Eliminate Duplicate from a Textbox - vb.net

Question

I have Textbox1.Lines (separated by a space)
5 7 10 12 12
7 10 12 13 14
8 10 14 15 19
12 13 14 15 19
21 23 27 29 50
51 53 55 78 80
1 1 7 14 19
2 4 7 8 10
How should I remove duplicates from each line and display something like this:
7 10 12 13 14
8 10 14 15 19
12 13 14 15 19
21 23 27 29 50
51 53 55 78 80
2 4 7 8 10
that is, to remove from the entire line that contains a duplicate number on the same line.
Private Sub BttGamblerInput_Click(sender As Object, e As EventArgs) Handles BttGamblerInput.Click
On Error Resume Next
Dim value As Integer
Dim values As New List(Of String)
For Each strValue As String In TxtGamblerImput.Text.Split(" ".ToCharArray, StringSplitOptions.RemoveEmptyEntries)
If Integer.TryParse(strValue.Trim, value) Then
values.Add(value)
End If
Not worked.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
For Each line In TxtGamblerOutput.Text
Dim originalArray = TxtGamblerOutput.Text.Split(" ".ToCharArray, StringSplitOptions.RemoveEmptyEntries)
Dim checkArray = originalArray.Distinct().ToArray() ' I haven't used this, so check syntax etc when you code it.
If originalArray.Length = checkArray.Length Then
TxtGamblerOutput.Text = checkArray
Else ' <-- perhaps a bonus here?
' Do something with the invalid line
End If
Next line
End Sub
Code 3:
Dim numbers() As Integer = {1, 3, 5, 7, 2, 1, 5, 4, 4, 8}
' get the duplicates
Dim dups As New Dictionary(Of Integer, Integer) ' number, count of number
For i = 0 To numbers.Length - 1
If dups.ContainsKey(numbers(i)) Then
dups(numbers(i)) += 1
Else
dups.Add(numbers(i), 1)
End If
Next
' display them
For Each dup In dups
If dup.Value > 1 Then
Console.WriteLine(dup.Key)
End If
Next
Console.ReadLine()

I haven't coded or tested anything, but you can use the Distinct method from List(of T) and compare the length of the output to the current List. Another approach is to use an ArrayList (c.f. https://stackoverflow.com/a/13428210/9101981 for the bones of getting unique elements).
Pseudo-ish Code using an Array:
for each line in the text input
originalArray = line.Text.Split(" ".ToCharArray, StringSplitOptions.RemoveEmptyEntries)
checkArray = originalArray.Distinct().ToArray() ' I haven't used this, so check syntax etc when you code it.
If originalArray.Length = checkArray.Length then
' Your code here to display the valid line
Else ' <-- perhaps a bonus here?
' Do something with the invalid line
End If
Next line
