复制代码 代码如下:

var list = Pt_OrderWorkFlow_DAO.GetOrderWorkFlow(wfid, uid, 1);

if (list == null)

{

list = new List<Pt_OrderWorkFlow>();

}

dgWaitList.DataSource = list;

dgWaitList.DataBind();

可以直接这样比较优雅了

复制代码 代码如下:

OADataContext db = DatabaseHelper.GetDB();

var rs = (from a in db.Pt_OrderWorkFlow

where a.WFID == wfID && a.ContractNumber == cNumber

select a).ToList<Pt_OrderWorkFlow>();

return rs.Count() > 0 ? rs : new List<Pt_OrderWorkFlow>();
