And*_*rew 1 c# list data-structures
我正在尝试比较两个列表,并在每个列表中仅保留每个列表唯一的项目.你能帮忙吗?
我知道怎么做交集,但实际上我需要做相反的事情
//Example
List<String> baseListCopy = new List<String>();
baseListCopy.Add("Test1");
baseListCopy.Add("Test2");
baseListCopy.Add("Test3");
baseListCopy.Add("Test4");
baseListCopy.Add("Test5");
baseListCopy.Add("Test6");
baseListCopy.Add("Test7");
baseListCopy.Add("Test8");
baseListCopy.Add("Test9");
List<String> resultListCopy = new List<String>();
resultListCopy.Add("Test1");
resultListCopy.Add("Test2");
resultListCopy.Add("Test3");
resultListCopy.Add("Test40");
resultListCopy.Add("Test90");
//returns only items that are present on both lists
resultListCopy = baseListCopy.Intersect(resultListCopy, StringComparer.InvariantCultureIgnoreCase).ToList();
//How do I return only items that are unique to that list?

你的问题不清楚.
听起来你想要所有出现在一个列表中的项目(XOR):
a.Union(b).Except(a.Intersect(b))
