Figure B Upload filesĪs you can see it takes over two times as many lines of code to upload than it does to download a file.
Anytime you open a file in this manner you need to close it or the file will not be accessible by other processes. Figure A Download filesīe aware that the final file.Close() call is crucial.
The complete code for this is shown in Figure A. This byte array is then written to a file, and the download is complete. The DownloadData method returns an array of bytes which represent the downloaded file. The next step is to call the DownloadData method of the WebClient object and supply the URI of the file we want to download. What we need to do is setup a WebClient object and set the Credentials property to our login information. Download filesĭownloading files is significantly easier than uploading them, so we’ll start out with downloading. These may be simple and you may think “man, who wouldn’t understand that?” Well, when I first started moving files to/from FTP servers I didn’t understand some of these concepts so I thought they would be important! Now let’s get to the code. You’ll use this object both when uploading and downloading files.
The URI provided to the request object will include the file name you want to upload or download.

This tells the request how to authenticate against the FTP server. Each request will need a NetworkCredentials object attached to its Credentials property.Preliminary thoughtsīefore we get into moving files around I would like to bring a few things to light: This blog post is also available in PDF form as a TechRepublic download, which includes a sample Visual Studio file with sample code explaining the techniques outlined. This document concentrates on showing you the easy way to take advantage of what Microsoft has provided in the. Recognizing this, Microsoft has given developers a fairly straight forward method to implement this functionality. Even automated processes regularly interact with FTP servers to transfer data. Many applications require the ability to upload and download files via FTP. How do I… Use C# to upload and download files from an FTP server?
