WCF System.Object序列化

我有一个要求，我必须使用System.Object作为WCF中的参数。 因为它不可序列化，所以我收到消息，因为它不支持操作，因为它使用System.Object。 解决这个问题的任何方法。

通过网络发送消息时，WCF默认只会序列化足以获取消息的内容，即合同成员。 如果您的消息将“对象”作为参数，则需要通过线路发送带有类型信息的额外信息。 如果在客户端和服务器上使用相同的程序集 ，则可以在服务器（和客户端）中使用NetDataContractSerializer（而不是默认的DataContractSerializer），并且它们将能够交换任意对象，如代码所示下面。 但是，正如@MarcGravell所提到的，这可能不是WCF的最佳用法……

启用NetDataContractSerializer的代码：

 public class Post_8b2c7ad7_b1c3_410b_b907_f25cee637110 { public class Person { public string Name { get; set; } public int Age { get; set; } public override string ToString() { return string.Format("Person[Name={0},Age={1}]", Name, Age); } } [ServiceContract] public interface ITest { [OperationContract] object Echo(object obj); } public class Service : ITest { public object Echo(object obj) { return obj; } } public class ReplaceSerializerOperationBehavior : DataContractSerializerOperationBehavior { public ReplaceSerializerOperationBehavior(OperationDescription operation) : base(operation) { } public override XmlObjectSerializer CreateSerializer(Type type, string name, string ns, IList knownTypes) { return new NetDataContractSerializer(name, ns); } public override XmlObjectSerializer CreateSerializer(Type type, XmlDictionaryString name, XmlDictionaryString ns, IList knownTypes) { return new NetDataContractSerializer(name, ns); } public static void ReplaceSerializer(ServiceEndpoint endpoint) { foreach (var operation in endpoint.Contract.Operations) { for (int i = 0; i < operation.Behaviors.Count; i++) { if (operation.Behaviors[i] is DataContractSerializerOperationBehavior) { operation.Behaviors[i] = new ReplaceSerializerOperationBehavior(operation); break; } } } } } public static void Test() { string baseAddress = "http://" + Environment.MachineName + ":8000/Service"; ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress)); var endpoint = host.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), ""); ReplaceSerializerOperationBehavior.ReplaceSerializer(endpoint); host.Open(); Console.WriteLine("Host opened"); ChannelFactory factory = new ChannelFactory(new BasicHttpBinding(), new EndpointAddress(baseAddress)); ReplaceSerializerOperationBehavior.ReplaceSerializer(factory.Endpoint); ITest proxy = factory.CreateChannel(); Console.WriteLine(proxy.Echo("Hello")); Console.WriteLine(proxy.Echo(123.456)); Console.WriteLine(proxy.Echo(new Uri("http://tempuri.org"))); Console.WriteLine(proxy.Echo(new Person { Name = "John Doe", Age = 33 })); ((IClientChannel)proxy).Close(); factory.Close(); Console.Write("Press ENTER to close the host"); Console.ReadLine(); host.Close(); } }
