TimeSpan.Add(TimeSpan) TimeSpan.Add(TimeSpan) TimeSpan.Add(TimeSpan) TimeSpan.Add(TimeSpan) Method

Definition

Returns a new TimeSpan object whose value is the sum of the specified TimeSpan object and this instance.

public:
 TimeSpan Add(TimeSpan ts);
public TimeSpan Add (TimeSpan ts);
member this.Add : TimeSpan -> TimeSpan
Public Function Add (ts As TimeSpan) As TimeSpan
Parameters
ts
TimeSpan TimeSpan TimeSpan TimeSpan

The time interval to add.

Returns

A new object that represents the value of this instance plus the value of ts.

Exceptions

Examples

The following example calls the Add method to add each element in an array of time intervals to a base TimeSpan value.

using System;

public class Example
{
   public static void Main()
   {
      TimeSpan baseTimeSpan = new TimeSpan(1, 12, 15, 16);
      // Create an array of timespan intervals.
      TimeSpan[] intervals = { TimeSpan.FromDays(1.5), 
                               TimeSpan.FromHours(1.5), 
                               TimeSpan.FromMinutes(45), 
                               TimeSpan.FromMilliseconds(505),
                               new TimeSpan(1, 17, 32, 20), 
                               new TimeSpan(-8, 30, 0) };
      // Calculate a new time interval by adding each element to the base interval.
      foreach (var interval in intervals)
         Console.WriteLine(@"{0,-10:g} {3} {1,15:%d\:hh\:mm\:ss\.ffff} = {2:%d\:hh\:mm\:ss\.ffff}", 
                           baseTimeSpan, interval, baseTimeSpan.Add(interval), 
                           interval < TimeSpan.Zero ? "-" : "+");
   }
}
// The example displays the following output:
//       1:12:15:16 + 1:12:00:00.0000 = 3:00:15:16.0000
//       1:12:15:16 + 0:01:30:00.0000 = 1:13:45:16.0000
//       1:12:15:16 + 0:00:45:00.0000 = 1:13:00:16.0000
//       1:12:15:16 + 0:00:00:00.5050 = 1:12:15:16.5050
//       1:12:15:16 + 1:17:32:20.0000 = 3:05:47:36.0000
//       1:12:15:16 - 0:07:30:00.0000 = 1:04:45:16.0000

'       1:12:15:16 - 0:07:30:00.0000 = 1:04:45:16.0000

Remarks

The return value must be between TimeSpan.MinValue and TimeSpan.MaxValue; otherwise, an exception is thrown.

The return value is a new TimeSpan; the original TimeSpan is not modified.
