C# list常用的几个操作 改变list中某个元素的值 替换某一段数据

1、改变list中某个元素的值

    public class tb_SensorRecordModel

    {

        public int ID { get; set; }

        public decimal Value1 { get; set; }

    }

            List<tb_SensorRecordModel> list = new List<tb_SensorRecordModel>();

            list.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            //改变list中某个元素值

            var model = list.Where(c => c.ID == ).FirstOrDefault();

            model.Value1 = ;

            list.ForEach(c =>

            {

                //打印的数据表明 list中的那个元素 确实被改变了

                //知识：引用、地址

                Console.WriteLine($"{c.ID},{c.Value1}");

            });

            Console.Read();

            return;

2、替换某一段数据

            List<tb_SensorRecordModel> list1 = new List<tb_SensorRecordModel>();

            list1.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list1.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list1.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list1.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list1.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            //构造新的一段数据

            List<tb_SensorRecordModel> list2 = new List<tb_SensorRecordModel>();

            list2.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            list2.Add(new tb_SensorRecordModel { ID = , Value1 =  });

            //删除 旧的 那段数据

            list1.RemoveRange(, );

            //将新的 这段数据 插入到 指定位置

            list1.InsertRange(, list2);

            list1.ForEach(c =>

            {

                Console.WriteLine($"{c.ID},{c.Value1}");

            });

            Console.Read();

            return;
