c# - svcutil 无法为自托管 wcf 服务生成接口
问题描述
你能帮我解决我的错误吗？
我在 WinForm 程序集中自托管 WCF，我正在尝试生成客户端 app.config 和服务接口。我在 VS2015 开发人员命令提示符下执行 svcutil http://localhost:8880/MyOwnWCFService/ /Language=c# /t:Code /out:C:\Service\ServiceProxy.cs /config:C:\Service\ServiceProxy.config .
我收到以下错误：
错误：无法从http://localhost:8880/MyOwnWCFService/获取元数据
如果这是您有权访问的 Windows (R) Communication Foundation 服务，请检查您是否已在指定地址启用元数据发布。有关启用元数据发布的帮助，请参阅位于http://go.microsoft.com/fwlink/?LinkId=65455的 MSDN 文档。
WS 元数据交换错误 URI：http://localhost:8880/MyOwnWCFService/
Metadata contains a reference that cannot be resolved: 'http://localhost:8880/MyOwnWCFService/'.
Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost:8880/MyOwnWCFService/. The client and service bindings may be mismatched.
The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..
HTTP GET 错误 URI：http://localhost:8880/MyOwnWCFService/
There was an error downloading 'http://localhost:8880/MyOwnWCFService/'.
请求失败并显示错误消息：

由于内部错误，服务器无法处理请求。有关该错误的更多信息，请在服务器上打开 IncludeExceptionDetailInFaults（来自 ServiceBehaviorAttribute 或来自配置行为）以便将异常信息发送回客户端，或者根据 Microsoft .NET Framework SDK 文档打开跟踪并检查服务器跟踪日志。 --.
如果您需要更多帮助，请输入“svcutil /?”
我的自托管代码：
System.ServiceModel.Channels.Binding MexHttpBinding = MetadataExchangeBindings.CreateMexHttpBinding();
String baseAddress = "http://localhost:8880/MyOwnWCFService/";
NetTcpBinding tcpbinding = new NetTcpBinding(SecurityMode.None);
tcpbinding.Name = "SEMSIntegration_NetTcpBinding_iSEMSIntegrationWCFService";
tcpbinding.OpenTimeout = new TimeSpan(00, 01, 00);
tcpbinding.CloseTimeout = new TimeSpan(00, 01, 00);
tcpbinding.ReceiveTimeout = new TimeSpan(00, 01, 00);
tcpbinding.SendTimeout = new TimeSpan(00, 01, 00);
tcpbinding.TransactionFlow = false;
tcpbinding.TransferMode = TransferMode.Buffered;
tcpbinding.TransactionProtocol = TransactionProtocol.OleTransactions;
tcpbinding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
tcpbinding.ListenBacklog = 10;
tcpbinding.MaxBufferPoolSize = 524288;
tcpbinding.MaxBufferSize = 524288;
tcpbinding.MaxConnections = 100;
tcpbinding.MaxReceivedMessageSize = 524288;
WindowState = FormWindowState.Minimized;
SEMSService = new MyOwnWCFService();
SEMSHost = new ServiceHost(SEMSService, new Uri(baseAddress));
ServiceMetadataBehavior smb = SEMSHost.Description.Behaviors.Find<ServiceMetadataBehavior>();
// If not, add one
if (smb == null)
{
smb = new ServiceMetadataBehavior();
}
smb.HttpGetEnabled = true;
smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
SEMSHost.Description.Behaviors.Add(smb);
SEMSHost.Description.Behaviors.Add(new ServiceDiscoveryBehavior());
SEMSHost.AddServiceEndpoint(new UdpDiscoveryEndpoint());
SEMSHost.AddServiceEndpoint(typeof(iSEMSIntegrationWCFService), new BasicHttpBinding(), "http://localhost:8880/MyOwnWCFService");
SEMSHost.AddServiceEndpoint(typeof(iSEMSIntegrationWCFService), tcpbinding, "net.tcp://localhost:8888/MyOwnWCFService");
SEMSHost.AddServiceEndpoint("IMetadataExchange", MexHttpBinding, "mex");
SEMSHost.Open();
解决方案
This is because you are getting the error:
System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Forms.Menu' cannot be serialized.
See browser exception detail:
An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior
contract: http://tempuri.org/:iSEMSIntegrationWCFService ----> System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Forms.Menu' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types.
