wp7图片上传服务器

做一个wp7手机上传图片到服务器的功能，具体丝路是在手机端做一个照相或者选择图片的功能，点击上传，在服务器端做一个一般处理程序，接受上传的文件，存入文件夹，下面是主要代码：

手机端代码：

 　　　　 /// <summary>
         /// 点击上传照片
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
         private void btn_Upload_Click(object sender, RoutedEventArgs e)
         {
             PhotoChooserTask task = new PhotoChooserTask();
             task.PixelHeight = ;
             task.PixelWidth = ;
             task.ShowCamera = true;
             task.Completed += new EventHandler<PhotoResult>(task_Completed);
             task.Show();

         }
         //选择图片完成事件，上传图片操作
         void task_Completed(object sender, PhotoResult e)
         {
             const int BLOCK_SIZE = ;

             //Code参数可以是存入服务器图片的命名
             Uri uri = new Uri("http://localhost:58556/WebClientUpLoadHandler.ashx?Code=123456", UriKind.Absolute);
             WebClient wc = new WebClient();
             wc.AllowReadStreamBuffering = true;
             wc.AllowWriteStreamBuffering = true;

             wc.OpenWriteCompleted += (s, args) =>
             {
                 using (BinaryReader br = new BinaryReader(e.ChosenPhoto))
                 {
                     using (BinaryWriter bw = new BinaryWriter(args.Result))
                     {
                         long bCount = ;
                         long fileSize = e.ChosenPhoto.Length;
                         byte[] bytes = new byte[BLOCK_SIZE];
                         do
                         {
                             bytes = br.ReadBytes(BLOCK_SIZE);
                             bCount += bytes.Length;
                             bw.Write(bytes);
                         } while (bCount < fileSize);
                     }
                 }
             };

             wc.WriteStreamClosed += (s, args) =>
             {
                 MessageBox.Show("上传成功！");
             };

             wc.OpenWriteAsync(uri, "POST");
         }

在服务器端建一个一般处理程序WebClientUpLoadHandler.ashx

代码为：

             string name = context.Request.Params["Code"].ToString();
             //获取从Silverlight客户端传来的信息
             int length = context.Request.ContentLength;
             byte[] bytes = context.Request.BinaryRead(length);
             string uploadFolder = System.AppDomain.CurrentDomain.BaseDirectory + "\\upload";

             //目录不存在则新建
             if (!Directory.Exists(uploadFolder))
             {
                 Directory.CreateDirectory(uploadFolder);
             }

             ////写入文件
             try
             {
                 using (FileStream fs = new FileStream(uploadFolder + "\\" + name+".jpg", FileMode.Create, FileAccess.Write))
                 {
                     fs.Write(bytes, , bytes.Length);
                 }
                 context.Response.Write("服务器端成功");
             }
             catch { context.Response.Write("写入失败"); }
         }

         public bool IsReusable
         {
             get
             {
                 return false;
             }
         }

成功实现了从手机端上传图片功能，在此基础上可以继续添加别的功能，在不同应用中用到。
