DateTimeOffset.AddMonths() Method in C#

This method is used to return a new DateTimeOffset object that adds a specified number of months to the value of the current instance.

Syntax: public DateTimeOffset AddMonths (int months);
Here, it takes a number of whole months. The number can be negative or positive.

Return Value: This method returns 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.

Exception: This method will give ArgumentOutOfRangeException if the resulting DateTimeOffset value is less than MinValue or the resulting DateTimeOffset value is greater than MaxValue.

            // adding a specified number of whole and
            // fractional months to the value of this
            // instance using AddMonths() method
