如何构造OleDbCommand查询，以便可以从一个.MDB中获取表，然后将其替换为另一个.MDB中的表

尝试更换

using (var destCmdB = new OleDbCommandBuilder(destDA)) {     destDA.DeleteCommand = destCmdB.GetDeleteCommand();     destDA.InsertCommand = destCmdB.GetInsertCommand();        }

和

destDA.InsertCommand = new OleDbCommand("INSERT INTO `AdminUsers` (`UserName`, `Password`) VALUES (?, ?)");destDA.DeleteCommand = new OleDbCommand("DELETE FROM `AdminUsers` WHERe (`ID` = ?)");destDA.UpdateCommand = new OldDbCommand("UPDATE `AdminUsers` SET `UserName` = ?, `Password` = ? WHERe (`ID` = ?)");

查询对您的表结构有效的位置。
