跟着Artech学习WCF(5) Responsive Service 与自定义Soap Message Header
记得以前看.NET各类框架教程在介绍SOAP时经常提到Soap Header 以前一直认为这个玩意就是个理论
应该和具体的编码和应用无关
后来在看到一些关于SOAP安全的书可以在header里 进行加密解密信息的存储 用于安全方面的验证
但一直苦于这个玩意到底是神马东西，一直没见过代码，今天Artech在介绍wcf时无意间解开期神秘的面纱，真是令人感到意外的惊喜
项目结构图如下
代码如下

Order order2 = new Order(Guid.NewGuid(), DateTime.Today.AddDays(-5), Guid.NewGuid(), "Supplier A");
string path = ConfigurationManager.AppSettings["msmqPath"];
Uri address = new Uri(path);
OrderResponseContext context = new OrderResponseContext();
context.ResponseAddress = address;
ChannelFactory<IOrderProcessor> channelFactory = new ChannelFactory<IOrderProcessor>("defaultEndpoint");
IOrderProcessor orderProcessor = channelFactory.CreateChannel();
using (OperationContextScope contextScope = new OperationContextScope(orderProcessor as IContextChannel))
{
Console.WriteLine("Submit the order of order No.: {0}", order1.OrderNo);
OrderResponseContext.Current = context;
orderProcessor.Submit(order1);
}
using (OperationContextScope contextScope = new OperationContextScope(orderProcessor as IContextChannel))

Console.WriteLine("Submit the order of order No.: {0}", order2.OrderNo);
