c# - How to use custom serialization WCF?

Question

Has any one ever implemented a custom serializer in WCF ? The reason i want to replace the WCF default serializer with custom serializer is to call different services from the same wcf proxy client.I would be glad if some one can suggest a way to do this ?

Answer 1

I did something similar on a project I recently did.

However I did have 2 different WCF clients. How I "switched" was I then created a shared interface between the clients and then used a ServiceLocator to fetch the IClient.

Does this make sense?

Answer 2

如果我正确理解了这个问题，那么您有一个应用程序，您想与基于某些标准使用相同接口的两个服务之一进行通信。这些服务具有不同的配置，因此您不能重复使用相同的配置。

为了解决这个问题，我将在应用程序配置中设置两个配置，如果您愿意，也可以在代码中完成。

<client>
  <endpoint address="http://service1"
            binding="basicHttpBinding"
            bindingConfiguration="Service1Binding"
            behaviorConfiguration="Service1Behavior"
            contract="IServiceInterface, Service"
            name="Service1"/>

  <endpoint address="http://service2"
            binding="basicHttpBinding"
            bindingConfiguration="Service2Binding"
            behaviorConfiguration="Service2Behavior"
            contract="IServiceInterface, Service"
            name="Service2"/>
</client>

然后，在您的代码中，您需要某种条件语句来确定您要与哪个服务通信。完成此操作后，您可以ChannelFactory为所需的配置创建一个。

string serviceName = FullMoon ? "Service1" : "Service2";

var channelFactory = new ChannelFactory<IServiceInterface>(serviceName);

var proxy = channelFactory.CreateChannel();

proxy.SomeServiceCall();

channelFactory.Close();

如果您使用 IoC 注入代理，您可能需要将其推送到某种工厂。您还可以考虑优化这一点，因为创建 ChannelFactory 是昂贵的部分，可以创建 Factory 而无需仅指定合同的配置。然后，您需要在创建通道时指定绑定和端点。
