DateTimeFormatInfo.NativeCalendarName 属性

定义

命名空间:

System.Globalization

程序集:

System.Runtime.dll

Source:

DateTimeFormatInfo.cs

获取与当前 DateTimeFormatInfo 对象关联的本机日历名称。

public:
 property System::String ^ NativeCalendarName { System::String ^ get(); };

public string NativeCalendarName { get; }

member this.NativeCalendarName : string

Public ReadOnly Property NativeCalendarName As String

属性值

String

在与当前 DateTimeFormatInfo 对象关联的区域性中，如果所用日历的本地名称可用，则为该名称；如果该本地日历名称不可用，则为空字符串 ("")。

示例

以下示例演示了几种方法和属性，这些方法和属性指定日期和时间格式模式、本机日历名称以及完整和缩写的月和日名称。

调用方说明

如果 Calendar 是 ，但 CurrentCulture 不是“zh-TW”，则 NativeCalendarName、 GetEraName(Int32)和 GetAbbreviatedEraName(Int32) 返回空字符串 (TaiwanCalendar“”) 。
