C# 在web目录中循环多个文件并下载

我试图从我的web目录（在IIS上）下载图像文件，所以我尝试使用web客户端通过循环下载这些文件。我有两个应用程序，一个是我部署的web应用程序，另一个是WPF应用程序，我尝试从web应用程序下载文件。这是我的密码：

     public StartWindow()
        {
            InitializeComponent();        
            string fileUploadDirectory = ConfigurationManager.AppSettings.Get("path"); 
          //  string fullpath = System.IO.Path.Combine(fileUploadDirectory, daoWordPuzzle.GetfileURL().Substring(2)); // removes  ( ~/ ) . 
 string fullpath = "http://localhost/iStellarMobile_deploy/Designs/";
                DirectoryInfo d = new DirectoryInfo(fullpath);
                FileInfo[] Files = d.GetFiles("*.png");
                foreach (FileInfo file in Files)
                {
                    string root = file.DirectoryName;
                    DownloadFile(root);
                }
        }

   protected void DownloadFile(string urlAddress)
    {
        client = new WebClient();     
        string currentpath = System.IO.Directory.GetCurrentDirectory() + @"\ImagesTest"; // Save under ImagesTest folder.
        client.DownloadFile(urlAddress, currentpath);    
    }

图像在设计文件夹中。。这就是我想下载的。。。 然后在我的App.config中：

  <appSettings>
<add key="path" value="http://localhost/iStellarMobile_deploy" />

我部署的web位于C:/inetpub/wwwroot上。那么我做错了吗？我试图通过在目录中循环下载多个文件

您试图通过http访问文件，而使用的是为文件系统设计的处理程序…抱歉，我不明白您的意思也不确定我是否可以解释，但这根本不起作用…为什么会这样？因为我试图访问http的目录？DirectoyInfo和Stuff只允许你访问应用程序文件？我想Stefan是想说http不同于ftp。

protected void DownloadData(string strFileUrlToDownload)
    {
        WebClient client = new WebClient();
        byte[] myDataBuffer = client.DownloadData(strFileUrlToDownload);         

        MemoryStream storeStream = new MemoryStream();

        storeStream.SetLength(myDataBuffer.Length);
        storeStream.Write(myDataBuffer, 0 , (int)storeStream.Length);

        storeStream.Flush();

        string currentpath = System.IO.Directory.GetCurrentDirectory() + @"\Folder"; //folder to contain files.

        using (FileStream file = new FileStream(currentpath, FileMode.Create, System.IO.FileAccess.ReadWrite))
        {
            byte[] bytes = new byte[storeStream.Length];
            storeStream.Read(bytes, 0, (int)storeStream.Length);
            file.Write(myDataBuffer, 0, (int)storeStream.Length);
            storeStream.Close();
        }

        //The below Getstring method to get data in raw format and manipulate it as per requirement
        string download = Encoding.ASCII.GetString(myDataBuffer);


    }
