Answer 1

向数据库中添加记录TicketInfo是实体类 ti.TicketInfo_Airport = tbAirport.Text.Trim();
ti.TicketInfo_ArriveCity = tbArriveCity.Text.Trim();
ti.TicketInfo_ArriveTime = Convert.ToDateTime(tbArriveTime.Text.Trim());
ti.TicketInfo_StartTime = Convert.ToDateTime(tbStartTime.Text.Trim());ti.TicketInfo_Company = tbCompany.Text.Trim();
ti.TicketInfo_Price = tbPrice.Text.Trim();
ti.TicketInfo_StartCity = tbStartCity.Text.Trim();
ti.TicketInfo_Num = tbNum.Text.Trim();
ti.TicketInfo_State = DDState.Text.Trim();

添加到数据库中的字段
GetDataHelpInstance.TicketInfo.InsertOnSubmit(ti);调用层判断是否添加成功

夜壶,就是点击按钮添加一条记录.然后显示消息"添加成功".
过程就是实例化一个对象ti,然后赋予各个属性,最后调用ti的 InsertOnSubmit 方法 进行添加.之后显示消息"添加成功"
