Question

I have created a windows form application in c# in which input from user is taken .I want to calculate time spent by user in between two submissions.How can I do that?

Answer 1

Use Stopwatch. Create object of the Stopwatch at class level and use that to calculate time.

Something like:

 public partial class Form1 : Form
    {
        Stopwatch stopwatch = new Stopwatch();

        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            stopwatch.Start();

        }
        private void button2_Click(object sender, EventArgs e)
        {

            stopwatch.Stop();
            var milliSeocnds = stopwatch.ElapsedMilliseconds;
            var timeSpan = stopwatch.Elapsed;
        }
    }
