Returns a new DateTime that adds the value of the specified TimeSpan to the value of this instance.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Function Add ( _
val As TimeSpan _
) As DateTime
public DateTime Add(
TimeSpan val
)
public:
DateTime Add(
TimeSpan val
)
member Add :
val:TimeSpan -> DateTime
public function Add(
val : TimeSpan
) : DateTime
Parameters
- val
Type: System. . :: . .TimeSpan
A positive or negative time interval.
Return Value
Type: System. . :: . .DateTime
An object whose value is the sum of the date and time represented by this instance and the time interval represented by val.
Remarks
You can use the Add method to add more than one kind of time interval (days, hours, minutes, seconds, or milliseconds) in a single operation. This method's behavior is identical to that of the addition operator. The DateTime structure also supports specialized addition methods (such as AddDays, AddHours, and AddMinutes) for each time interval.
The Add method takes into account leap years and the number of days in a month when performing date arithmetic.
This method does not change the value of this DateTime. Instead, it returns a new DateTime whose value is the result of this operation. The Kind property of the new DateTime instance is the same as that of the current instance.
