Delete remote files?

I have files that I want to delete. Connection can be from file sharing, http, and ftp.

Example of files to delete:

//mytest//delete//filename.bin
ftp://mytest/delete/filename.bin
http://mytest/delete/filename.bin

Here's what I did:

Uri target = new Uri(@"ftp://mytest/delete/filename.bin");
FileInfo fi = new FileInfo(target.AbsoluteUri);
fi.Delete();

The error I get is:

The given paths format is not supported

Is there a single code that can delete in all these file types?

I have created a simple code for this task(based on thread response).

This is the input:

Uri target = new Uri(@"ftp://tabletijam/FileServer/upload.bin");
Uri target = new Uri(@"http://tabletijam/FileServer/upload.bin");
Uri target = new Uri(@"\\tabletijam\FileServer\upload.bin");

This is the code:

bool DeleteFileOnServer(Uri serverUri)
{
    if (serverUri.Scheme == Uri.UriSchemeFtp)
    {
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
        request.Method = WebRequestMethods.Ftp.DeleteFile;

        FtpWebResponse response = (FtpWebResponse)request.GetResponse();
        lblStatus.Content = response.StatusDescription;

        response.Close(); 

        return true;
    }
    else if (serverUri.Scheme == Uri.UriSchemeFile)
    {
        System.IO.File.Delete(serverUri.LocalPath);

        return true;
    }
    else if (serverUri.Scheme == Uri.UriSchemeHttp || serverUri.Scheme == Uri.UriSchemeHttps)
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serverUri);
        request.Method = WebRequestMethods.Http.DeleteFile;

        Htt开发者_StackOverflowpWebResponse response = (HttpWebResponse)request.GetResponse();
        lblStatus.Content = response.StatusDescription;

        response.Close();

        return true;
    }
    else
    {
        lblStatus.Content = "Unknown uri scheme.";
        return false;
    }
}

Ftp and File deleted successfully. WebRequestMethods.Http does not contain DeleteFile.

So my question is, how do I delete file from this URI?

http://tabletijam/FileServer/upload.bin

Because FileInfo only works with local files. For each connection you will need a special implementation.

For FTP: (example from MSDN)

public static bool DeleteFileOnServer(Uri serverUri)
{
    // The serverUri parameter should use the ftp:// scheme.
    // It contains the name of the server file that is to be deleted.
    // Example: ftp://contoso.com/someFile.txt.
    // 

    if (serverUri.Scheme != Uri.UriSchemeFtp)
    {
        return false;
    }
    // Get the object used to communicate with the server.
    FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUri);
    request.Method = WebRequestMethods.Ftp.DeleteFile;

    FtpWebResponse response = (FtpWebResponse) request.GetResponse();
    Console.WriteLine("Delete status: {0}",response.StatusDescription);  
    response.Close();
    return true;
}

Using the \\server... notation, you can delete file (that you have access) to on remote servers.

Using FTP, you should the FtpWebRequest.

For HTTP, you could issue a DELETE request, using HttpWebRequest.

For both FTP and HTTP, you might need to supply a username and password. Also normally HTTP servers are not configured to delete files when receiving a DELETE request by default.

For a whole lot of reasons, no, there is not a single unified way you can delete files via each of these protocols.

You could abstract this away into some implementation of your own, however, using an implementation specific to each of the protocols you want to support...

how do i delete file from this uri?

request.Method = "DELETE";

Also, there's a different header supported by WebDAV for controlling the delete...

No, this is not possible. FTP and HTTP are protocols that you are required to stick to. Even though you may be able to delete files when viewing FTP folders in the Explorer doesn't mean it works from C#, too, because the Explorer uses an integrated FTP client. Deleting files via HTTP like that isn't possible at all.
