(object sender, EventArgs e)
        { 
            sw.Start();   
            TimeSpan x = sw.Elapsed;
            textBox1.Text = x.ToString();                   
        }                
    }
}

Answer 1

Use Stopwatch.StartNew()

Try this piece of code snippet instead:

private void button1_Click(object sender, EventArgs e)
{
    sw = Stopwatch.StartNew();

    // ... do something ...

    sw.Stop();

    textBox1.Text = sw.Elapsed.ToString();
}
