一个内置内容类型检索表示标识符 (Id) 的SPContentTypeId对象的类。
继承层次结构
System.Object
Microsoft.SharePoint.SPBuiltInContentTypeId
命名空间： Microsoft.SharePoint
程序集： Microsoft.SharePoint（位于 Microsoft.SharePoint.dll 中）
语法
声明
Public NotInheritable Class SPBuiltInContentTypeId
用法
Dim instance As SPBuiltInContentTypeId
public sealed class SPBuiltInContentTypeId
备注
您可以使用此类以一种类似于您如何使用枚举成员的字段。
示例
下面的示例是一个控制台应用程序来检查内置的"项"内容类型使用在站点集合中的位置。应用程序通过构建包含信息的每次使用内容类型在网站集的SPContentTypeUsage对象的泛型列表开始。然后该函数计算的次数，以用作网站内容类型的内容类型和它用作列表内容类型的次数。结果输出到控制台。
Imports System
Imports System.Collections.Generic
Imports Microsoft.SharePoint
Module ConsoleApp
Sub Main()
Using siteCollection As SPSite = New SPSite("https://localhost")
Using rootWeb As SPWeb = siteCollection.RootWeb
' Get the content type.
Dim contentType As SPContentType = _
rootWeb.AvailableContentTypes(SPBuiltInContentTypeId.Item)
'Get the usage collection.
Dim usages As IList(Of SPContentTypeUsage) = _
SPContentTypeUsage.GetUsages(contentType)
' Count the site and list types.
Dim listTypes As Integer = 0
Dim siteTypes As Integer = 0
For Each usage As SPContentTypeUsage In usages
If usage.IsUrlToList Then
listTypes += 1
Else
siteTypes += 1
End If
Next usage
Console.Write("The content type is inherited by {0} site content types", siteTypes)
Console.WriteLine(" and {0} list content types.", listTypes)
End Using
End Using
Console.Write(vbCrLf + "Press ENTER to continue...")
Console.ReadLine()
End Sub
End Module
using System;
using System.Collections.Generic;
using Microsoft.SharePoint;
namespace Test
{
class ConsoleApp
{
static void Main(string[] args)
{
using (SPSite siteCollection = new SPSite("https://localhost"))
{
using (SPWeb rootWeb = siteCollection.RootWeb)
{
// Get the content type.
SPContentType contentType =
rootWeb.AvailableContentTypes[SPBuiltInContentTypeId.Item];
//Get the usage collection.
IList<SPContentTypeUsage> usages = SPContentTypeUsage.GetUsages(contentType);
// Count the site and list types.
int listTypes = 0;
int siteTypes = 0;
foreach (SPContentTypeUsage usage in usages)
{
if (usage.IsUrlToList)
listTypes++;
else
siteTypes++;
}
Console.Write("The content type is inherited by {0} site content types", siteTypes);
Console.WriteLine(" and {0} list content types.", listTypes);
}
}
Console.Write("\nPress ENTER to continue...");
Console.ReadLine();
}
}
}
对使用工作组网站模板创建一个 Web 站点运行应用程序时，它会输出以下输出到控制台。
The content type is inherited by 33 site content types and 20 list content types.
Press ENTER to continue...
