Update Document ID Prefix Settings Through Code

We faced a scenario where we need to update the prefix for document Id settings for more numbers of site collection in SharePoint Site through code. After some investigation, I figured out the code and thought of sharing it. Here is the code:

Using C# code

• Add the following references.
  
  
  • Microsoft.SharePoint.dll
  • Microsoft.Office.DocumentManagement.dll
    
    
• Add the following namespaces.
  
  
  • Using Microsoft.SharePoint;
  • Using Microsoft.Office.DocumentManagement; 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.Office.DocumentManagement;
namespace ConsoleAppChangeDocPrefix
{
    class Program
    {
        static void Main(string[] args)
        {
            SPSite site = new SPSite("http://serverName:2085/");
            DocumentId.SetDefaultProvider(site);
            DocumentId.EnableAssignment(site, "sivaprefix", true, true, true, false);
            site.Dispose();
        }
    }
}
