TimeSpan.Addition Operator

Adds two specified TimeSpan instances.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

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

Parameters

t1
Type: System.TimeSpan
The first time interval to add.
t2
Type: System.TimeSpan
The second time interval to add.

Return Value

Type: System.TimeSpan
An object whose value is the sum of the values of t1 and t2.

ExceptionCondition
OverflowException

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

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


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