c＃类作为HashSet中的键
[英]c# Class as key in HashSet
问题描述
I am using a HashSet where I use instances of classes as keys, that is, the references to them. 
我正在使用HashSet ，其中将类的实例用作键，即对它们的引用。 What I am unsure of, is if the HashSet will compare the references, which would mean every instance would be different, or the actual values contained in the object, which is what I need. 我不确定的是， HashSet是否会比较引用，这意味着每个实例都会不同，或者对象中包含的实际值正是我所需要的。
Does a HashSet compare by value or reference, and if it is the latter, what would be a good way to let it compare by value? HashSet是否按值或引用进行比较，如果是后者， HashSet值比较的一种好方法是什么？

You'll be able to redefine how comparison is done if it doesn't suit your needs. 如果比较不适合您，您将可以重新定义比较方式。
