private void button1_Click(object sender, EventArgs e)
        {
             string connectionstring = "Data Source=LQ;Initial Catalog=count;Integrated Security=True";
            SqlConnection con = new SqlConnection(connectionstring);
            SqlCommand sqlcom = new SqlCommand("sp_login", con); //sp_login存储过程
             = CommandType.StoredProcedure;
            sqlcom.Parameters.Add("@userId",SqlDbType.VarChar,8).Value=11;
            sqlcom.Parameters.Add("userPassWord",SqlDbType.VarChar,8).Value=11;
            con.Open();

            SqlDataAdapter custDA = new SqlDataAdapter(sqlcom);

            DataSet custDS = new DataSet();
            custDA.Fill(custDS, "login");
            datagridview1.DataSource = custDS;
            con.Close();
        }
为什么没有反映。这样不能在DataGridView1中显示我要查找的结果吗？？//不可以应该怎么改。

datagridview1.DataSource = custDS.Tables[0].DefaultView;

LS正解~
