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 = "0123";
        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 > 0)
                {
                    foreach (var item in _files)
                    {
                        Upload(item);
                    }
                }
            }
        }
