DateTime.Subtract Method (DateTime)

 

Subtracts the specified date and time from this instance.

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

member Subtract : 
        value:DateTime -> TimeSpan

Parameters

value
Type: System.DateTime

The date and time value to subtract.

Return Value

Type: System.TimeSpan

A time interval that is equal to the date and time represented by this instance minus the date and time represented by value.

Exception Condition
ArgumentOutOfRangeException

The result is less than MinValue or greater than MaxValue.

If the date and time of the current instance is earlier than value, the method returns a TimeSpan object that represents a negative time span. That is, the value of all of its non-zero properties (such as Days or Ticks) is negative.

TheSubtract(DateTime) method does not consider the value of the Kind property of the two DateTime values when performing the subtraction. Before subtracting DateTime objects, ensure that the objects represent times in the same time zone. Otherwise, the result will include the difference between time zones.

System_CAPS_noteNote

The DateTimeOffset.Subtract(DateTimeOffset) method does consider the difference between time zones when performing the subtraction.

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