二、实现过程
①、房间管理
新增房间
string sql = string.Format(@"insert into RoomTable(RoomID, Floor, TypeID, StateID)
values('{0}','{1}','{2}','{3}')", tbFangHao.Text, tbLouCeng.Text, cbLeiXing.SelectedValue.ToString(), cbZhuangTai.SelectedValue.ToString());
if (db.ExecuteSQLCommand(sql) > 0)
{
string aac = string.Format("{0}房间新增成功！", tbFangHao.Text);
MessageBox.Show(aac);
}激活房卡
string sql = string.Format(@"insert into RoomIDCard(RoomID, RoomCard)
values('{0}','{1}')", FangHao, tbFangKa.Text);
int a = db.ExecuteSQLCommand(sql);
if (a > 0)

}②、房客管理
新增房客
