# DateTimeOffset.GreaterThanOrEqual(DateTimeOffset, DateTimeOffset) 运算符

## 定义

``````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

right
DateTimeOffset

## 注解

GreaterThan 方法为 DateTimeOffset 对象定义大于或等于运算符的运算。The GreaterThan method defines the operation of the greater than or equal to operator for DateTimeOffset objects. 它可以实现如下所示的代码：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
``````
``````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
``````

``````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
``````

``````return left.UtcDateTime >= right.UtcDateTime;
``````
``````Return left.UtcDateTime >= right.UtcDateTime
``````

The equivalent method for this operator is DateTimeOffset.Compare(DateTimeOffset, DateTimeOffset)
