查找类型列表中是否包含类型列表 [英] Find whether a List of type is contained in a List of Lists of type

问题描述

是否有一种LINQ方式来确定是否，例如:

Is there a LINQ way to find out whether, for example:

List<int> micro = new List<int>(){1,2,3,4,5};

在一个

List<List<int>> macro = new List<List<int>>();

?

我可以对宏执行foreach循环，并检查它是否至少包含一个包含所有micro项(macro[0].Contains(1) && macro[0].Contains(2)...)的List，但是还有其他C#方式吗?

I can do a foreach loop on macro and check whether it contains at least one List that has all of micro's items (macro[0].Contains(1) && macro[0].Contains(2)...), but is there a more C# way to do it?

推荐答案

bool exists = macro.Any(x => micro.All(x.Contains));

如果元素的顺序和数量很重要，请使用SequenceEqual

If the order and the number of element is important use SequenceEqual

bool exists = macro.Any(x => x.SequenceEqual(micro));
