Welcome to the RingCentral Community

Thanks, works perfectly.

One small error. It should be if (response.paging.totalPages >= pageNumber)

Otherwise entries from last page will not be read.

You can read like this

read_company_directory(-1).Wait();

static private async Task read_company_directory(int pageNumber)
{
  pageNumber++;
  var listDirEntriesParams = new ListDirectoryEntriesParameters();
  listDirEntriesParams.perPage = 300;
  if (pageNumber > 0)
      listDirEntriesParams.page = pageNumber.ToString();
  var response = await rcsdk.Restapi().Account().Directory().Entries().List(listDirEntriesParams);
  Console.WriteLine("Directory");
  Console.WriteLine(JsonConvert.SerializeObject(response.paging));
  if (response.paging.totalPages >= pageNumber)
  {
      read_company_directory(pageNumber).Wait();
  }
}
