DateTimeOffset.AddMilliseconds() Method in C#

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

Syntax: public DateTimeOffset AddMilliseconds (double milliseconds);
Here, it takes a number of whole and fractional milliseconds. 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 whole milliseconds represented by milliseconds.



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

Below programs illustrate the use of DateTimeOffset.AddMilliseconds(Double) Method:

            DateTimeOffset offset = new DateTimeOffset(2007,
                    6, 1, 7, 55, 0, new TimeSpan(-5, 0, 0));
  
            // a number of whole and fractional milliseconds
            // instance using AddMilliseconds() method
            DateTimeOffset value = offset.AddMilliseconds(2000);
  
            // Display the time
            Console.WriteLine("DateTimeOffset is {0}", value);
        }
  
        catch (ArgumentOutOfRangeException e) {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
