表示网站或列表内容类型。
继承层次结构
System.Object
Microsoft.SharePoint.SPContentType
命名空间： Microsoft.SharePoint
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
Public NotInheritable Class SPContentType
用法
Dim instance As SPContentType
public sealed class SPContentType
备注
内容类型旨在帮助用户更有意义的方式组织 SharePoint 内容。内容类型是内容的您想要应用于特定类别的设置的可重用集合。内容类型使您能够集中、 可重用的方式来管理元数据和行为的文档或项目的类型。
For more information, see Introduction to Content Types.
示例
下面的示例是一个控制台应用程序创建内容类型，并将其添加到网站内容类型集合。接下来，本示例创建字段 （列），并链接到新的内容类型的字段。最后，该示例创建一个列表，并将新的内容类型添加到列表所属的内容类型集合。
之前运行的应用程序，您需要向项目中添加对Microsoft.Sharepoint.dll的引用。
