Question

我的代码工作正常，它表示行已保存，但是当我查看数据库时，没有保存行。你能帮帮我吗？

我想使用存储过程保存一行，checkifusernameexist正在运行，但保存功能不保存数据。

这是我的代码，希望你能理解它。

        public string GetConnectionString()
        {
            return System.Configuration.ConfigurationManager.ConnectionStrings["practiceDatabaseConnectionString"].ConnectionString;
        }

        private void executeAdd(string username, string password)
        {
            SqlConnection conn = new SqlConnection(GetConnectionString());
            conn.Open();

            SqlCommand cmd = new SqlCommand("usp_CreateUser", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlParameter p1 = new SqlParameter("userName",userName.Text);
            SqlParameter p2 = new SqlParameter("password",password.ToString());
            cmd.Parameters.Add(p1);
            cmd.Parameters.Add(p2);

            SqlDataReader dReader = cmd.ExecuteReader();

            if (dReader.HasRows)
            {
                dReader.Read();     
                Label3.Text="Record Added!";
            }
            else
            {
                Label3.Text="User Error";
            }
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            SqlConnection con = new SqlConnection(GetConnectionString());
            con.Open();

            cmd.CommandType = CommandType.StoredProcedure;
            SqlParameter p1 = new SqlParameter("userName", userName.Text);
            cmd.Parameters.Add(p1);
            SqlDataReader dReader = cmd.ExecuteReader();

            if (dReader.HasRows)
            {
                dReader.Read();
                this.Label3.ForeColor = System.Drawing.Color.Red;
                this.Label3.Text = "Username already exist!";
            }
            else
            {
                this.Label3.Text = "congrats! nanalo ka na!";
                this.userName.Text = "";
                this.password.Text = "";
            }
        }
    }
}
