DateTimeOffset.LessThanOrEqual Operator

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

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

public static bool operator <=(
	DateTimeOffset left,
	DateTimeOffset right
)

Parameters

left
Type: System.DateTimeOffset

The first DateTimeOffset object.

right
Type: System.DateTimeOffset

The second DateTimeOffset object.

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:

DateTimeOffset date1 = new DateTimeOffset(2007, 6, 3, 14, 45, 0, 
             new TimeSpan(-7, 0, 0));
DateTimeOffset date2 = new DateTimeOffset(2007, 6, 3, 15, 45, 0,
             new TimeSpan(-7, 0, 0));
DateTimeOffset date3 = new DateTimeOffset(date1.DateTime, 
             new TimeSpan(-6, 0, 0));
DateTimeOffset date4 = 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;
