What do you mean by deleting from the front end application?

shakil4u 23-Aug-12 8:46am

means i am storing the files in separate folder with the name UploadedFiles i need to delete from it

Just use the File object. http://msdn.microsoft.com/en-us/library/system.io.file.delete.aspx

You have confused with frontend and server. What I have understood, you are uploading file from client end to server and once the file is uploaded you need to delete the local files. Is it what you intend to do?

yes

Solution 1

jquery can make an AJAX call and tell the server to delete a file. But, it cannot do file operations ( actually, it can't do anything javascript can't do, as that's all it is ), nor can it see the server, except to make HTTP requests.

So, as you have cleared, you want to delete file(s) located in client side after you upload the file(s) to the server.

As it is clear from your statement that this application will be run from a controlled environment. So, you need some security access permission to delete the files from the folder.

In Javascrip, try this..

<script type="text/javascript">
    // initialize ActiveXObject and create an object of Scripting.FileSystemObject.
    var fso = new ActiveXObject('Scripting.FileSystemObject');
    fso.DeleteFile("C:\\Temp\\customefolder\\file.txt, true);

    fso = null;
</script>

hope this helps.
cheers

C#

public ActionResult Delete(string FileName)
      {

        char DirSeparator = System.IO.Path.DirectorySeparatorChar;

        string FilesPath = ";" + FileName;
        string filenameonly = name + Path.GetFileName(FilesPath);
        string FPath = "Content" + DirSeparator + "UploadedFiles" + DirSeparator + filenameonly;
        // Don't do anything if there is no name
        if (FileName.Length == 0) return View();
        // Set our full path for deleting
        string path = FilesPath + DirSeparator;
        // Check if our file exists
        if (System.IO.File.Exists(Path.GetFullPath(AppDomain.CurrentDomain.BaseDirectory + FPath)))
        {
            // Delete our file
            System.IO.File.Delete(Path.GetFullPath(AppDomain.CurrentDomain.BaseDirectory + FPath));

        }
         model = bug;
        Session["CaptureData"] = model;

       
        return View("LoadBug", Bug);
    }
    public string name { get; set; }
    public object Bug { get; set; }
}
