  Create new folder during file Upload

  May 24, 2011 10:36 AM|LINK

  Hi,

  I am trying that when a user wants to upload a file, it has to select a directory or had to create a new one. After that it has to browse the file and click on sbmit button to upload it.

   

  But the problem that i am getting is that how i give user option to create new directory when that named directory is not present?

   

  This is my source code

   

  @{
      Layout = "~/_SiteLayout.cshtml";
      Page.Title = "Home";
  
      var fileName = "";
      var coursesRoot = Server.MapPath("~/App_Data/uploads/");
     
      if (IsPost) {
          var fileSavePath = "";
          var uploadedFile = Request.Files[0];
          fileName = Path.GetFileName(uploadedFile.FileName);
          var folder = Request["folder"];
          fileSavePath =  Path.Combine(coursesRoot, folder, fileName);
         
          // Ensure the path is rooted at CourseSubmissions.
          if (!Path.GetFullPath(fileSavePath).StartsWith(coursesRoot)) {
              Response.SetStatus(400); // Bad request. The user must have tampered with the folder names on the client
              return;
          }
         
          uploadedFile.SaveAs(fileSavePath);
      }
  }
  
  <form method="post" enctype="multipart/form-data" action="">
  <fieldset>
      <p>
          <label for="folder">Directory: </label>
          <select name="folder">
          @foreach(var folder in Directory.EnumerateDirectories(coursesRoot)){
              <option>@folder.Substring(folder.LastIndexOf("\\") + 1)</option>
          }
          </select>
      </p>
    
       <label>Upload Text File</label> @FileUpload.GetHtml(
              initialNumberOfFiles:1,
              allowMoreFilesToBeAdded:false,
              includeFormTag:false)
      <p>
      <p>
          <input type="submit" value="Upload" />
      </p>
  </fieldset>
  </form>       
  @if (IsPost) {
      <span>You have sucessfully uploaded <strong>@fileName</strong> to <strong></strong>!</span><br/>
  }

  You can use Directory.CreateDirectory to create a new folder.

  http://msdn.microsoft.com/en-us/library/system.io.directory.createdirectory(v=VS.100).aspx

  If you want to allow the user to choose a name for the directory, add an extra <input type="text" /> to your form.
