你可以使用Enumerable.SequenceEqual。这适用于任何IEnumerable<T>，而不仅仅是数组。

对于某些应用可能更好:

string.Join(",", arr1) == string.Join(",", arr2)

我在视觉工作室做了这个，效果非常好;用简短的此代码逐个索引地比较数组。

private void compareButton_Click(object sender, EventArgs e)
        {
            int[] answer = { 1, 3, 4, 6, 8, 9, 5, 4, 0, 6 };
            int[] exam = { 1, 2, 3, 6, 8, 9, 5, 4, 0, 7 };

            int correctAnswers = 0;
            int wrongAnswers = 0;

            for (int index = 0; index < answer.Length; index++)
            {
                if (answer[index] == exam[index])
                {
                    correctAnswers += 1;
                }
                else
                {
                    wrongAnswers += 1;
                }
            }

            outputLabel.Text = ("The matching numbers are " + correctAnswers +
                "\n" + "The non matching numbers are " + wrongAnswers);
        }

输出将是;匹配的数字是7 不匹配的数字是3

对于。net 4.0及更高版本，您可以通过使用structuralcompare类型比较数组或元组中的元素:

object[] a1 = { "string", 123, true };
object[] a2 = { "string", 123, true };

Console.WriteLine (a1 == a2);        // False (because arrays is reference types)
Console.WriteLine (a1.Equals (a2));  // False (because arrays is reference types)

IStructuralEquatable se1 = a1;
//Next returns True
Console.WriteLine (se1.Equals (a2, StructuralComparisons.StructuralEqualityComparer)); 

也可以使用array1.ToList()。All(x => array2.Contains(x))如果您需要比较顺序不相同的数组

Elementwise比较?是什么

public void Linq78a()
{
 int[] numbers1 = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
 int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
 bool bb = numbers.Zip(numbers1, (a, b) => (a == b)).Any(p => !p);
 if (!bb) Console.WriteLine("Lists are equal (bb)");
   else Console.WriteLine("Lists are not equal (bb)");
}

将(a==b)条件替换为您想在a和b中进行比较的任何内容。

(这结合了来自MSDN开发者Linq的两个例子)
