silverlight中HttpResponse解决思路

silverlight中HttpResponse
我要写一个单击按钮，提示一个提示框，上面有保存和打开，代码如下

 HttpResponse Response = HttpContext.Current.Response;

  Response.ContentType = "application/soap+msbin1";
  //通知浏览器下载文件
  Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode("Excel文件", System.Text.Encoding.UTF8));
  Response.BinaryWrite(bytes);
  Response.Flush();
  Response.End();


为什么不对啊，老是提示错误，求指点

[解决办法]
Silverlight是客户端的，不是服务器端的，没有Response.AddHeader

Response.AddHeader需要写到服务器端的asp.net中

不明白你要干什么
你可以使用SaveFileDialog
