网上有个用opennetcf的例子，不过是c#，你转过来就ok了。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

using OpenNETCF.Net.Ftp;
using System.IO;
using System.Net;

namespace DeviceApplication10
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
NetworkCredential myCredential=new NetworkCredential("baodao","*****");
if (UploadFile("baodao@211.95.73.93:2122", "testPath", "Sunset.jpg", myCredential))
MessageBox.Show("seccess");
}

public static bool UploadFile(string host, string directory, string filePathName, ICredentials credentials)
{

Uri uri = null;

string fileName = Path.GetFileName(filePathName);
//if (directory == null)
uri = new Uri(string.Format(@"ftp://{0}", host));
//else
//uri = new Uri(string.Format(@"ftp://{0}/{1}/", host, directory));
try {
FtpRequestCreator creator = new FtpRequestCreator();
WebRequest.RegisterPrefix("ftp:", creator);
FtpWebRequest ftpWebRequest = (FtpWebRequest)WebRequest.Create(uri);
//WebRequest ftpWebRequest = WebRequest.Create(uri);
//FtpWebRequest ftpWebRequest = new FtpWebRequest(uri);
ftpWebRequest.Credentials = credentials;
// Getting the Request stream

FileStream filestream = new FileStream(filePathName, FileMode.Open);
BinaryReader fileReader = new BinaryReader(filestream);

Stream ftpRequestStream = ftpWebRequest.GetRequestStream();
StreamWriter commandWriter = new StreamWriter(ftpRequestStream);

//StreamReader responseReader = new StreamReader(ftpRequestStream);

// Just ignore the result, but read it.
//String responseString = responseReader.ReadToEnd();

// Open the input file. If the file does not exist, it's an error.

// Create the reader for the local file data.

commandWriter.Write("TYPE I\r\n");
commandWriter.Flush();

String cmd = "stor " + @"\" + directory + @"\" + fileName + "\r\n";

commandWriter.Write(cmd);
commandWriter.Flush(); // We MUST flush before we start reading from both response and request

// Opening the data connection, this must be done before we issue the command.
Stream ftpResponseStream = ftpWebRequest.GetResponse().GetResponseStream();
BinaryWriter dataWriter = new BinaryWriter(ftpResponseStream);

// Prepare to send commands to the server.

// Set transfer type to IMAGE (binary).

// Reading the request output
//responseReader = new StreamReader(ftpRequestStream);
//responseString = responseReader.ReadToEnd();
// Write the command to the request stream.

// Reading the request output
//responseString = responseReader.ReadToEnd();

// Allocate buffer for the data, which will be written in blocks.
int bufsize = 1024;
byte[] buf = new byte[bufsize];
int xcount;
while ((xcount = fileReader.Read(buf, 0, bufsize)) > 0) {
// Send next buffer over the data connection.
dataWriter.Write(buf, 0, xcount);
Array.Clear(buf, 0, bufsize);
}
fileReader.Close();
filestream.Close();
dataWriter.Close();
//responseReader.Close();
return true;
} catch (Exception ex) {
throw ex;
}
}
}
}
