请问 datagridview

请教 datagridview
数据库用的是access，一共四列,SEQ,string1，string2，string3

用四列listbox挺简单的

  {string PathDb = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Directory.GetCurrentDirectory()+"\\"+strPath;
  OleDbDataReader dr;
  OleDbConnection conn = new OleDbConnection(PathDb);
  try
  {
   
  conn.Open();
  OleDbCommand cmd = new OleDbCommand( "select * from every",conn);

  cmd.CommandType = CommandType.Text;
  dr = cmd.ExecuteReader();


  while (dr.Read())
  {
   
  {
  listBox1.Items.Add(dr[0].ToString());
  listBox2.Items.Add(dr[1].ToString());
  listBox3.Items.Add(dr[2].ToString());
  listBox4.Items.Add(dr[3].ToString());

  }
  }

  }
  catch(Exception ex)
  {
  MessageBox.Show(ex.Message);
  }
  finally
  {
  conn.Close();
  }
   
  }



问题是，如果换成datagridview，我就懵了....
前后都一样


  while (dr.Read())
  {
   

  //datagridview填充数据
  }



读取这块直接郁闷了



求教高手

[解决办法]

C# code

            while (reader.Read())            {                DataGridViewRow row = dataGridView1.Rows.Add();                row.Cells[0].Value = xxx;                row.Cells[1].Value = xxx;                row.Cells[2].Value = xxx;                row.Cells[3].Value = xxx;            }

之前在 DataGridView 中创建好列，绑定代码
C# code
while (reader.Read()){    int index = dataGridView1.Rows.Add();    for (int i = 0; i < 4; i++)    {        dataGridView1.Rows[index].Cells[i].Value = dr[i].ToString();    }}
