DateTimeOffset.Equality Operator
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Determines whether two specified DateTimeOffset objects represent the same point in time.
Assembly: mscorlib (in mscorlib.dll)
'Declaration Public Shared Operator = ( _ left As DateTimeOffset, _ right As DateTimeOffset _ ) As Boolean
Parameters
- left
- Type: System.DateTimeOffset
The first object to compare.
- right
- Type: System.DateTimeOffset
The second object to compare.
Return Value
Type: System.Booleantrue if both DateTimeOffset objects have the same UtcDateTime value; otherwise, false.
The Equality method defines the operation of the equality operator for DateTimeOffset objects. It enables code such as the following:
Dim date1 As New DateTimeOffset(#6/3/2007 2:45:00 PM#, _ New TimeSpan(-7, 0, 0)) Dim date2 As New DateTimeOffset(#6/3/2007 3:45:00 PM#, _ New TimeSpan(-6, 0, 0)) Dim date3 As New DateTimeOffset(date1.DateTime, _ New TimeSpan(-6, 0, 0)) outputBlock.Text &= (date1 = date2) & vbCrLf ' Displays True outputBlock.Text &= (date1 = date3) & vbCrLf ' Displays False
Before evaluating the left and right operands for equality, the operator converts both values to Coordinated Universal Time (UTC). The operation is equivalent to the following:
In other words, the Equality method determines whether the 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.
