Question

        int[] arr1 = new int[10];
        int i, n, p = 0, inval;
        Console.Write("\n\nInsert New value in the sorted array :\n");
        Console.Write("-----------------------------------------\n");

        Console.Write("Input the size of array : ");
        n = Convert.ToInt32(Console.ReadLine());
        /* Stored values into the array*/
        Console.Write("Input {0} elements in the array in ascending order:\n", n);
        for (i = 0; i < n; i++)
        {
            Console.Write("element - {0} : ", i);
            arr1[i] = Convert.ToInt32(Console.ReadLine());
        }
        Console.Write("Input the value to be inserted : ");
        inval = Convert.ToInt32(Console.ReadLine());
        Console.Write("The exist array list is :\n ");
        for (i = 0; i < n; i++)
            Console.Write("{0} ", arr1[i]);
        /* Determine the position where the new value will be insert.*/
        for (i = 0; i < n; i++)
            if (inval < arr1[i])
            {
                p = i;
                break;
            }
        /* move all data at right side of the array */
        for (i = n; i >= p; i--)
            arr1[i] = arr1[i - 1];
        /* insert value at the proper position */
        arr1[p] = inval;

        Console.Write("\n\nAfter Insert the list is :\n ");
        for (i = 0; i <= n; i++)
            Console.Write("{0} ", arr1[i]);
        Console.Write("\n");

嗨。我正在练习，并在教程中找到了一个示例。如果我在Array中创建了3个以上的元素并插入其他元素，则会出现错误。但是，如果我创建<= 3个元素并插入，则效果很好。为什么会发生？您能在这种情况下解释一下吗？
