AddMonths Method

DateTimeOffset.AddMonths Method

Adds a specified number of months to the current DateTimeOffset object.

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

member AddMonths : 
        months:int -> DateTimeOffset 

Parameters

months
Type: System.Int32
A number of whole months. The number can be negative or positive.

Return Value

Type: System.DateTimeOffset
An object whose value is the sum of the date and time represented by the current DateTimeOffset object and the number of months represented by months.

ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTimeOffset value is less than MinValue.

-or-

The resulting DateTimeOffset value is greater than MaxValue.

Unlike most of the other methods that add a single time interval unit (such as minutes or days) to a date and time value, AddMonths does not enable you to add fractional parts of a month. To add a time that consists of other time units in addition to months to a DateTimeOffset object, use the Add method.

NoteNote

This method returns a new DateTimeOffset object. It does not modify the value of the current object by adding months to its date and time.

The following example uses the AddMonths method to display the start date of each quarter of the year 2007.
