DateTimeOffset.GreaterThanOrEqual Operator

Determines whether one specified DateTimeOffset object is greater than or equal to 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 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 the same as or later than the UtcDateTime value of right; otherwise, false.

The GreaterThan method defines the operation of the greater 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;
outputBlock.Text += (date1 >= date2) + "\n";        // Displays False
outputBlock.Text += (date1 >= date3) + "\n";        // Displays True 
outputBlock.Text += (date1 >= date4) + "\n";        // Displays True 


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


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(-7, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
             New TimeSpan(-6, 0, 0))
Dim date4 As DateTimeOffset = date1
outputBlock.Text += _
    DateTimeOffset.op_GreaterThanOrEqual(date1, date2).ToString()   ' Displays False & vbCrLf
outputBlock.Text += _
    DateTimeOffset.op_GreaterThanOrEqual(date1, date3).ToString()   ' Displays True & vbCrLf
outputBlock.Text += _
    DateTimeOffset.op_GreaterThanOrEqual(date1, date4).ToString()   ' Displays True & vbCrLf


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;
