在网络中传输XAML元素 [英] Transfer XAML Elements in Network

问题描述

我想通过网络传输XAML元素(如椭圆或矩形).

我可以序列化它们，但是在转移和强制转换后，结果对象的属性为空.

为什么会这样呢?


服务器

I want to transfer my XAML-Elements (like Ellipses or Rectangles) over the Network.

I am able to Serialize them but after the transfer and the casting the attributes of my resulting object are empty.

Why this happens ?


Server

MemoryStream ms = new MemoryStream();
XamlWriter.Save(element, ms);
byte[] ele = ms.ToArray();
ms.Close();

客户端

Client

MemoryStream ellipse = new MemoryStream(ellipseBytes);
Ellipse myEli = (Ellipse)XamlServices.Load(ellipse);

推荐答案

原因不匹配:

要么同时使用XamLWriter和XamlReader，要么使用XamlSevices.Load和.Parse方法

请谨慎使用此处的外部参考.但是，只要使用简单的对象，它就会起作用.


在codeproject中检查此处[ ^ ]
http://msdn.microsoft.com/en -us/library/system.windows.markup.xamlreader(v = vs.100).aspx [ http://msdn.microsoft.com/zh-cn/library/system.xaml.xamlservices.parse％28v = VS.100％29.aspx [

The reason is a mismatch :

either use both XamLWriter and XamlReader or use XamlSevices.Load and .Parse methods

careful with external references here. But as long as you use simple objects, it will work.


Check here in codeproject[^]
