The following code example illustrates how to use the FtpWebRequest class to download a remote file from an FTP server.

C#:

// Register FtpWebRequest for the specified schema.
WebRequest.RegisterPrefix("ftp://", Atp.Net.FtpWebRequest.Creator);
Console.WriteLine("Sending request...");
// Create a WebRequest for the specified URL.
WebRequest request = WebRequest.Create("ftp://ftp.example.net/pub/myfile.zip");
// Send the WebRequest and waits for a response.
WebResponse response = request.GetResponse();
// Get remote file stream for downloading.
Stream remoteFileStream = response.GetResponseStream();
Stream localFileStream = File.Create("myfile.zip");
// Create a new buffer to download.
byte[] buffer = new byte[1024];
int n;
do
{
   // Read data from the remote file stream.
   n = remoteFileStream.Read(buffer, 0, buffer.Length);
   // Write to the local file stream.
   localFileStream.Write(buffer, 0, n);
} while (n > 0);
Console.WriteLine("Response Received.");
localFileStream.Close();
// Release the resources of the response.
remoteFileStream.Close();

VB.NET:

' Register FtpWebRequest for the specified schema.
WebRequest.RegisterPrefix("ftp://", Atp.Net.FtpWebRequest.Creator)
Console.WriteLine("Sending request...")
' Create a WebRequest for the specified URL.
Dim request As WebRequest = WebRequest.Create("ftp://ftp.example.net/pub/myfile.zip")
' Send the WebRequest and waits for a response.
Dim response As WebResponse = request.GetResponse()
' Get remote file stream for downloading.
Dim remoteFileStream As Stream = response.GetResponseStream()
Dim localFileStream As Stream = File.Create("myfile.zip")
' Create a new buffer to download.
Dim buffer(1023) As Byte
Dim n As Integer
Do
    ' Read data from the remote file stream.
    n = remoteFileStream.Read(buffer, 0, buffer.Length)
    ' Write to the local file stream.
    localFileStream.Write(buffer, 0, n)
Loop While n > 0
Console.WriteLine("Response Received.")
localFileStream.Close()
' Release the resources of the response.
remoteFileStream.Close()
