我有两个列表
List<int> A= new List<int>()
{33,50,30,90,1,4,5,6,66,
};
and
List<int> B=new List<int>()
{50,4,33};
现在我想查找列表A中列表B中不存在的所有元素
答案 0 :(得分:4)
List<int> res = A.Except(B).ToList();
答案 1 :(得分:0)
using System.IO;
using System;
using System.Linq;
using System.Collections.Generic;
class Program
{
static void Main()
{
List<int> A= new List<int>(){33,50,30,90,1,4,5,6,66,};
List<int> B=new List<int>(){50,4,33};
Console.WriteLine("using linq:");
foreach(int i in A.Except(B).ToList())
Console.WriteLine(i);
Console.WriteLine("without using linq:");
foreach(int i in Except(A,B))
Console.WriteLine(i);
}
private static List<int> Except(List<int> A,List<int>B)
{
List<int> c = new List<int>();
foreach(int i in A)
{
if(B.Contains(i))
continue;
else
c.Add(i);
}
return c;
}
}
