Examples

The following example shows a console application that uses hash codes to determine if two SPContentTypeId objects are identical.

Imports System
Imports Microsoft.SharePoint

Module Test
   Sub Main()
      Dim x As SPContentTypeId = SPBuiltInContentTypeId.Announcement
      Dim y As SPContentTypeId = web.Lists("Announcements").ContentTypes("Announcement").Id
      Dim z As SPContentTypeId = y.Parent

      Console.WriteLine(y.GetHashCode() = x.GetHashCode())
      Console.WriteLine(z.GetHashCode() = x.GetHashCode())

      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)
      {
         SPContentTypeId x = SPBuiltInContentTypeId.Announcement;
         SPContentTypeId y = web.Lists["Announcements"].ContentTypes["Announcement"].Id;
         SPContentTypeId z = y.Parent;

         Console.WriteLine(y.GetHashCode() == x.GetHashCode());
         Console.WriteLine(z.GetHashCode() == x.GetHashCode());

         Console.Write("\nPress ENTER to continue...");
         Console.ReadLine();
      }
   }
}

The application prints the following output to the console.

False
True

Press ENTER to continue...
