NeutralResourcesLanguageAttribute 类
向 ResourceManager 通知程序集的非特定区域性。无法继承此类。
**命名空间:**System.Resources
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<ComVisibleAttribute(True)> _
<AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple:=False)> _
Public NotInheritable Class NeutralResourcesLanguageAttribute
Inherits Attribute
用法
Dim instance As NeutralResourcesLanguageAttribute
[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple=false)]
public sealed class NeutralResourcesLanguageAttribute : Attribute
[ComVisibleAttribute(true)]
[AttributeUsageAttribute(AttributeTargets::Assembly, AllowMultiple=false)]
public ref class NeutralResourcesLanguageAttribute sealed : public Attribute
/** @attribute ComVisibleAttribute(true) */
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple=false) */
public final class NeutralResourcesLanguageAttribute extends Attribute
ComVisibleAttribute(true)
AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple=false)
public final class NeutralResourcesLanguageAttribute extends Attribute
备注
NeutralResourcesLanguageAttribute 通知用于编写程序集非特定区域性资源的语言的 ResourceManager，还可以通知通过资源后备进程检索非特定区域性资源时，要使用的程序集（主程序集或附属程序集）的 ResourceManager。如果要查找的资源的区域性与非特定资源语言相同，ResourceManager 将自动使用位于主程序集中的资源，而不会根据当前进程的当前用户界面区域性来搜索附属程序集。这将提高对您加载的第一个资源的查找性能，并且可以减少您的工作集。
提示
将此属性应用于您的主程序集，并传递给它将用于您的主程序集的非特定语言的名称。或者，可以传递 UltimateResourceFallbackLocation 枚举的一个成员，以指示检索后备资源的位置。强烈建议使用此属性。
