Lamda常见用法

    # List的Lamda查询方法
    var dr = tchmaterials.Select(o => { return (o.f_edition1 == item.f_edition1 && o.f_class == item.f_class) ? o : null; }).ToList<Tchmaterial>();

    # 查询后按时间排序该方法待验证
    topicReplyList.Sort(delegate(ETopicReplyInfo m, ETopicReplyInfo n) { return m.P_FloorDesc.CompareTo(n.P_FloorDesc); });    

    # 读取匿名对象中的属性
    var status=  values.GetType().GetProperty("result").GetValue(values, null);

    # Lamda中delegate的用法
    Organizations orgOne = organList.Find(delegate(Organizations org) { return (org.P_UserRoleType == 1); });

    # GroupBy 用法
    List<E2NationalAward> userLottrys = Dal2NationalAward.GetInstance().GetUserLotteryResult(mfgId);
    if (userLottrys != null && userLottrys.Count > 0)
    {
        var result = userLottrys.GroupBy(o => o.PrizesType).Select(p => (new UserAward()
        {
            UserId = mfgId,
            AwardId = p.Key,
            AwardName = GetName(p.Key),
            Count = p.Count(),
            Status = p.Key.Equals(1) ? "待发货" : "已入账单"
        })).ToList();
        return result;
    }

    # 线程池用法
    ReqestParam param = new ReqestParam();
    param.Id = 1;
    param.Name = "wqcb";
    param.Name1 = "123";
    param.Name2 = "rtyu";
    for (int i = 0; i < 10; i++){
        param.Id = i;
        ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadInvoke), param);
    }

    public void ThreadInvoke(object obj){
        ReqestParam p=obj as ReqestParam;
    }
