MessageBox.Show(ex.Message.ToString()); }
（2）try
{
SqlCommandBuilder scb = newSqlCommandBuilder(sd); int a = dataGridView1.CurrentRow.Index;
ds.Tables[0].Rows[a].Delete(); sd.Update(ds, \); ds.AcceptChanges(); MessageBox.Show(\删除成功！\); } catch (Exception ex) {
MessageBox.Show(ex.Message.ToString()); }
4，汽车信息管理界面：
添加操作代码：
（1）DAL.CoachDAO coach = new Coach.DAL.CoachDAO(); SqlHelper helper = newSqlHelper();
(2) if (string.IsNullOrEmpty(coachnumber) || string.IsNullOrEmpty(seatnumber1) || string.IsNullOrEmpty(coachholder))
{MessageBox.Show(\车牌号，座位数量，负责人均不能为空！\); } else
{
if (coach.Add(coachtype,coachnumber,date2,seatnumber,ishavetv,ishavecon,coachholder)) MessageBox.Show(\添加成功！\); else
MessageBox.Show(\添加失败！\);
}
（3）实体类CoachDAO.cs中：
publicbool Add(string coachtype,string coachnumber,DateTime date2, int seatnumber,string ishavetv,string ishavecon,string coachholder) {
bool flag = false;
DataTable dt = newDataTable(); string cmdText = \;
SqlParameter[] paras = newSqlParameter[]{ newSqlParameter(\,coachtype),
newSqlParameter(\,coachnumber), newSqlParameter(\,date2),
newSqlParameter(\,seatnumber), newSqlParameter(\,ishavetv), newSqlParameter(\,ishavecon), newSqlParameter(\,coachholder) };
int res = helper.ExecuteNonQuery(cmdText, paras, CommandType.StoredProcedure); if (res > 0)
{
flag = true; } return flag; }
(4)存储过程：
ALTER PROCEDURE dbo.AddCoach @coachtype nvarchar(20), @coachnumber nvarchar(20), @date2 datetime, @seatnumber int, @ishavetv char(10), @ishavecon char(10),
@coachholder nvarchar(20) /* (
@parameter1 int = 5,
@parameter2 datatype OUTPUT ) */ AS
/* SET NOCOUNT ON */ BEGIN
insert into Coach (Ctype,Coachnumber,Ctime,Cnum,Ctv,Ccondition,Coachholder) values (@coachtype,@coachnumber,@date2,@seatnumber,@ishavetv,@ishavecon,@coachholder)
END

as 路程时间 from Line where Lno =\ + lineid + \; dataBind(str1); （3）privatevoid dataBind(string str) { try
{
sd = newSqlDataAdapter(str, conn); ds = newDataSet(); sd.Fill(ds, \);
dataGridView1.DataSource = ds; dataGridView1.DataMember = \; } catch (Exception ex) {
MessageBox.Show(ex.Message); } }
