问题描述

我有一个包含重复对象的列表.为了解决这个问题，我需要将List转换为HashSet(在C#中).有人知道吗?

I have a List that has duplicates of objects. To solve that, I need to convert the List into a HashSet (in C#). Does anyone know how?

推荐答案

确保对象的类覆盖Equals和GetHashCode，然后可以将List<T>传递给HashSet<T>

Make sure your object's class overrides Equals and GetHashCode and then you can pass the List<T> to HashSet<T> constructor.

var hashSet = new HashSet<YourType>(yourList);
