Read random txt line, split strings by : and write in textboxes - vb.net

Question

I've got two textboxes and I want make account generator which will read random line from txt file on website and write it into textboxes. So, I want to read random line(just one) from a text file, where email and password are separated by : so .txt file would look like email#site.com:password , write data before : in textbox1(email) and write data from the same line after : in textbox2.
.txt file looks like this:
email1#example.com:password1
email2#example.com:password2
email3#example.com:password3 etc....
I cannot figure out how to split this strings, any help will be appreciated, thanks anyway :)

There you go.
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
tbxEmail.Text = String.Empty
tbxPassword.Text = String.Empty
Dim lines As String() = getData("URL_OF_FILE")
Dim lineCount As Integer = lines.Length
Dim randomValue As Integer = CInt(Math.Floor((lineCount) * Rnd()))
Dim line As String = lines(randomValue)
Dim parts As String() = line.Split(New Char() {":"c})
Dim email As String = parts(0)
Dim password As String = parts(1)
tbxEmail.Text = email
tbxPassword.Text = password
End Sub
Function getData(url As String) As String()
Dim client As System.Net.WebClient = New System.Net.WebClient()
Dim data As String = client.DownloadString(url)
Dim returnValue As String() = data.Split(New String() {Environment.NewLine},
StringSplitOptions.RemoveEmptyEntries)
Return returnValue
End Function
