string firstName = "sudip";
        string lastName = "saha";
        Session["Count"] = 0;
        if (firstName.Length > 3)
          int count=Convert.ToInt32(Session["Count"]);
            Session["Count"] = count;
            str = firstName.Substring(0, 4);
            str = str + "_" + count.ToString().PadLeft(4, '0');

Solution 2


for the count you need to store it somewhere in database.

your code would be something like,
int count = getLastCount() + 1; //// get last inserted integer value.
string str = String.Format("{0}_{1}", TextBox1.Text.SubString(0,4), count.ToString("0000") );

you need code to get last inserted id from database in getLastCount

Hope this will help you,
