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
A DateTime 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, a new DateTime is returned whose value is the result of this operation. The Kind property of the returned DateTime object is the same as that of the original DateTime object.

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.

Converting time intervals of less than an hour to a fraction can involve a loss of prevision because the result is a non-terminating repeating decimal. (For example, one minute is 0.016667 of an hour.) If this is problematic, you can use the DateTime.Add method, which enables you to specify more than one kind of time interval in a single method call and eliminates the need to convert time intervals to fractional parts of an hour.
