转换列表<list <string>＆gt;字典<list <string>，int＆gt; </list <string> </list <string>

Question

Dictionary<List<string>, int> dictionary = input.GroupBy(x => x).ToDictionary(x => x.Key, x =>x.Count());

这不起作用，我该怎么办？ GroupBy只比较list的引用。那么如何比较list的元素？

输入在List＆lt;列表＆lt;字符串＆gt;＆gt;我需要在字典中。

Answer 1

试试这个

    Dictionary<List<string>, int> dictionary = str.GroupBy(x => x).ToDictionary(x => x.Key, x =>x.Key.Count);

Answer 2

试试这个

Dictionary<string, int> dictionary = input.GroupBy(x => x).ToDictionary(x => x.Key.toString(), x =>x.Count());
