[VB.NET] Find and match string using last 2 characters from input [NUB Question] - Cendrix - Mar 3, 2020

I have two RichTextBoxes, 1 and 2.

RichTextBox1.Text contains a CD Key, example:

SP-GSsdv-xdHXx-BSjFx

RichTextBox2.Text contains a list of CD KEYS, as follows:

SP-pazeF-wAQLv-D7f1T
SP-26KXJ-2zHF0-FXa2h
SP-HcZbE-3LriX-pvwbH
SP-pcp4L-o4NaW-7lTWk
SP-fnNGt-T5zoq-dJBqT
SP-EJJRu-5Gz2X-VRAUY
SP-ROkHN-iCELi-TZXdh
SP-Np4lf-vlrdl-k8sFx - Target key, it is similar ending in Fx (Case Sensitive), but different from the first
SP-7Asff-8785S-SFEig
SP-CbnRy-mTZQA-sykzp

I'm trying make it so when I click a button, it takes the last 2 characters from the Key in RTBox1 ("Fx" in this case),
then it automatically finds/matches a similar CD key ending in the exact same 2 characters from RTBox2 (Case Sensitive)

Basically, it must be case sensitive and keep it's upper or lower / combined characters exactly how it's given in RTBox1.
If it was fX, fx, FX, then it should keep it's case sensitive and find a similar looking one from RTBox2.

Then Msgbox with the resulted / similar looking Key that picked from RichTextBox2 (SP-Np4lf-vlrdl-k8sFx = final result in this case)

Can anyone help me out please? I'm still new to VB.net and learning and I don't how to deal with matching strings / situations yet

Thanks in advance

I have no clue about VB.NET, did some googling so I can post you some snippets at least:

This should work for getting the last two characters of your string

Code 
Dim result As String = result = str.Substring(str.Length - 2)

Now you can just compare that result string to your first key's last 2 characters (use the same method to get the two last characters of that key)

You can just get the full text from your second textbox and split it into an array (or a vector or whatever you guys have in VB) with the newline character as a delimiter. After that just repeat the above steps

I still can't figure it out :\
It might be super easy but I just cannot find anything helpful on Google and so on

Can any experienced VB.NET coder please provide me a full code 0-100 for exactly what I'm looking for in OP ? It is simply too much for me at the moment :|

Will pay $5 BTC as a thank you, so I can learn from it.

Code 
Dim searchFor As String = RichTextBox1.Text.Substring(RichTextBox1.Text.Length - 2)

        For Each line In RichTextBox2.Lines

            If line.Substring(line.Length - 2) = searchFor Then

                RichTextBox3.Text += line & vbNewLine

            End If

        Next

Should be good enough for you to finish the rest or whatever else

Now it looks super easy.

Kindly PM me your BTC address or post it here if you want ✌

Thanks a bunch.
