有没有办法在 C# 中比较两个列表[关闭]

我通过以下方式比较两个列表：

var listOne = new List<int>{1,2,3,4,5};
var listTwo = new List<int>{1,2,3,4,5,7};
bool isEqual = false;

foreach (var item in listOne)
{
    if(listTwo.Contains(item))
    {
        isEqual = true;
    }
    else
    {
        isEqual = false;
        break;
    }
}

if(listOne.Count == listTwo.Count && isEqual == true)
{
    Console.WriteLine("Equal list");
}
else
{
    Console.WriteLine("Not Equal list");
}

有什么简单的方法可以做到这一点吗？

很简单的方法

    var listOne = new List<int>{1,2,3,4,5};
    var listTwo = new List<int>{1,2,3,4,5,7};

    if (listOne.SequenceEqual(listTwo))
            {
                Console.WriteLine("Equal list");
            }
            else
            {
                Console.WriteLine("Not Equal list");
            }

如果顺序无关紧要，那么解决方案将是

    var listOne = new List<int>{1,2,3,4,5};
    var listTwo = new List<int>{1,2,3,4,5,7};

     if (listOne.OrderBy(m => m).SequenceEqual(listTwo.OrderBy(m => m)))
        {
            Console.WriteLine("Equal list");
        }
        else
        {
            Console.WriteLine("Not Equal list");
        }
