Why isn't my TimeSpan.Add() working?

Question

There has to be an easy answer:

var totalTime = TimeSpan.Zero;

foreach (var timesheet in timeSheets)
{
   //assume \"time\" is a correct, positive TimeSpan
         


        

Answer 1

totalTime = totalTime.Add(time)

Answer 2

TimeSpans are value types. Try:

totalTime = totalTime.Add(time)

Answer 3

This is a common mistake. TimeSpan.Add returns a new instance of TimeSpan.
