如何：创建自定义区域性

项目
08/12/2011

更新：2010 年 12 月

.NET Framework 和 Windows 操作系统附带的预定义区域性指定某个国家/地区中使用的语言和日历，以及在对字符串、日期和数字进行格式设置、分析和比较时使用的文本约定。但是，如果预定义的区域性未提供所需信息，则您可以创建自定义区域性。

定义并创建自定义区域性

使用 CultureAndRegionInfoBuilder 对象来定义和命名自定义区域性。自定义区域性可以是全新的区域性、基于现有区域性的新区域性或将替换现有的 .NET Framework 区域性或 Windows 区域设置的区域性。

对于新的区域性，可以通过调用 CultureAndRegionInfoBuilder.LoadDataFromCultureInfo 方法用区域性信息填充 CultureAndRegionInfoBuilder 对象属性，也可以通过调用 CultureAndRegionInfoBuilder.LoadDataFromRegionInfo 方法用区域信息来填充它。对于替换区域性，被替换的区域性的属性会自动填充 CultureAndRegionInfoBuilder 对象的属性。
根据需要修改 CultureAndRegionInfoBuilder 对象的属性。

调用 CultureAndRegionInfoBuilder.Register 方法以注册自定义区域性。在注册过程中，将会执行下列操作：

创建一个 . nlp 文件，其中包含在 CultureAndRegionInfoBuilder 对象中定义的信息。
将 . nlp 文件存储在计算机上的 %windir%\Globalization 系统目录中。这可使区域性信息在计算机上持久保存，即使关闭计算机也不会丢失。您必须具有此计算机上的管理权限，因为 . nlp 文件存储在系统目录中。
准备 .NET Framework，以便在下次请求创建新的自定义区域性时，搜索 %windir%\Globalization 系统目录而不是内部缓存。

警告
如果您没有对要在其上注册自定义区域性的计算机的管理权限，则调用 CultureAndRegionInfoBuilder.Register 方法将引发 UnauthorizedAccessException。可使用反射调用私有方法来满足此要求。有关更多信息，请参见如何：在没有管理特权的情况下保存自定义区域性。

现在，您的自定义区域性与计算机上的任何预定义 .NET Framework 区域性或 Windows 区域设置都具有相同的状态。在对 CultureAndRegionInfoBuilder.Unregister 方法的调用从本地计算机中删除 . nlp 文件之前，自定义区域是可用的。

若要基于自定义区域性实例化 CultureInfo 对象，请在 CultureInfo 类构造函数中指定其名称。

示例

下面的示例使用 CultureAndRegionInfoBuilder 类来定义和注册一个名为 x-en-US-sample 的自定义区域性，然后为该自定义区域性构造一个 CultureInfo 对象。另外，该示例还演示了 CultureAndRegionInfoBuilder 和 CultureInfo 对象的某些相应属性。
