Solution 2

Try:

C#

Guid g = Guid.NewGuid();

Alternatively, you could allow SQL to generate them by using an Identity field in the DB.

Solution 1

You don't. You let the database create the ID for you.

You can use GUID to create a unique identifier to use... for further improvement or to cater the length you can mix up the GUID along with regex.

Guid guid = Guid.NewGuid();
string id = guid.ToString().Substring(0, 10);
Regex R1 = new Regex(id);
id = Regex.Replace(id, @"\s|\-|'", "");

the above mentioned code is the combination of GUID & regex, and through which a GUID of length 10 can be created. which will be completely uniqeu all the time..

Hope it will help..
