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)

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)); 

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)

        int[] a = { 2, 1, 3, 4, 5, 2 };

        int[] b = { 2, 1, 3, 4, 5, 2 };

        bool ans = true;

        if(a.Length != b.Length)
        {
            ans = false;
        }
        else
        {
            for (int i = 0; i < a.Length; i++)
            {
                if( a[i] != b[i])
                {
                    ans = false;
                }
            }
        }

        string str = "";

        if(ans == true)
        {
            str = "Two Arrays are Equal";
        }

        if (ans == false)
        {
            str = "Two Arrays are not Equal";
        }

       //--------------Or You can write One line of Code-------------

        var ArrayEquals = a.SequenceEqual(b);   // returns true
