DateTimeOffset.EqualsExact Method

Determines whether the current DateTimeOffset object represents the same time and has the same offset as a specified DateTimeOffset object.

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

'Declaration
Public Function EqualsExact ( _
	other As DateTimeOffset _
) As Boolean

Parameters

other
Type: System.DateTimeOffset
The object to compare to the current DateTimeOffset object.

Return Value

Type: System.Boolean
true if the current DateTimeOffset object and other have the same date and time value and the same Offset value; otherwise, false.

Because multiple time zones share a single offset, a return value of true does not guarantee that the current and the other object represent times in the same time zone.

Unlike the EqualsExact method, the overloads of the Equals method determine only whether two DateTimeOffset values represent a single point in time. They do not indicate that two values have the same date and time as well as the same offset.

The following example illustrates the use of the EqualsExact method to compare similar DateTimeOffset objects.


Dim instanceTime As New DateTimeOffset(#10/31/2007#, _
                                       DateTimeOffset.Now.Offset)

Dim otherTime As DateTimeOffset = instanceTime
outputBlock.Text += String.Format("{0} = {1}: {2}", _
                  instanceTime, otherTime, _
                  instanceTime.EqualsExact(otherTime)) + vbCrLf

otherTime = New DateTimeOffset(instanceTime.DateTime, _
                               TimeSpan.FromHours(instanceTime.Offset.Hours + 1))
outputBlock.Text += String.Format("{0} = {1}: {2}", _
                  instanceTime, otherTime, _
                  instanceTime.EqualsExact(otherTime)) + vbCrLf

otherTime = New DateTimeOffset(instanceTime.DateTime + TimeSpan.FromHours(1), _
                                TimeSpan.FromHours(instanceTime.Offset.Hours + 1))
outputBlock.Text += String.Format("{0} = {1}: {2}", _
                  instanceTime, otherTime, _
                  instanceTime.EqualsExact(otherTime)) + vbCrLf
' The example produces the following output:
'       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -07:00: True
'       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 12:00:00 AM -06:00: False
'       10/31/2007 12:00:00 AM -07:00 = 10/31/2007 1:00:00 AM -06:00: False
