c# – 如何按顺序将项目插入列表？

有人可以教我如何在C#中按顺序插入项目到列表中？

我有一个DateTimeOffset对象的列表,我想按顺序插入新的列表.

List<DateTimeOffset> TimeList = ...
// determine the order before insert or add the new item

对不起,需要更新我的问题.

List<customizedClass> ItemList = ...
//customizedClass contains DateTimeOffset object and other strings,int,etc.

ItemList.sort();    // this won't work until set data comparison with DateTimeOffset
ItemList.OrderBy(); // this won't work until set data comparison with DateTimeOffset

有没有人可以帮我把DateTimeOffset作为.OrderBy()的参数？

我也试过

ItemList = from s in ItemList
           orderby s.PublishDate descending    // .PublishDate is type DateTime
           select s;

但是,它返回此错误消息,

Cannot implicitly convert type ‘System.Linq.IOrderedEnumerable’ to ‘System.Collections.Gerneric.List’. An explicit conversion exist (are you missing a cast?)

解决方法

修改LINQ,最后添加ToList()：

ItemList = (from s in ItemList
            orderby s.PublishDate descending   
            select s).ToList();

或者将排序的列表分配给另一个变量

var sortedList = from s in ....
