Ordering Textbox Lines Ascending to Descending

I want order descending as ascending my Textbox.Lines.

Textbox1.Lines

13
71
68
101
54

Output: Expecting

101
71
68
54
13

<<<<<<<<<<<<<<<<<<<<<<<

  Dim lines() As String = TextBox1.Lines
        Dim value As New System.Collections.Generic.List(Of Integer)
        For Each line As String In lines
            value.Add(Convert.ToInt32(line))
        Next
        value.Sort()
        TextBox2.Text = value.ToString

Linq:

Dim lines() As String = Textbox1.Lines
Dim value = lines.Select(Function(x) Convert.ToInt32(x)).OrderByDescending(Function(x) x)
Textbox2.Text = value.tostring

So what i'm wrong?

value.ToString will just output the type of the object because an array of integers doesn't know how to print its single elements. You should join together the elements and print the resulting string 

Textbox2.Text = String.Join(Environment.NewLine, value)
