Adds two specified TimeSpan instances.

public:
 static TimeSpan operator +(TimeSpan t1, TimeSpan t2);

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

static member ( + ) : TimeSpan * TimeSpan -> TimeSpan

Public Shared Operator + (t1 As TimeSpan, t2 As TimeSpan) As TimeSpan

Parameters

t1: TimeSpan

The first time interval to add.

t2: TimeSpan

The second time interval to add.

Returns

TimeSpan

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

Exceptions

OverflowException

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

Remarks

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

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.

Console.WriteLine("  {0,12}\n +  {1,10}\n   {3}\n    {2,10}", 
                  time1, time2, time3, new String('_', 10));

// The example displays the following output:
//           1.00:00:00
//        +    12:00:00
//          __________
//           1.12:00:00

open System

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

printfn $"  {time1,12}\n +  {time2,10}\n   {String('_', 10)}\n    {time3,10}" 
// The example displays the following output:
//           1.00:00:00
//        +    12:00:00
//          __________
//           1.12:00:00

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.

Console.WriteLine("  {0,12}{3} +  {1,10}{3}   {4}{3}    {2,10}", _
                  time1, time2, time3, vbCrLf, New String("_"c, 10))
' 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.

The equivalent method for this operator is TimeSpan.Add(TimeSpan)
