DateTime::Subtract Method (TimeSpan)

Subtracts the specified duration from this instance.

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

No code example is currently available or this language may not be supported.

Parameters

value
Type: System::TimeSpan
The time interval to subtract.

Return Value

Type: System::DateTime
An object that is equal to the date and time represented by this instance minus the time interval represented by value.

ExceptionCondition
ArgumentOutOfRangeException

The result is less than DateTime::MinValue or greater than DateTime::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.

Ordinarily, the DateTime::Subtract(TimeSpan) method subtracts a TimeSpan object that represents a positive time span and returns a DateTime value that is earlier than the date and time of the current instance. However, if the TimeSpan object represents a negative time span, the DateTime::Subtract(TimeSpan) method returns a DateTime value that is later than the date and time of the current instance.

The DateTime::Subtract(TimeSpan) method allows you to subtract a time interval that consists of more than one unit of time (such as a given number of hours and a given number of minutes). To subtract a single unit of time (such as years, months, or days) from the DateTime instance, you can pass a negative numeric value as a parameter to any of the following methods:

  • AddYears, to subtract a specific number of years from the current date and time instance.

  • AddMonths, to subtract a specific number of months from the current date and time instance.

  • AddDays, to subtract a specific number of days from the current date and time instance.

  • AddHours, to subtract a specific number of hours from the current date and time instance.

  • AddMinutes, to subtract a specific number of minutes from the current date and time instance.

  • AddSeconds, to subtract a specific number of seconds from the current date and time instance.

  • AddMilliseconds, to subtract a specific number of milliseconds from the current date and time instance.

  • AddTicks, to subtract a specific number of ticks from the current date and time instance.

The following example demonstrates the Subtract method and the subtraction operator.
