private void button1_Click(object sender, EventArgs e)

            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();
        }
