Try something like this:

C#

total.text = (double.Parse(date_dif.text) * double.Parse(TxtQuantity.text)).ToString();

Good luck,
Edo

Try this example which is similar to what you needed :

C#

DateTime a = new DateTime(2008, 01, 02, 06, 30, 00);
            DateTime b = new DateTime(2008, 01, 03, 06, 30, 00);
            TimeSpan duration = b - a;
            String result = TimeSpan.FromTicks(duration.Ticks * 5).ToString();

Hope this helps!

Solution 3

thank you very much It works perfectly well

C#

total.text = (double.Parse(date_dif.text) * double.Parse(TxtQuantity.text)).ToString();

However, to add currency to it like $ sign to it

C#

total.text = (double.Parse(date_dif.text) * double.Parse(TxtQuantity.text)).ToString("$" + "0.00");

the result will appear $30.00

thanks
