//1、建立连接

string sAccessConnection = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Documents and SettingsAdministrator.WWW-410ADC78208桌面应用程序.mdb";

//2、打开连接

odcConnection.Open();

//建立SQL查询

OleDbCommand odCommand = odcConnection.CreateCommand();

//3、输入查询语句

odCommand.CommandText = "SELECT table.编号, table.[123], table.[456] FROM [table];";

//建立读取

OleDbDataReader odrReader = odCommand.ExecuteReader();

//查询并显示数据
