Schema 类 (Microsoft.Office.Server.Search.Administration)

Provides access to the property metadata management system for 企业级搜索.

命名空间: Microsoft.Office.Server.Search.Administration
程序集: Microsoft.Office.Server.Search （在 microsoft.office.server.search.dll 中）

语法

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

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

备注

The Schema class is the entry point for managing the 企业级搜索 metadata schema for a Shared Service Provider's search service. To use the Schema object, you must do the following:

1. Add references to your application for the following dlls:

   • Microsoft.SharePoint.dll

   • Microsoft.Office.Server.dll

   • Microsoft.Office.Server.Search.dll

2. Specify the Shared Service Provider for the search service using the SearchContext object. For more information about ways to retrieve the search context, see 如何：返回搜索服务提供程序的搜索上下文.

The following topics contain code samples demonstrating how to use the Schema object model to perform various metadata management tasks programmatically:

如何：检索共享服务提供程序的托管属性

如何：创建托管属性

如何：删除托管属性

如何：为搜索架构中的类别检索已爬网属性

如何：检索映射到托管属性的已爬网属性

如何：将已爬网属性映射到托管属性

示例

The following code example writes out the full list of managed properties to the console window. For a complete, step-by-step walkthrough of this sample code, see 如何：检索共享服务提供程序的托管属性.

Prerequisites

Ensure a Shared Service Provider is already created.
