Assembly: Microsoft.SharePoint (in Microsoft.SharePoint.dll)
'Declaration
Public ReadOnly Property Parent As SPContentTypeId
Get
'Usage
Dim instance As SPContentTypeId
Dim value As SPContentTypeId
value = instance.Parent
public SPContentTypeId Parent { get; }
Type: Microsoft.SharePoint.SPContentTypeId
A content type ID that represents the parent ID.
Content type IDs are designed to be recursive. The ID of a content type encapsulates the lineage of that content type, 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 root of all content type IDs, the System content type ID. By parsing the content type ID, you can determine the lineage of a content type and how two content types are related.
For more information, see Content Type IDs.
Note
The System content type ID is the parent of itself. It is also the parent of the Empty content type ID.
The following example shows a console application that traces the parentage of the ID for the built-in content type named Document.
Imports System
Imports Microsoft.SharePoint
Module ConsoleApp
Sub Main()
Dim child As SPContentTypeId = SPBuiltInContentTypeId.Document
Dim parent As SPContentTypeId = child.Parent
Dim grandparent As SPContentTypeId = parent.Parent
Console.WriteLine(grandparent.ToString())
Console.WriteLine(parent.ToString())
Console.WriteLine(child.ToString())
Console.Write(vbCrLf & "Press ENTER to continue....")
Console.Read()
End Sub
End Module
using System;
using Microsoft.SharePoint;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
SPContentTypeId child = SPBuiltInContentTypeId.Document;
SPContentTypeId parent = child.Parent;
SPContentTypeId grandparent = parent.Parent;
Console.WriteLine(grandparent.ToString());
Console.WriteLine(parent.ToString());
Console.WriteLine(child.ToString());
Console.Write("\nPress ENTER to continue....");
Console.Read();
}
}
}
The application prints the following output to the console.
0x
0x01
0x0101
Press ENTER to continue...
