DateTime.AddDays Method

.NET Micro Framework 3.0
Adds a specified number of days to the current DateTime object.

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

public DateTime AddDays (
         double val
)

Parameters

val
A specific number of days. Note that the number in the val parameter can be either positive or negative, and it can express partial days as well as whole days.

Return Value

A new DateTime object having a value that represents the sum of the current DateTime object and the specified number of days.

This method does not change the value of the current DateTime object; rather, it returns a new DateTime object.

The fractional part of a day is represented by the fractional part of the val parameter (that is, anything to the right of the decimal point). For example, 4.5 is equivalent to 4 days, 12 hours, 0 minutes, 0 seconds, 0 milliseconds, and 0 ticks. The number in the val parameter is rounded to the nearest tick.

Available in the .NET Micro Framework versions 2.0, 2.5, 3.0, 4.0, 4.1, and 4.2.
