uploading text file with ftp

[**SpAwN**]

hey so my code so far is this

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
   Dim wc As Net.WebClient
        wc.UploadFile([url]ftp://somesite.orgfree.com[/url], "C:\test.txt")As byte()
End sub

I know I am supposed to add the ftp site as a web reference but it says

Default credentials are not supported on an FTP request.
Parameter name: value
