排序和非唯一键 [英] Sorting and non-unique keys

问题描述

大家好，


我有一个包含各种属性的集合（比如

字符串，DateTime和Timespan）。我想在应用程序的不同点以各种顺序访问集合

，即有时我想要在日期时间顺序中循环遍历集合中的值

而在TimeSpan订单的其他时间。


理想情况下我想要多个键 - 例如DateTime中的Timespan

订单但也许是要求太多。


我想要使用的一些按键并不是唯一的。


所以我想我有三个问题


1.什么是一般收集整个系列的最佳方式

2.无论如何要用多个键排序

3有什么办法可以用非独特的钥匙进行排序


非常感谢你们给我的任何信息。


问候，


加里

解决方案

不要只有一个数据集合，

但另外，你可以对几个关键的收藏品进行排序并提供对数据收集的访问权限吗？


Adrian。

Gary，


你可以使用一个排序列表。


如果你有更多的钥匙，你可以创建铁道部e以某种方式，即

持有数据，而其他人持有关键

值对中对该数据的引用。

但是排序列表需要一个唯一的密钥吗？


非唯一键的任何选项？

Gary，


您可以使用已排序的列表。


如果您有更多的密钥，您可以创建更多的密钥，其中有一个

保存数据，其他人在关键的

价值对中持有对那一个的引用。

嗨大家好，

我有一个包含各种属性的集合（像
$ b $这样的东西b strings，DateTime和Timespan）。我想在应用程序的不同点以各种顺序访问集合

，即有时我想要在日期时间顺序中循环遍历集合中的值

而在TimeSpan订单的其他时间。

理想情况下，我想要多个键 - 例如DateTime中的Timespan

顺序，但可能是要求太多。

我想要使用的一些键也不是唯一的。

所以我想我有三个问题

1. Whats对一般集合进行分类的最佳方法

2.无论如何都要用多个键排序

3.有没有办法用非唯一键进行排序

非常感谢你们给我的任何信息。

问候，

Gary

Hi Guys,

I have a collection that contains various attributes (stuff like
strings, DateTime and Timespan) . I would like to access the collection
in various orders at different points in the application ie sometimes I
want to cycle through the values in the collection in DateTime order
while at other times in TimeSpan order.

Ideally I would like multiple keys - such as Timespan within DateTime
order but maybe that is asking too much.

Also some of the keys I would like to use are not unique.

So I guess I have three questions

1. Whats the best way of sorting a collection in general
2. Is there anyway to sort with multiple keys
3. Is there any way to do sorts with non-unique keys

Would really appreciate any info you guys could give me.

Regards,

Gary

Would it be an idea not to have just one data collection,
but to have, in addition, several key collections that you
can sort and that give access to your data collection?

Gary,

You can use a sorted list.

If you have more keys, you can create more in a way that there is one that
holds the data and others which holds the references to that one in the key
value pair.

But a sorted list requires a unique key right?

Any options for non unique keys?
