获取内容类型的统一资源定位器 (URL)。
命名空间： Microsoft.SharePoint
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
Public ReadOnly Property Url As String
Get
用法
Dim instance As SPContentTypeUsage
Dim value As String
value = instance.Url
public string Url { get; }
属性值
类型：System.String
相对于服务器的 URL。
备注
网站内容类型的属性返回网站的相对于服务器的 URL。对于列表内容类型，则Url属性返回的列表的根文件夹的相对于服务器的 URL。
示例
下面的示例演示的控制台应用程序获取内置内容类型Item的使用率集合。应用程序使用的每个SPContentTypeUsage对象的Url属性集合中确定的父内容类型实例的名称。然后应用程序打印的范围 （网站或列表实例的) 实例的名称和到控制台Url属性的值。

应用程序运行时针对网站集的根网站和一个子网站，以此方式打印到控制台以下 (部分) 输出。

This is a site content type.
URL: /
Content type name: Feature Points of Contact
This is a site content type.
URL: /Subsite
Content type name: Task
This is a list content type.
URL: /Lists/Tasks
Content type name: Feature Points of Contact
This is a list content type.
