ASP C# Time code

Question

Hello I'm trying to make a stopwatch. I've used a code from the internet to count the minutes and seconds: This is the code( works fine)

    public partial class Ingelogd2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

if (!IsPostBack)
            {
                sw = new Stopwatch();
                sw.Start();
            }
}



private static Stopwatch sw;
    protected void tm1_Tick(object sender, EventArgs e)
    {
        long sec = sw.Elapsed.Seconds;
        long min = sw.Elapsed.Minutes;

    if (min < 60)
        {
            if (min < 10)
               Henkie.Text = "0" + min;
            else
                Henkie.Text = min.ToString();

                Henkie.Text += " : ";

            if (sec < 10)
                Henkie.Text += "0" + sec;
            else
                Henkie.Text += sec.ToString();
        }
        }
        else
        {
            sw.Stop();
            Response.Redirect("Ingelogd2.aspx");
        }
    }
} 
}

The result I'm getting from this code is for example: 00:14 ( after 14 seconds displayed on the label "Henkie")

Now I've tried to add hours aswell, so I've made this code:

    public partial class Ingelogd2 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

if (!IsPostBack)
            {
                sw = new Stopwatch();
                sw.Start();
            }
}


    private static Stopwatch sw;
    protected void tm1_Tick(object sender, EventArgs e)
    {
        long sec = sw.Elapsed.Seconds;
        long min = sw.Elapsed.Minutes;
        long hour = sw.Elapsed.Hours;
        long day = sw.Elapsed.Days;

        if (day < 1)
        {
            if (hour < 10)
                Henkie.Text = "0" + hour;
            else 
                Henkie.Text = hour.ToString();

                Henkie.Text += " : ";
            if (min < 10)
               Henkie.Text = "0" + min;
            else
                Henkie.Text = min.ToString();

                Henkie.Text += " : ";

            if (sec < 10)
                Henkie.Text += "0" + sec;
            else
                Henkie.Text += sec.ToString();
        }
        else
        {
            sw.Stop();
            Response.Redirect("Ingelogd2.aspx");
        }
    }
} 
}

I wanted so it would display for example (00:12:16 after 0 hours, 12 minutes, 16 seconds) but I't doesnt work. It only displays 12:16 after 0 hours, 12 minutes, 16 seconds. I have no idea why this doesn't work. Can somebody help me out?

Answer 1

I have one question for you, which I'd love you to answer before you go on and read the actual solution.

Why are you doing all that? All that code I mean. All that manipulations, adding zeroes, all those if-else statements.

The real question is why complicate something simple?

Now your answer. Just display the Elapsed property. This will internally call the ToString with the c format, which will display hh:mm:ss with optional days if present.

And if you want to omit, let's say, the hours in the first example you still don't need to write all that code, you just:

sw.Elapsed.ToString("mm\\:ss")
