DateTimeOffset.LessThanOrEqual Operator

Determines whether one specified DateTimeOffset object is less than a second specified DateTimeOffset object.

Namespace:  System
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.Boolean
true if the UtcDateTime value of left is earlier than the UtcDateTime value of right; otherwise, false.

The LessThanOrEqual method defines the operation of the less than or equal to operator for DateTimeOffset objects. It enables code such as the following:


Dim date1 As New DateTimeOffset(#6/3/2007 2:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date2 As New DateTimeOffset(#6/3/2007 3:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
             New TimeSpan(-6, 0, 0))
Dim date4 As DateTimeOffset = date1
Console.WriteLine(date1 <= date2)        ' Displays True
Console.WriteLine(date1 <= date3)        ' Displays False
Console.WriteLine(date1 <= date4)        ' Displays True


Languages that do not support custom operators can call the Compare method instead. Some languages can also call the LessThanOrEqual method directly, as the following example shows.


Dim date1 As New DateTimeOffset(#6/3/2007 2:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date2 As New DateTimeOffset(#6/3/2007 3:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
             New TimeSpan(-6, 0, 0))
Dim date4 As DateTimeOffset = date1
Console.WriteLine(DateTimeOffset.op_LessThanOrEqual(date1, date2))   ' Displays True
Console.WriteLine(DateTimeOffset.op_LessThanOrEqual(date1, date3)) ' Displays False
Console.WriteLine(DateTimeOffset.op_LessThanOrEqual(date1, date4)) ' Displays True


Before evaluating the left and right operands, the operator converts both values to Coordinated Universal Time (UTC). The operation is equivalent to the following:


Return left.UtcDateTime <= right.UtcDateTime
