SPContentType.Id property
Gets an SPContentTypeId object that represents the content type identifier (ID) of the content type.
Namespace: Microsoft.SharePoint
Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
Syntax
'Declaration
Public ReadOnly Property Id As SPContentTypeId
Get
'Usage
Dim instance As SPContentType
Dim value As SPContentTypeId
value = instance.Id
public SPContentTypeId Id { get; }
Property value
Type: Microsoft.SharePoint.SPContentTypeId
The content type ID.
Remarks
Content type IDs identify content types and are designed to be recursive. The content type ID encapsulates that content type's lineage, or the line of parent content types from which the content type inherits. Each content type ID contains the ID of the parent content type, which in turn contains the ID of that content type's parent, and so on, ultimately back to and including the System content type ID. By parsing the content type ID, you can determine which content types the content type inherits, and how two content types are related.
For more information, see Content Type IDs.
Examples
The following example is a console application that searches a site for lists that have the built-in Document content type in their content type collection. When a match is found, the application prints the parent content type ID and the matching content type ID to the console.
Imports System
Imports Microsoft.SharePoint
Module Test
Sub Main()
Using site As SPSite = New SPSite("https://localhost")
Using web As SPWeb = site.OpenWeb()
' Search for a built-in content type on lists in the site.
Dim parentId As SPContentTypeId = SPBuiltInContentTypeId.Document
For Each list As SPList In web.Lists
Dim matchId As SPContentTypeId = _
list.ContentTypes.BestMatch(parentId)
' Report a match only if the list is not hidden
' (e.g. Master Page Gallery).
If parentId.IsParentOf(matchId) And Not list.Hidden Then
Console.WriteLine("{0} has the {1} content type.", _
list.Title, _
list.ContentTypes(matchId).Name)
Console.WriteLine("parent content type id: {0}", _
parentId.ToString())
Console.WriteLine(" list content type id: {0}",_
matchId.ToString())
End If
Next list
End Using
End Using
Console.Write(vbCrLf + "Press ENTER to continue...")
Console.ReadLine()
End Sub
End Module
using System;
using Microsoft.SharePoint;
namespace Test
{
class ConsoleApp
{
static void Main(string[] args)
{
using (SPSite site = new SPSite("https://localhost"))
{
using (SPWeb web = site.OpenWeb())
{
// Search for a built-in content type on lists in the site.
SPContentTypeId parentId = SPBuiltInContentTypeId.Document;
foreach (SPList list in web.Lists)
{
SPContentTypeId matchId =
list.ContentTypes.BestMatch(parentId);
// Report a match only if the list is not hidden
// (e.g. Master Page Gallery).
if (parentId.IsParentOf(matchId) && !list.Hidden)
{
Console.WriteLine("{0} has the {1} content type.",
list.Title,
list.ContentTypes[matchId].Name);
Console.WriteLine("parent content type id: {0}",
parentId.ToString());
Console.WriteLine(" list content type id: {0}",
matchId.ToString());
}
}
}
}
Console.Write("\nPress ENTER to continue...");
Console.ReadLine();
}
}
}
The application prints the following output to the console.
Shared Documents has the Document content type.
parent content type id: 0x0101
list content type id: 0x010100C21DAAD3BCD4FF409A4DB5005BF7E12F
Press ENTER to continue...
