【问题描述】：

我的配置中有以下内容：

<behaviors>
<endpointBehaviors>
        <behavior name="protoEndpointBehavior">
          <protobuf />
        </behavior>
      </endpointBehaviors>
    </behaviors>

如何以编程方式添加 protobuf 行为，而不是将其放在配置文件中？

到目前为止我有这个代码：

ServiceHost serviceHost = null;
                Console.WriteLine("Creating service " + serviceType.FullName);
                serviceHost = new MyServiceHost(serviceType, uriList.Select(c => new Uri(c)).ToArray());

                serviceHost = new MyServiceHost(serviceType, uriList.Select(c => new Uri(c)).ToArray());

                if (secureConnectionSettings != null && secureConnectionSettings.Enabled)
                {
                    Console.WriteLine("Setting certificates");
                    X509Store store = new X509Store(secureConnectionSettings.CertificateStore, secureConnectionSettings.CertificateLocation);
                    store.Open(OpenFlags.ReadOnly);
                    X509Certificate2Collection certs = store.Certificates.Find(X509FindType.FindByThumbprint, secureConnectionSettings.Thumbprint, true);
                    store.Close();

                    if (certs.Count > 0)
                        serviceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindByThumbprint, secureConnectionSettings.Thumbprint);
                    else
                        throw new Exception("Could not finde certificate with thumbprint " + secureConnectionSettings.Thumbprint);
                }

                var binding = CreateNetHttpBinding();

                var endpoint = new System.ServiceModel.Description.ServiceEndpoint(new System.ServiceModel.Description.ContractDescription("My.ServiceContracts.IMyClientService"), binding, new EndpointAddress("BinaryHttpProto"));
                endpoint.EndpointBehaviors.Add( new ProtoBuf.ServiceModel.ProtoBehaviorExtension());
                serviceHost.AddServiceEndpoint(endpoint);

以下行不起作用：

endpoint.EndpointBehaviors.Add( new ProtoBuf.ServiceModel.ProtoBehaviorExtension());

【问题讨论】：

不起作用是什么意思？它会抛出异常吗？

标签： c# wcf service

【解决方案1】：

我对那个库了解不多，但您正在尝试添加配置扩展元素，而不是实际行为。

如果你这样做，它会起作用吗？

endpoint.EndpointBehaviors.Add( new ProtoBuf.ServiceModel.ProtoEndpointBehavior());

非常感谢 tomasr！
