示例
下面的示例是一个检查的内置Announcement内容类型继承的控制台应用程序。该示例获取对内容类型的引用，使用该引用来获取对其父内容类型的引用并使用该引用 （在本例中为System） 获取对的父对象的父内容类型的引用。应用程序然后递减层次结构，打印到控制台的每个内容类型Name和Id属性的值。
Imports System
Imports Microsoft.SharePoint
Module ConsoleApp
Sub Main()
Console.WriteLine()
Dim oSPSite As SPSite = New SPSite("https://localhost")
Dim oSPWeb As SPWeb = oSPSite.OpenWeb()
Dim child As SPContentType = oSPWeb.AvailableContentTypes(SPBuiltInContentTypeId.Announcement)
Dim parent As SPContentType = child.Parent
Dim grandparent As SPContentType = parent.Parent
Console.WriteLine(grandparent.Name + " " + grandparent.Id.ToString())
Console.WriteLine(parent.Name + " " + parent.Id.ToString())
Console.WriteLine(child.Name + " " + child.Id.ToString())
oSPWeb.Dispose()
oSPSite.Dispose()
Console.WriteLine()
Console.Write("Press ENTER to continue...")
Console.ReadLine()
End Sub
End Module
using System;
using Microsoft.SharePoint;
namespace Test
{
class ConsoleApp
{
static void Main(string[] args)
{
Console.WriteLine();
SPSite oSPSite = new SPSite("https://localhost");
SPWeb oSPWeb = oSPSite.OpenWeb();
SPContentType child = oSPWeb.AvailableContentTypes[SPBuiltInContentTypeId.Announcement];
SPContentType parent = child.Parent;
SPContentType grandparent = parent.Parent;
Console.WriteLine(grandparent.Name + " " + grandparent.Id.ToString());
Console.WriteLine(parent.Name + " " + parent.Id.ToString());
Console.WriteLine(child.Name + " " + child.Id.ToString());
oSPWeb.Dispose();
oSPSite.Dispose();
Console.WriteLine();
Console.Write("Press ENTER to continue...");
Console.ReadLine();
}
}
}
示例应用程序打印以下输出到控制台。

Item 0x01
Announcement 0x0104
