在C#中比较数组的最简单方法

int[] arr1 = { 1, 2, 3, 4, 5 };
int[] arr2 = { 3, 4, 5, 6, 7 };

var unmatched = arr1.Except(arr2);

Console.WriteLine("Unmatched elements: ");
foreach (int item in unmatched)
{
    Console.WriteLine(item);
}

int[] arr1 = { 1, 2, 3, 4, 5 };
int[] arr2 = { 3, 4, 5, 6, 7 };

Array.Sort(arr1);
Array.Sort(arr2);

for (int i = 0; i < arr1.Length; i++)
{
    for (int j = 0; j < arr2.Length; j++)
    {
        if (arr1[i] == arr2[j])
        {
            Console.WriteLine("Match found at index " + i + " and " + j);
            return;
        }
    }
}

Console.WriteLine("No match found");
