| I posted the WebClient versions in this Newsgroups.
|
| The FtpWebRequest DownloadFile version is ...
|
|   private byte[] byWork = new byte[2047] ;
|   private int iWork ;
|
|   private void DownloadFile(string strAddress, string strUsername, string
| strPassword )
|    {
|    this.lblStatus.Visible = false ;
|    try
|     {
|     FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create("ftp://" +
| strAddress );
|     req.Credentials = new NetworkCredential(strUsername, strPassword );
|     req.Method = WebRequestMethods.Ftp.DownloadFile ;
|     FtpWebResponse resp = (FtpWebResponse)req.GetResponse( );
|     Stream rs = resp.GetResponseStream( );
|     FileStream fs = new FileStream(this.tbAddressClient.Text.ToString(),
| FileMode.Create );
|     do {
|      iWork = rs.Read(byWork, 0, byWork.Length);
|      fs.Write(byWork, 0, iWork);
|      } while (iWork != 0);
|     fs.Flush();
|     fs.Close();
|     rs.Close();
|     resp.Close();
|     this.lblStatus.Text = "File Download - Success";
|     }
|    catch
|     {
|     this.lblStatus.Text = "File Download - Failed" ;
|     }
|    this.lblStatus.Visible = true ;
|    }
|
| Has anyone seen a simple working FtpWebRequest UploadFile example?

| This isn't quite what I needed.  This is EXACTLY what I needed.
|
| The input stream needs to be closed.
|
| What is the advantage in defining a Uri that used once vs. just using the
| string without the Uri creation?
|
| Thank you for the help.  (My original attempt had a bug that I found
after
| seeing yours solution.)

| The final "operate on a file" version that I came up with (with your
ideas
| folded in) are ...
|
|   private void DownloadFile( string strFilename, string strAddress,
string
| strUsername, string strPassword )
|    {
|    byte[] buf = new byte[2047];
|    int iWork ;
|    FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create("ftp://" +
| strAddress + strFilename );
|    req.Credentials = new NetworkCredential(strUsername, strPassword );
|    req.Method = WebRequestMethods.Ftp.DownloadFile ;
|    FtpWebResponse resp = (FtpWebResponse)req.GetResponse( );
|    Stream rs = resp.GetResponseStream( );
|    FileStream fs = new FileStream(this.tbAddressClient.Text.ToString() +
| strFilename, FileMode.Create);
|    while ( ( iWork = rs.Read( buf, 0, buf.Length ) ) > 0 )
|     fs.Write( buf, 0, iWork );
|    fs.Close();
|    rs.Close();
|    }
|
|   private void UploadFile( string strFilename, string strAddress, string
| strUsername, string strPassword )
|    {
|    byte[] buf = new byte[2048] ;
|    int iWork ;
|    FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create("ftp://" +
| strAddress + strFilename);
|    req.Credentials = new NetworkCredential(strUsername, strPassword);
|    req.Method = WebRequestMethods.Ftp.UploadFile ;
|    Stream rs = req.GetRequestStream( );
|    FileStream fs = File.Open(this.tbAddressClient.Text.ToString() +
| strFilename, FileMode.Open);
|    while ( ( iWork = fs.Read( buf, 0, buf.Length ) ) > 0 )
|     rs.Write( buf, 0, iWork );
|    rs.Close();
|    fs.Close();
|    }
|
| ... thanks for the help.
|
| My next (final) step is to come up with the "operate on a folder" version.
