ListBox只能绑一列
用DataSet我不会 可以
protected void Button1_Click(object sender, EventArgs e)
{
string strConnection = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=";
strConnection += Server.MapPath("Northwind.mdb");
OleDbConnection objConnection = new OleDbConnection(strConnection);
objConnection.Open();
OleDbCommand OleDbCommand1 = new OleDbCommand();
OleDbCommand1.CommandText = "Select 列名 from 表名";
OleDbCommand1.Connection = objConnection;
ListBox1.DataSource = OleDbCommand1.ExecuteReader();
ListBox1.DataTextField = "列名";
ListBox1.DataBind();

}

DataSet行了
protected void Button1_Click(object sender, EventArgs e)
{
string strConnection = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=";
strConnection += Server.MapPath("Northwind.mdb");
OleDbConnection objConnection = new OleDbConnection(strConnection);
objConnection.Open();
DataSet ds = new DataSet();
OleDbDataAdapter da = new OleDbDataAdapter("select * from 表名", objConnection);
da.Fill(ds, "score");
ListBox1.DataSource = ds.Tables["表名"];
ListBox1.DataTextField = "列名";//关键
ListBox1.DataBind();
objConnection.Close();

}
