Important

Determines whether one specified DateTimeOffset object is greater than or equal to a second specified DateTimeOffset object.
public:
static bool operator >=(DateTimeOffset left, DateTimeOffset right);
public static bool operator >= (DateTimeOffset left, DateTimeOffset right);
static member ( >= ) : DateTimeOffset * DateTimeOffset -> bool
Public Shared Operator >= (left As DateTimeOffset, right As DateTimeOffset) As Boolean
- left
- DateTimeOffset
The first object to compare.
- right
- DateTimeOffset
The second object to compare.
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;
Console.WriteLine(date1 >= date2); // Displays False
Console.WriteLine(date1 >= date3); // Displays True
Console.WriteLine(date1 >= date4); // Displays True
let date1 =
DateTimeOffset(2007, 6, 3, 14, 45, 0, TimeSpan(-7, 0, 0))
let date2 =
DateTimeOffset(2007, 6, 3, 15, 45, 0, TimeSpan(-7, 0, 0))
let date3 =
DateTimeOffset(date1.DateTime, TimeSpan(-6, 0, 0))
let date4 = date1
printfn $"{date1 >= date2}" // Displays False
printfn $"{date1 >= date3}" // Displays True
printfn $"{date1 >= date4}" // Displays True
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 False
Console.WriteLine(date1 >= date3) ' Displays True
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 GreaterThanOrEqual 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_GreaterThanOrEqual(date1, date2)) ' Displays False
Console.WriteLine( _
DateTimeOffset.op_GreaterThanOrEqual(date1, date3)) ' Displays True
Console.WriteLine( _
DateTimeOffset.op_GreaterThanOrEqual(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;
left.UtcDateTime >= right.UtcDateTime
Return left.UtcDateTime >= right.UtcDateTime
The equivalent method for this operator is DateTimeOffset.Compare(DateTimeOffset, DateTimeOffset)
