DateTimeOffset.Equals Method (DateTimeOffset)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Determines whether the current DateTimeOffset object represents the same point in time as a specified DateTimeOffset object.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- other
- Type: System.DateTimeOffset
The object to compare to the current DateTimeOffset object.
Return Value
Type: System.Booleantrue if both DateTimeOffset objects have the same UtcDateTime value; otherwise, false.
Implements
IEquatable(Of T).Equals(T)Before it performs the comparison, this method converts the values of both DateTimeOffset objects to Coordinated Universal Time (UTC). The method is equivalent to the following:
In other words, the Equals(DateTimeOffset) method determines whether two DateTimeOffset objects represent a single point in time. It directly compares neither dates and times nor offsets. To determine whether two DateTimeOffset objects represent the same time and have the same offset value, use the EqualsExact method.
A DateTimeOffset object that is not Nothing is considered to be later (or greater) than one that is Nothing.
This overload of the Equals(DateTimeOffset) method implements the IEquatable(Of T).Equals method. It offers slightly better performance than the DateTimeOffset.Equals(Object) overload because the other parameter does not have to be converted from an object.
The following example illustrates calls to the Equals(DateTimeOffset) method to test DateTimeOffset objects for equality with the current DateTimeOffset object.
Dim firstTime As New DateTimeOffset(#9/1/2007 6:45:00 AM#, _ New TimeSpan(-7, 0, 0)) Dim secondTime As DateTimeOffset = firstTime outputBlock.Text += String.Format("{0} = {1}: {2}", _ firstTime, secondTime, _ firstTime.Equals(secondTime)) + vbCrLf secondTime = New DateTimeOffset(#9/1/2007 6:45:00 AM#, _ New TimeSpan(-6, 0, 0)) outputBlock.Text += String.Format("{0} = {1}: {2}", _ firstTime, secondTime, _ firstTime.Equals(secondTime)) + vbCrLf secondTime = New DateTimeOffset(#9/1/2007 8:45:00 AM#, _ New TimeSpan(-5, 0, 0)) outputBlock.Text += String.Format("{0} = {1}: {2}", _ firstTime, secondTime, _ firstTime.Equals(secondTime)) + vbCrLf ' The example displays the following output: ' 9/1/2007 6:45:00 AM -07:00 = 9/1/2007 6:45:00 AM -07:00: True ' 9/1/2007 6:45:00 AM -07:00 = 9/1/2007 6:45:00 AM -06:00: False ' 9/1/2007 6:45:00 AM -07:00 = 9/1/2007 8:45:00 AM -05:00: True
