Question

I want to add time values, e.g. 2:00 + 3:00 = 5:00.

How can I do that in ASP.NET using C#?

Answer 1

With TimeSpan

TimeSpan a = new TimeSpan(2, 0, 0);
TimeSpan b = new TimeSpan(3, 0, 0);
TimeSpan c = a + b;

Answer 2

Have a look at TimeSpan.

Answer 3

I would start by looking at the DateTime and TimeSpan structures. Using these types you can pretty easily perform most Date/Time operations.

Specifically look at these methods:

TryParse: Get extract Date/Time information from a string
TimeSpan.Add
DateTime.Add

A simple example would be:

public TimeSpan? AddTime(string time1, string time2)
{
    TimeSpan ts1;
    TimeSpan ts2;

    if (TimeSpan.TryParse(time1, out ts1) &&
        TimeSpan.TryParse(time2, out ts2))
    {
        return ts1.Add(ts2);
    }

    return null;
}
