AddMinutes Method

Calendar.AddMinutes Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Returns a DateTime that is the specified number of minutes away from the specified DateTime.

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

'Declaration
Public Overridable Function AddMinutes ( _
	time As DateTime, _
	minutes As Integer _
) As DateTime

Parameters

time
Type: System.DateTime
The DateTime to which to add minutes.
minutes
Type: System.Int32
The number of minutes to add.

Return Value

Type: System.DateTime
The DateTime that results from adding the specified number of minutes to the specified DateTime.

ExceptionCondition
ArgumentException

The resulting DateTime is outside the supported range of this calendar.

ArgumentOutOfRangeException

minutes is outside the supported range of the DateTime return value.

The minutes value is added to the specified DateTime. If minutes is negative, the resulting DateTime is earlier than the specified DateTime.

The day part of the resulting DateTime is affected if the resulting time is outside the day of the specified DateTime. The month part of the resulting DateTime is affected if the resulting day is outside the month of the specified DateTime. The year part of the resulting DateTime is affected if the resulting month is outside the year of the specified DateTime. The era part of the resulting DateTime is affected if the resulting year is outside the era of the specified DateTime.

The Kind property of the returned DateTime value always equals DateTimeKind.Unspecified. You can preserve the Kind property of the time parameter by calling the DateTime.SpecifyKind method, as the following example shows.


returnTime = DateTime.SpecifyKind(cal.AddMinutes(time, minutes), time.Kind)


The following code example demonstrates the members of the Calendar class.
