wcf unknownmessage与iis主机接收

Question

如果我有一个WCF应用程序托管在IIS上，我该如何处理 UnknownMessageReceived事件？

我知道如何在构建控制台主机时执行此操作。

您可以使用服务主机工厂来访问在IIS下使用的服务主机实例。您可以在http://blogs.msdn.com/b/carlosfigueira/archive/2011/06/14/wcf-extensibility-servicehostfactory.aspx找到更多关于服务主机工厂的信息，下面的代码显示了一个工厂，它监听UnknownMessageReceived事件。

public class MyFactory : ServiceHostFactory 
{ 
    protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) 
    { 
     ServiceHost host = base.CreateServiceHost(serviceType, baseAddresses); 
     host.UnknownMessageReceived += new EventHandler<UnknownMessageReceivedEventArgs>(host_UnknownMessageReceived); 
     return host; 
    } 

    void host_UnknownMessageReceived(object sender, UnknownMessageReceivedEventArgs e) 
    { 
     // do something with the message 
    } 
}
