函数参数 ref int[] 有问题

[cyecp]

    public static void ArrayTest07()
    {
        int[,] a = new int[2, 3];
        a[0, 0] = 1; //ios il2cpp ipad test: invocation exception
        a[0, 0].ToString(); //unityeditor crash on windows pc test

        //下面这里跑不过
        var arr = new int[3];
        Func(ref arr);
        Console.WriteLine(arr[1]);
    }

    static void Func(ref int[] arr)
    {
        arr[1] = 2;
    }
