how do generate unique alpha numeric random number in asp.net

Here is the super easy way to do that. Following code snippet will give you 8 digit alphanumeric random string.

      Guid g = Guid.NewGuid();

        string random = g.ToString();

        Response.Write(random.Substring(0, 8));

In the 3rd line you can replace 8 with whatever number (10, 12 etc) and then you may find - that you can replace with empty string.

Please "Mark as answer", if this helped.
