用于存储唯一字符串的集合？ [英] Which collection for storing unique strings?

问题描述

我正在寻找一个像 Dictionary（OF Key，Value）的集合，但我实际上不需要键和值。密钥本身就足够了。所以像 Collection（Key）。它不应该接受重复的键。

我在.NET Framework中查找了几个集合，但是找不到我想要的。目前我滥用 Dictionary（OF String，String）并将值设置为 Nothing 。 >

我是否继续滥用字典（OF T，T）？

解决方案

我认为您想要的是 HashSet< T> 。 p>

I'm looking for a collection just like Dictionary(OF Key, Value) but I don't actually need a key and value. Key itself is enough. So something like Collection(Key). It shouldn't accept duplicate keys.

I've looked up couple of collections in .NET Framework but couldn't find what I want. Currently I'm abusing Dictionary(OF String, String) and setting Value as Nothing all the time.

Shall I just continue abusing Dictionary(OF T,T)?

解决方案

I think what you want is a HashSet<T>.
