How to remove vb.net Richtextbox lines that not contains specific text?

Hope this helps This code will remove any line from a richtextbox RichTextbox1 that does not contain "Test" on it. Remember to add Imports System.Text.RegularExpressions to the top of your code.
Private Sub RemoveLines()
    Dim lines As New List(Of String)
    lines = RichTextBox1.Lines.ToList
    Dim FilterText = "Test"

    For i As Integer = lines.Count - 1 To 0 Step -1
        If Not Regex.IsMatch(lines(i), FilterText) Then
        End If

    RichTextBox1.Lines = lines.ToArray

End Sub

How to remove empty lines while preserving the formatting of the richtextbox in c#

wish of those help The Golden Rule about RichTextBoxes is to never change the Text directly, once it has any formatting.
To add you use AppendText and to change you need to use the Select, Cut, Copy & Paste.. methods to preserve the formatting!
string needle = "\r\r";  // only one possible cause of empty lines

int p1 = richTextBox1.Find(needle);
while (p1 >= 0)
    richTextBox1.SelectionStart = p1;
    richTextBox1.Select(p1, needle.Length);
    p1 = richTextBox1.Find(needle);

Remove Duplicate Lines from textbox or richtextbox vb.net

Does that help It looks to me like you want to remove repeating lines, and not simply get a list of distinct values (as demonstrated by the presence of the 'b' before the 'd' in the desired output).
If so, you can use code like this:
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim lines As New List(Of String)(TextBox1.Lines)
    For i As Integer = lines.Count - 1 To 1 Step -1
        If lines(i) = lines(i - 1) Then
        End If
    TextBox1.Lines = lines.ToArray
End Sub
