Hey coders! Well, I started creating my generator. If you are wondering what is this generator about, is for Steam Keys - Spotify Account Generator.I have got confused with the code. I want to set RadioButton1 once I click it, for example, to bring me the account to TextBox1. I want to be like this for example:

If RadioButton1.Checked Then

        End If

        Dim array As String() = New WebClient().DownloadString("https://pastebin.com/raw/JhcvQVP0").Split(New Char() {vbLf})
        Me.TextBox1.Text = array(New Random().[Next](0, array.Length))

I know it's completely wrong, but I want once I click the RadioButton1 to bring me the accounts. I need only coders and not time wasters <3. Thanks a lot. Sorry for wasting your time but I am not a professional coder .

I don't understand the Question, do you mean just?

If Me.RadioButton1.Checked Then
   Me.TextBox1.Text = "MyRandomContent"
End If
