DateTime.AddMinutes Method

Returns a new DateTime that adds the specified number of minutes to the value of this instance.

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

public DateTime AddMinutes(
	double value
)

Parameters

value
Type: System.Double

A number of whole and fractional minutes. The value parameter can be negative or positive.

Return Value

Type: System.DateTime
An object whose value is the sum of the date and time represented by this instance and the number of minutes represented by value.

ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTime is less than MinValue or greater than MaxValue.

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 fractional part of value is the fractional part of a minute. For example, 4.5 is equivalent to 4 minutes, 30 seconds, 0 milliseconds, and 0 ticks.

The value parameter is rounded to the nearest millisecond.

The following example uses the AddMinutes method to add a number of whole and fractional values to a date and time.

using System;

public class Example
{
   public static void Main()
   {
      DateTime dateValue = new DateTime(2013, 9, 15, 12, 0, 0);

      double[] minutes = { .01667, .08333, .16667, .25, .33333, 
                           .5, .66667, 1, 2, 15, 30, 17, 45, 
                           60, 180, 60 * 24 };

      foreach (double minute in minutes)
         Console.WriteLine("{0} + {1} minute(s) = {2}", dateValue, minute, 
                           dateValue.AddMinutes(minute));
   }
}
