Hello, you can use Guid to generate uniq id, string uniqueId = Guid.NewGuid().ToString(); OR string uniqueID = string.Format("{0}{1}", Guid.NewGuid().ToString("N").Substring(0, 5), DateTime.Now.ToString("yyyyMMddHHmmssfff")); // uniqueID will be a 19 character alphanumeric string, like: // "3cd3a202108091313432"
