这个问题应该如何解决？

Question

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using HPCIMTS.PublicClass;

namespace HPCIMTS_admin
{
public partial class frmPatienttracking : Form
{
BindingNavigator patientsBindingNavigator = new BindingNavigator();
BindingSource patientsBindingSource = new BindingSource();

    public frmPatienttracking()
    {
        InitializeComponent();
    }

    private void frmPatienttracking_Load(object sender, EventArgs e)
    {
        string connectString = "Data Source=.;Initial Catalog=HPCIMTS;Integrated Security=SSPI";
        SqlConnection connection = new SqlConnection();
        connection.ConnectionString = connectString;
        connection.Open();
        SqlCommand command = new SqlCommand("Select*From vw_病人查询", connection);
        SqlDataReader reader = command.ExecuteReader(CommandBehavior.CloseConnection);
        DataSet ds = new DataSet("HPCIMTS vw_病人查询");
        ds.Load(reader,LoadOption.OverwriteChanges,new string[] { "vw_病人查询" });
        this.txt_Pno.DataBindings.Add(new Binding("Text",this.patientsBindingSource,"病案号",true));
    }
}

}

应该怎么改？

想达到这样的效果：

这是我做的界面

Answer 1

在ds.Load(reader,LoadOption.OverwriteChanges,new string[] { "vw_病人查询" });下一个断点，
然后展开ds
展开里面的tables，看看有没有vw_病人查询
进一步展开，里面的Columns，里面有没有病案号
