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

static let inline (-)
        d1:DateTime * 
        d2:DateTime  : TimeSpan

Parameters

d1
Type: System.DateTime

The date and time value to subtract from (the minuend).

d2
Type: System.DateTime

The date and time value to subtract (the subtrahend).

Return Value

Type: System.TimeSpan
The time interval between d1 and d2; that is, d1 minus d2.

The Subtraction(DateTime, 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.

NoteNote

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

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