DateTimeOffset.Hour 属性

定义

命名空间:

System

程序集:

System.Runtime.dll

程序集:

mscorlib.dll

程序集:

netstandard.dll

获取由当前 DateTimeOffset 对象所表示的时间的小时组成部分。

public:
 property int Hour { int get(); };

public int Hour { get; }

member this.Hour : int

Public ReadOnly Property Hour As Integer

属性值

Int32

当前 DateTimeOffset 对象的小时组成部分。 此属性使用 24 小时制；值介于 0 到 23 之间。

示例

以下示例以三种不同的方式显示对象的小时组件 DateTimeOffset ：

• 通过检索属性的值 Hour 。

• 通过使用“H”格式说明符调用 ToString(String) 方法。

• 通过使用“HH”格式说明符调用 ToString(String) 方法。

DateTimeOffset theTime = new DateTimeOffset(2008, 3, 1, 14, 15, 00,
                                       DateTimeOffset.Now.Offset);
Console.WriteLine("The hour component of {0} is {1}.",
                  theTime, theTime.Hour);

Console.WriteLine("The hour component of {0} is{1}.",
                  theTime, theTime.ToString(" H"));

Console.WriteLine("The hour component of {0} is {1}.",
                  theTime, theTime.ToString("HH"));
// The example produces the following output:
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.

let theTime = DateTimeOffset(2008, 3, 1, 14, 15, 00, DateTimeOffset.Now.Offset)
printfn $"The hour component of {theTime} is {theTime.Hour}."

printfn $"""The hour component of {theTime} is{theTime.ToString " H"}."""

printfn $"The hour component of {theTime} is {theTime:HH}."

// The example produces the following output:
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
//    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.

Dim theTime As New DateTimeOffset(#3/1/2008 2:15PM#, _
                                       DateTimeOffset.Now.Offset)
Console.WriteLine("The hour component of {0} is {1}.", _
                  theTime, theTime.Hour)

Console.WriteLine("The hour component of {0} is{1}.", _
                  theTime, theTime.ToString(" H"))

Console.WriteLine("The hour component of {0} is {1}.", _
                  theTime, theTime.ToString("HH"))
' The example produces the following output:
'    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
'    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.
'    The hour component of 3/1/2008 2:15:00 PM -08:00 is 14.

注解

该 Hour 属性不受该属性的值 Offset 的影响。

还可以通过使用“H”或“HH”自定义格式说明符调用ToString方法来创建对象的小时组件的字符串表示形式DateTimeOffset。
