array : indexer vs getvalue / setvale

int[] numbers = new int[]{1, 2, 3, 4};
var val1 = numbers.GetValue(3);  // object
var val2 = numbers[3];           // integer

// When you are using Array class(with uppercase) there are no indexers
private void M(Array array) 
{
    array[0] = 5;         // <-- Compiler error
    array.SetValue(5, 0); // <-- Works
}

}
// output: 0, 1, 2
