c#两个LIST对象移除相同的

您可以使用LINQ的Except方法来实现移除相同元素的功能。下面是一个示例代码：

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        List<int> list1 = new List<int> { 1, 2, 3, 4, 5 };
        List<int> list2 = new List<int> { 4, 5, 6, 7, 8 };

        List<int> result = list1.Except(list2).ToList();

        Console.WriteLine("List 1:");
        foreach (int num in list1)
        {
            Console.Write(num + " ");
        }

        Console.WriteLine("\nList 2:");
        foreach (int num in list2)
        {
            Console.Write(num + " ");
        }

        Console.WriteLine("\nResult:");
        foreach (int num in result)
        {
            Console.Write(num + " ");
        }

        Console.ReadLine();
    }
}

输出结果为：

List 1:
1 2 3 4 5
List 2:
4 5 6 7 8
Result:
1 2 3
