1、取出classList中不包含rightClassList中成员，生成新的missingClassList

        private List<FireInfo> classList= new List<FireInfo>();
        private List<FireInfo> rightClassList = new List<FireInfo>();
        private List<FireInfo> missingClassList = new List<FireInfo>();   

        
    //取出缺少的--
   missingClassList = classList.Where(x => !rightClassList.Any(a => x.name == a.name)).ToList();

2、修改List中指定元素的值

  List<PointData> points = rightPoints.Where(x => x.pointTrs.name.Equals(args.transform.name)).ToList();
  points.ForEach((p) =>
  {
      p.pointTime = (int)phaseTime;
      p.pointTrs = args.transform;
      CommonFunc.SetTrs(p.selectIcon, true);
      if (p.selectIcon2)
          CommonFunc.SetTrs(p.selectIcon2, true);
      //截图
      OperationPhoto.Instance.GetOperationPhoto((Texture2D texture2D, string photoStr) =>
      {
          p.photo = UIManager_01.Instance.ShowPhotos(texture2D);
      });
  });

3、List 中Select、Any、Where、GroupBy的应用

    public void CarRunStatisticsInfoRefresh(CarRunStatisticsInfo[] carRunStatisticsInfos)
    {
        // foreach (var carRunStatisticsInfo in carRunStatisticsInfos)
        {

            IEnumerable<Vector2> thisMonthList = carRunStatisticsInfos.Select(e => new Vector2(e.timeVariable, (float)e.taskTimeCountThis));

            List<Vector2> vector2ThisMonthList = new List<Vector2>();
            List<Vector2> vector2LastMonthList = new List<Vector2>();

            carRunStatisticsSeries_ThisMonth.theGraph.xAxis.AxisMaxValue = dateList.daysInMonth;
            carRunStatisticsSeries_ThisMonth.theGraph.xAxis.AxisNumTicks = (int)dateList.daysInMonth + 1;

            if (carRunStatisticsInfos.Select(e => e.taskTimeCountThis).Max() >= carRunStatisticsInfos.Select(e => e.taskTimeCountLast).Max())

            }
            else

4.List 中Select、Exists、Where的应用

  var tempList = rightPoints.Select(r => r.photo).ToList();
  bool isExist = tempList.Exists(t => t == parent);
  Debug.LogFormat("<color=yellow>{0}是否存在：{1}</color>", parent, isExist);
  if (isExist)
  {
      rightCount--;
      List<PointData> pointDatas = rightPoints.Where(x => x.photo == parent).ToList();
      pointDatas.ForEach(p =>
      {
          p.pointTime = 0;
          CommonFunc.SetCollider(p.pointTrs, true);
          CommonFunc.SetTrs(p.selectIcon, false);
          GameObject.Destroy(p.photo);
          p.photo = null;
      });
  }
  else {
      errorCount--;
      errorPoints.Where((val) => val.photo.name == parent.name).ToList().ForEach(e =>
      {
          CommonFunc.SetCollider(e.pointTrs, true);
          CommonFunc.SetTrs(e.selectIcon, false);
          GameObject.Destroy(e.photo);
      });
      //移除指定元素
      errorPoints = errorPoints.Where((val) => val.photo.name != parent.name).ToList();
  }
