SharePoint Versioning Algorithm

In my current project I need to implement versioning of the document stored in the SQL Server in the same way as SharePoint. I wrote following C# code to simulate versioning of SharePoint:

    int majorVersion = 0;
  int maxMajorVersion = 2;
  int maxMinorVersion = 20;  // default 511;
  string version = string.Empty;
  int counter = 1;
  int id = 1;
  
  int maxId = 512 * maxMajorVersion;
  
  List<int> lstNxtVersionIds = new List<int>();
  for (int i = 1; i <= maxMajorVersion; i++)
   lstNxtVersionIds.Add(i*512);
  
  for (int i = 1; i<=maxId & id<=maxId; i++)
  {   
   if (counter == maxMinorVersion)
   {
    version = majorVersion.ToString() + "." + counter.ToString();
    Console.WriteLine ("id {0}, version {1}", id, version);
    if (majorVersion < maxMajorVersion)
    {
     majorVersion++;
     
     foreach (int nxtVersionId in lstNxtVersionIds)
     {
      if (id < nxtVersionId)
      {
       id = nxtVersionId;       
       break;
      }
     }
    }
    else if (majorVersion == maxMajorVersion)
     break;
    counter = 0;
   }
   version = majorVersion.ToString() + "." + counter.ToString();
   Console.WriteLine ("id {0}, version {1}", id, version);

   id++;
   counter++;
