问题描述
我需要找到并从一个元组的列表中删除重复项。 基本上,我的结构是由这样的:
I need to find and remove the duplicates from a List of tuples. Basically, my structure is made like that:
List<Tuple<string, string>> myList = new List<Tuple<string, string>>(); **** private void FillStructure() { myList.Add(Tuple.Create<string, string>("A", "B")); myList.Add(Tuple.Create<string, string>("A", "C")); myList.Add(Tuple.Create<string, string>("C", "B")); myList.Add(Tuple.Create<string, string>("C", "B")); // Duplicate myList.Add(Tuple.Create<string, string>("A", "D")); FindAndRemoveDuplicates(myList); } private void FindAndRemoveDuplicates(List<Tuple<string, string>> myList) { // how can I perform this ? }
我不能使用字典,因为我可以有相同的密钥,但不同值! 预先感谢您
I can't use a Dictionary because I can have the same key but different values! Thank you in advance
推荐答案您可以使用的 鲜明的() LINQ的方法是这样的:
You can use Distinct() method of LINQ, like this:
myList = myList.Distinct().ToList();请注意,这将重新创建列表,而不是代替删除重复项。
Note that this would re-create the list, rather than removing the duplicates in place.
