How to create tables to my database using script code

//create DB
                string sqlString = string.Format("USE [master] CREATE DATABASE {0}", dbName);
                SqlConnection conn = new SqlConnection(ConnectionString);
                SqlCommand cmd = new SqlCommand(sqlString, conn);
                bool err = false;
                try
                {
                    conn.Open();
                    int r = cmd.ExecuteNonQuery();
                }
                catch (Exception ex)
                {
                    created = "\nCreate database failed: " + ex.Message;
                    err = true;
                }
                conn.Close();
                if (err) return created;

//delete all GO cmds
                    sr = new StreamReader("CreateTables.sql");
                    readsql = sr.ReadToEnd();
                    
                    Regex regex = new Regex("^GO", RegexOptions.IgnoreCase | RegexOptions.Multiline);
                    string[] SqlLine = regex.Split(readsql);
