语法

声明
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel:=True)> _
Public NotInheritable Class Category
用法
Dim instance As Category

[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel=true)] 
public sealed class Category

备注

In the 企业级搜索 schema, crawled properties are grouped into different categories, representing the protocol handler used. For more information about crawled properties, see 管理元数据.

Use the AllCategories property of the Schema class to get the collection of property categories in the Shared Service Provider's search schema.

Use an indexer to return a single managed property from the CategoryCollection object.

For example, assuming the collection is assigned to a variable named categories, use categories[index] in Microsoft Visual C# or categories(index) in Microsoft Visual Basic, where index is a string containing the name of the category or a GUID identifying the property set for the category.

示例

The following code example writes out the full list of categories to the console window.

Prerequisites

Ensure a Shared Service Provider is already created.
