WPF上传文件到服务器

利用WebClient 上传文件到服务器

创建一个空网站，创建一个UploadFile.aspx项，

服务器报500错误：检查文件保存路径是否存在，检查文件大小限制

     protected void Page_Load(object sender, EventArgs e)
        {
            foreach (string f in Request.Files.AllKeys)
            {    //在客户端传入新的文件
                HttpPostedFile file = Request.Files[f];
                //在客户端传入一个新的文件名
                string directory = Request.QueryString["d"];
                string filename = Request.QueryString["n"];
                //file.SaveAs(Server.MapPath("../ReportFile/" + filename + file.FileName.Substring(file.FileName.IndexOf("."))));
                string path = string.Format(@"G:\ReportFile\{0}\", directory);
                if (!Directory.Exists(path)) { Directory.CreateDirectory(path); }
                file.SaveAs(path + filename);
            }
        }

WPF中

 using form = System.Windows.Forms;
         private const string directory = "";
         public void Upload(string file)
         {
             FileInfo info = new FileInfo(file);
             string url = string.Format("http://192.168.31.118:54040/UploadFile.aspx?d={0}&n={1}", directory, info.Name);
             WebClient client = new WebClient();
             client.Credentials = CredentialCache.DefaultCredentials;
             client.UploadFileAsync(new Uri(url), file);
             client.UploadFileCompleted += new UploadFileCompletedEventHandler(result_UploadFileCompleted);
         }
         private void result_UploadFileCompleted(object sender, UploadFileCompletedEventArgs e)
         {
             if (e.Error != null)
             {
                 MessageBox.Show("上传失败：" + e.Error.Message);
             }
             else
             {
                 MessageBox.Show("上传成功！");
             }
         }

         private void UploadFile_Click(object sender, RoutedEventArgs e)
         {
             form.OpenFileDialog _dialog = new form.OpenFileDialog();
             _dialog.Multiselect = true;
             if (_dialog.ShowDialog() == form.DialogResult.OK)
             {
                 string[] _files = _dialog.FileNames;
                 if (_files != null && _files.Length > )
                 {
                     foreach (var item in _files)
                     {
                         Upload(item);
                     }
                 }
             }
         }
