C#事务

//使用事务

OracleConnection myConn = new OracleConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnStrRmesuser"].ToString());
myConn.Open();
OracleCommand myComm = myConn.CreateCommand();
OracleTransaction myTrans = myConn.BeginTransaction();

//初始化Command 的 Transaction 属性，必要的一步
myComm.Transaction = myTrans;

myTrans.Commit();
}

myTrans.Rollback();
}
}
catch (Exception exception)

}
finally
