寻找像哈希表一样的东西，只有KEYS [英] looking for somehting like a hashing table, with only KEYS

问题描述

嗨组，


我需要类似的功能我从哈希表中获取，但没有

值。我需要的是键。这当然否定了对散列的需要，

但是我想知道C＃中是否有一个类。


我需要to：


- 设置键

- 寻找键的存在

- 删除键。


用于此目的的任何东西？


- Ron

Hi group,

I need similar functionality I''m getting from the hashtable, but without the
value .all I need is keys. this of course negates the need for "hashing",
but I wanted to know if there''s a class for that in C#.

I need to:

- Set keys
- look for the existence of keys
- remove keys.

anything for this purpose?

- Ron

推荐答案

我不清楚你想要什么，如果你只想持有一系列价值

（键）那么你可以使用任何收藏。


也许更多细节会有所帮助

Hi,

I''m not clear of what you want, if you just want to hold a series of values
( the "keys" ) then you can use any collection.

Maybe a little more details will be helpful

Ron，


为什么不使用布尔值true，或使用null。当我需要这个功能时，这就是我的b $ b。


如果我不得不猜测，我会说你正在寻找一种预防方法

重复。


希望这会有所帮助。

Ron,

Why not just use a boolean value of "true", or use null. That''s what I
do when I need this functionality.

If I had to guess, I would say you are looking for a way to prevent
duplicates.

Hope this helps.

这很简单。我需要维护一个对象列表。我想搜索对象列表中的
（使用其他对象）并随意删除它们。


有点像使用哈希表，只有没有值得，我不需要那些。

Hi,

It''s really simple. I need to maintain a list of objects. I want to search
of the list of the objects (using other objects) and remove them at will.

sort of like using a hashtable, only without values, I do not need those.
