稳扎稳打Silverlight(39) - 3.0通信之二进制XML通信, 本地连接

作者： webabcd


介绍
Silverlight 3.0 通信的新增功能

• 二进制XML通信 - 与 WCF 服务间通信，可以使用二进制 XML 传递数据（提高传输性能） 
• 本地连接 - 允许客户端的两个 Silverlight 程序之间直接进行通信（不用通过服务端）

示例
1、以二进制 XML 传递数据的演示
服务端（WCF）

        [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
         public  class BinaryXmlService 
        { 
                [OperationContract] 
                 public  string Hello( string name) 
                { 
                         return  "Hello: " + name; 
                } 
        } 
}
