How To FTP Upload a file

This irritated me for a few hours since documentation on the web is quite horrible. Here is how to perform a basic FTP upload with a .NET console application:

 Imports System
 Imports System.Text
 Imports System.Net
 Imports System.IO
 
 Module Module1
 
     Sub Main()
         Dim server As String = "127.0.0.1"
         Dim username As String = "foo"
         Dim password As String = "bar"
         Dim port As Integer = 21
         Dim targetFolder As String = "wwwroot"
         Dim fileName As String = "C:\test.txt"
         Dim passive As Boolean = False
 
         Dim url As String = String.Format("ftp://{0}:{1}/{2}/{3}", server, port, targetFolder, fileName.Substring(fileName.LastIndexOf("\") + 1)) ' make sure you specify the filename and not the entire path or it will thrrow
         Dim FTP As FtpWebRequest = CType(WebRequest.Create(url), FtpWebRequest)
 
         With FTP
             .Credentials = New NetworkCredential(username, password)
             .KeepAlive = False
             .UseBinary = False
             .Method = WebRequestMethods.Ftp.UploadFile
             .UsePassive = passive
 
             Try
                 Using Writer As New BinaryWriter(.GetRequestStream())
                     Writer.Write(File.ReadAllBytes(fileName))
                 End Using
             Catch ex As WebException
                 Throw ex
             Finally
 
             End Try
 
         End With
     End Sub
 End Module
 

Probably the most important thing to remember is that the filename is used in two places. first its used to find where on your computer the file you want to upload is located at. Second you have to be sure to strip out that full path before you put it in the url variable so you have a proper file name on the server.
