# DateTimeOffset.GreaterThan(DateTimeOffset, DateTimeOffset) 演算子

## 定義

``````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

#### 戻り値

`left`UtcDateTime の値が `right`UtcDateTime の値よりも後の日時を表している場合は `true`。それ以外の場合は `false``true` if the UtcDateTime value of `left` is later than the UtcDateTime value of `right`; otherwise, `false`.

## 注釈

GreaterThan メソッドは、DateTimeOffset オブジェクトの大なり演算子の演算を定義します。The GreaterThan method defines the operation of the greater than operator for DateTimeOffset objects. 次のようなコードが有効になります。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(-6, 0, 0));
DateTimeOffset date3 = new DateTimeOffset(date1.DateTime,
new TimeSpan(-6, 0, 0));
Console.WriteLine(date1 > date2);        // Displays False
Console.WriteLine(date1 > date3);        // 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(-6, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
New TimeSpan(-6, 0, 0))
Console.WriteLine(date1 > date2)        ' Displays False
Console.WriteLine(date1 > date3)        ' Displays True
``````

カスタム演算子をサポートしない言語では、代わりに Compare メソッドを呼び出すことができます。Languages that do not support custom operators can call the Compare method instead. また、次の例に示すように、GreaterThan メソッドを直接呼び出すこともできます。They can also call the GreaterThan 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(-6, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
New TimeSpan(-6, 0, 0))
Console.WriteLine(DateTimeOffset.op_GreaterThan(date1, date2))  ' Displays False
Console.WriteLine(DateTimeOffset.op_GreaterThan(date1, date3))  ' Displays True
``````

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

この演算子の同等のメソッドは DateTimeOffset.Compare(DateTimeOffset, DateTimeOffset)The equivalent method for this operator is DateTimeOffset.Compare(DateTimeOffset, DateTimeOffset)
