First we have to check for the records in the database.

Select count(*) from users;

If the number of records is zero. Then ask the user to enter the initial value.
Check whether it is alphanumeric or numeric using RegEx class.

[HTML]
Regex regex = new Regex("^[a-zA-Z]");

string str = "CAN00001";

regex.IsMatch(str);

[/HTML]

and follow the method i described to increment the alphanumeric value.

Thanks,
