Simple FTP Upload in C# w Free FTP DLL

  • 發行項

Two nights ago I created an app that lets me just right-click a file in Windows Explorer and it uploads the file to my FTP site in a temp directory so I can quickly and easily share files with friends.  Just click it’s uploaded, and click the resulting URL is copied into the clipboard to be pasted into an e-mail, Word, blog post, etc.

To do this, I needed to upload a file to an FTP site.  There is a FtpWebRequest class in System.Net, but it was cryptic to use for just a simple file upload.  Our MSDN documents could definitely use more sample code!  Hopefully the new MSDN Wiki will help.  But after much searching, I came across BytesRoad.NetSuit, a free .NET library that was real easy to use!  It does more than just FTP, but here’s my code showing how easy it is to upload a file.

using System.IO;

using BytesRoad.Net.Ftp;

namespace CoadTools.Ftp

{

  public class FtpToools

  {

    public static void UploadFile(int Timeout, string FtpServer,

      string Username, string Password, string RemotePath,

      string LocalFile)

    {

      // get instance of the FtpClient

      FtpClient client = new FtpClient();

      // use passive mode

      client.PassiveMode = true;

      // connect to the specified FTP server

      client.Connect(Timeout, FtpServer, 21);

      client.Login(Timeout, Username, Password);

      // build the target file path

      string target = Path.Combine(RemotePath,

        Path.GetFileName(LocalFile)).Replace("\\", "/");

      // synchronously upload the file

      client.PutFile(Timeout, target, LocalFile);

    }

  }

}

    Hey crew, yup, the link was broken as the target site was down and it looks tough to get elsewhere, so I've put the FTP library on my FTP.  Cheers! http://coad.net/blog/resources/BytesRoad.NetSuit_2_0.zip

    Hey Noah, I think this library is amazing, but there's not much documentation about it..... Do you have more code samples using this library? Thanks a lot

    I completely agree that it's way too much work just to upload a file in .net. Thanks for the code, it worked great!

    Hi, I am trying to use the above sample. However, while the connection to the server is successful, I get the below error when the PutFile command is executed: "An existing connection was forcibly closed by the remote host" Any help in this will be appreciated. Thanks.

    Is It possible to upload a file from one server to another server (Not a local server).

    4 Sachin This is bits of my code that I have taken out. This checks the file name if it ends with .txt and only executes the getfile command if the file has an .txt extension.

Dim idx as integer = 0 Dim item As FtpItem = items(idx)           If item.Name.ToString.EndsWith(".txt") Then       Try                        'fetching the file                        ftp.GetFile(timeout, dstpath, srcFilePath)       Catch ex As Exception       End Try End If

Havent tested but would suggest you try If item.Name.ToString.StartsWith("Sam") Then ftp.GetFile(timeout, dstpath, srcFilePath) End If

    Shaf & Danish, use the bold link in the blog post above titled "BytesRoad.NetSuit" to download the source code and DLL.  Or do an internet search for the that term to find many other places to download it.

    If some are getting an operation failed message while upload, check that it might be a firewall (such as the one with an internet security package or windows) that blocks it. i solved this problem by switching my firewall to trusted connection or off in case while uploading and it worked for me.
