  • Message类是WCF的基本类

  • 客户端与服务之间的所有通信最终都会产生要进行发送和接收的Message实例
  • 通常不会与Message类直接进行交互。相反，您需要使用WCF服务模型构造（如数据协定，消息协定和操作协定）来描述传入消息和传出消息。
  • 在以下情况下可能需要使用Message类
  1. 需要一种替代方式来创建传出的消息内容（例如，从磁盘上的文件直接创建消息），而不是序列化.net framework对象。
  2. 需要一种替代方式来使传入的消息内容（例如，需要将XSLT转换应用于原始XML内容），而不是反序列化为.Net Framework对象。
  3. 无论消息内容怎样都需要使用常规方式来处理消息（例如，在生成路由器，负载平衡器或发布-订阅系统时对消息进行路由或转发）。
  • 在操作中使用Messge类

  • 创建简单消息
  • Message类提供了静态的CreateMessage工厂方法
  1. 所有CreateMessage重载都采用一个类型为MessageVersion的版本参数，该参数指示要用于消息的SOAP和WS-Addressing版本，如果要使用与传入消息相同的协议版本，则可以使用OperationContext实例（从Current属性获取）上的IncomingMessageVersion属性。
  2. 大多数CreateMessage重载还具有一个字符串参数，该参数指示要用于消息的SOAP操作。
  3. 可以将版本设置为None以禁用SOAP信封生产。消息将仅包含正文。
