static List<T> GetPageList(Func<T,bool> whereLambda,Func<T,object> orderLambda,int pageSize,int pageIndex) where T:class { EFEntities context=new EFEntities();//实例化上下文 var list=context.Set<T>().where(whereLambda).orderByDescending(orderLambda).Skip((pageIndex-1)*pageSize).Take(pageSize).Select(s=>s); return list.ToList(); } |

int Total_ = 0; rptCate.DataSource = getPageDate<Category, int>(c => new { c.Name, c.CreatedDate, c.CreatedBy }, c => c.Id > 0, c => c.Id, 2, 4, out Total_); rptCate.DataBind(); this.Label1.Text = Total_.ToString(); |
