[vb.net] Sorting decimal in ascending order in richtextbox

[matty95srk]

I need to sort in ascending numbers the lines of a richtextbox, which got decimals in the follow format:

0.00001302 - 283000
0.00001315 - 295800
0.00001328 - 292600
0.00001333 - 7700
0.00001341 - 308500

I'm trying to sort the lines to obtain an output like:

0.00001341 - 308500
0.00001333 - 7700
0.00001328 - 292600
0.00001315 - 295800
0.00001302 - 283000

Ive tried

RichTextBox1.Lines = RichTextBox1.Lines.OrderBy(Function(x) Decimal.Parse(x)).ToArray

and

Dim lines() As String = RichTextBox1.Lines
        Dim value = lines.Select(Function(x) Convert.ToInt32(x)).OrderByDescending(Function(x) x)
        RichTextBox1.Text = String.Join(Environment.NewLine, value)

but for both I get the same error:

System.FormatException: '"Input string is not in correct format"'

Clearly the sorting doesn't like the format of the lines, so how can I make it to do not care about the format and just caring about the decimals? Thanks
