TimeSpan::Add Method
Visual Studio 2010
Namespace:
System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- ts
- Type: System::TimeSpan
The time interval to add.
Return Value
Type: System::TimeSpanA new object that represents the value of this instance plus the value of ts.
| Exception | Condition |
|---|---|
| OverflowException | The resulting TimeSpan is less than TimeSpan::MinValue or greater than TimeSpan::MaxValue. |
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.
The following example creates several pairs of TimeSpan objects and calculates their sum with the Add method.
