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
<DefaultMemberAttribute("Item")> _
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel:=True)> _
Public NotInheritable Class CategoryCollection
    Implements IEnumerable
用法
Dim instance As CategoryCollection

[DefaultMemberAttribute("Item")] 
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel=true)] 
public sealed class CategoryCollection : IEnumerable

备注

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

Use an indexer to return a single category 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 that identifies the property set for a category.

Use the Create method of the CategoryCollection class to create a new category in the search schema.

Use the Delete method of the Category class to delete a category in the search schema.

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.
