获取仅出现一次的所有元素

Question

使用LINQ,我可以得到只出现一次的所有int元素的列表吗？

例如

{1,2,4,8,6,3,4,8,8,2}

会成为

{1,6,3}

谢谢!

Answer 1

var result =
    from x in xs
    group xs by x into grp
    where grp.Count() == 1
    select grp.Key;

像那样？

Answer 2

list.GroupBy(i => i)
    .Where(g => g.Count() == 1)
    .Select(g => g.First());
