Refer to the following code ：

    Sub Main()
        Dim testarr() As Integer = New Integer() {12, 44, 2, 54, 1, 24, 77, 12, 33}

        Dim copyarr1() As Integer
        copyarr1 = testarr.Clone

        Array.Sort(copyarr1)
        Console.WriteLine(" Sorted array ：")
        For i As Integer = 0 To copyarr1.Length - 1
            Console.Write(copyarr1(i) & " ")
        Next
        Console.WriteLine()

        Console.WriteLine(" Original array ：")
        For i As Integer = 0 To testarr.Length - 1
            Console.Write(testarr(i) & " ")

What about the order from big to small ？ Use Array.Reverse() The method is ok , The code is as follows ： 
 

    Sub Main()
        Dim testarr() As Integer = New Integer() {12, 44, 2, 54, 1, 24, 77, 12, 33}

        Dim copyarr1() As Integer
        copyarr1 = testarr.Clone

        Array.Sort(copyarr1)
        Console.WriteLine(" Sorted array ：")
        For i As Integer = 0 To copyarr1.Length - 1
            Console.Write(copyarr1(i) & " ")
        Next
        Console.WriteLine()

        Dim copyarr2() As Integer
        copyarr2 = testarr.Clone
        Array.Sort(copyarr2)
        Array.Reverse(copyarr2)

        Console.WriteLine(" Sort arrays from large to small ：")
        For i As Integer = 0 To copyarr2.Length - 1
            Console.Write(copyarr2(i) & " ")
        Next
        Console.WriteLine()

        Console.WriteLine(" Original array ：")
        For i As Integer = 0 To testarr.Length - 1
            Console.Write(testarr(i) & " ")
        Next
        Console.WriteLine()

        Console.ReadKey()
   End Sub
