c# linq的差集,并集,交集,去重代码(分享)

using System.Linq;  List<string> ListA = new List<string>();List<string> ListB = new List<string>();List<string> ListResult = new List<string>();  ListResult = ListA.Distinct().ToList();//去重ListResult = ListA.Except(ListB).ToList();//差集ListResult= ListA.Union(ListB).ToList(); //并集ListResult = ListA.Intersect(ListB).ToList();//交集
