C# Method to sum hh:mm data ???

问题

I want a method that will sum data that is string in the format hh:mm (time hours and minutes)

0:15 + 0:15 = 0:30

回答1:

Convert the strings to TimeSpans and then call the .Add method.

TimeSpan s1 = TimeSpan.Parse("0:15");
TimeSpan s2 = TimeSpan.Parse("0:45");

TimeSpan s3 = s1 + s2;

// not tested; should work.
