将列表转换为数组的意外结果[重复]

Question

以下代码输出“February,February,February,February, February”

但是我正在尝试滚动输出过去 6 个月的数据 - 有人可以帮忙吗？

谢谢！

      DateTime EndDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);//The AddDays function is self explanatory although you can have negative numbers in here

          DateTime StartDate = EndDate.AddMonths(-1); //When do you want the meetings to start DateTime.Today will return midnight
          DateTime m = StartDate.AddMonths(-6);

          List<months> monthstore = new List<months>();

          months monthdata = new months();

          while (m < StartDate)
          {
              monthdata.month = m.ToString("MMMM");
              monthstore.Add(monthdata);

              m = m.AddMonths(1);
          }
        var publicationTable = new[] {
    new[] { monthstore.Select(x=> x.month).ToArray()  }

};

放

 months monthdata = new months();

进入循环，你总是在改变同一个对象。 months 是引用类型
