) As TimeSpan
public static TimeSpan operator +(
    TimeSpan t1,
    TimeSpan t2
)

An object whose value is the sum of the values of t1 and t2.

The resulting TimeSpan is less than MinValue or greater than MaxValue.

Remarks

The Addition method defines the addition operator for TimeSpan values. It enables code such as the following:

Dim time1 As New TimeSpan(1, 0, 0, 0)   ' TimeSpan equivalent to 1 day.
Dim time2 As New TimeSpan(12, 0, 0)     ' TimeSpan equivalent to 1/2 day.
Dim time3 As TimeSpan = time1 + time2   ' Add the two time spans.

outputBlock.Text += String.Format("  {0,12}{3} +  {1,10}{3}   {4}{3}    {2,10}", _
                  time1, time2, time3, vbCrLf, New String("_"c, 10)) & vbCrLf
' The example displays the following output:
'           1.00:00:00
'        +    12:00:00
'          __________
'           1.12:00:00
TimeSpan time1 = new TimeSpan(1, 0, 0, 0);   // TimeSpan equivalent to 1 day.
TimeSpan time2 = new TimeSpan(12, 0, 0);     // TimeSpan equivalent to 1/2 day.
TimeSpan time3 = time1 + time2;              // Add the two time spans.

outputBlock.Text += String.Format("  {0,12}\n +  {1,10}\n   {3}\n    {2,10}",
                  time1, time2, time3, new String('_', 10)) + "\n";
// The example displays the following output:
//           1.00:00:00
//        +    12:00:00
//          __________
//           1.12:00:00

Languages that do not support custom operators can call the Add method instead.
