ResourcesAttribute 类
派生自Object.Attribute并用于指定应该如何本地化属性。
继承层次结构
System.Object
System.Attribute
Microsoft.SharePoint.WebPartPages.ResourcesAttribute
命名空间： Microsoft.SharePoint.WebPartPages
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
<AttributeUsageAttribute(AttributeTargets.Property Or AttributeTargets.Field)> _
<AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level := AspNetHostingPermissionLevel.Minimal)> _
Public NotInheritable Class ResourcesAttribute _
Inherits Attribute
用法
Dim instance As ResourcesAttribute
[AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field)]
[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public sealed class ResourcesAttribute : Attribute
备注
在运行时， CustomPropertyToolPart查找ResourcesAttribute类。如果找到， CustomPropertyToolPart循环ResourcesAttribute中的资源值的LoadResource方法 （必须覆盖此方法）。如果找不到资源， CustomPropertyToolPart用户界面将生成的默认值。否则，使用本地化值构建CustomPropertyToolPart用户界面。Microsoft.NET Framework 将仅为提供本地化值属性标签、 说明和分类标签。不进行本地化的基本属性名称。如果未定义ResourcesAttribute类， CustomPropertyToolPart用户界面将返回到非本地化元数据 （即， CategoryAttribute、 DescriptionAttribute、 FriendlyNameAttribute和属性的内部名称）。
示例
下面的代码示例演示如何本地化自定义属性时CustomPropertyToolPart用户界面中显示。
