    'webrequest'
    Dim rt As String = TextBox1.Text
    Dim wRequest As WebRequest
    Dim WResponse As WebResponse
    Dim SR As StreamReader
    wRequest = FtpWebRequest.Create(rt)
    WResponse = wRequest.GetResponse

http://wantedlink6
http://wantedlink7

Now i want to add every line in the string to listbox instead of textbox
one item for each line

THERE IS ABOUT 400 http://wantedlink

Answer 1

hrefs in your case already contained IEnumerable(Of String). Joining them into one string and then split it again to make it work is weird. Since String.Split() returns array, maybe you only need to project hrefs into array to make .AddRange() to work :

ListBox1.Items.AddRange(hrefs.ToArray())
