.NET 服务参考 - Soap 客户端状态始终为故障

Question

我有一个 .NET Web 表单应用程序，它使用 soap Web 服务进行某些操作。在我的解决方案中，项目很少，其中一个负责肥皂操作。因此，我向该项目添加了服务参考。我的旧发布运行良好，但现在，我无法调用 Web 服务中的任何方法，因为会抛出错误。

错误信息：

The communication object, System.ServiceModel.ChannelFactory`1[ProjectName.IntegrationServiceSoap], cannot be used for communication because it is in the Faulted state.

每当我创建 soap 客户端实例时，它的 state 属性总是 Faulted。

我用测试端点对其进行了测试，删除并重新添加了服务引用，但它不起作用。

堆栈跟踪：

   at System.ServiceModel.Channels.CommunicationObject.ThrowIfDisposed()
   at System.ServiceModel.ChannelFactory.EnsureOpened()
   at System.ServiceModel.ChannelFactory`1.CreateChannel(EndpointAddress address, Uri via)
   at System.ServiceModel.ChannelFactory`1.CreateChannel()
   at System.ServiceModel.ClientBase`1.CreateChannel()
   at System.ServiceModel.ClientBase`1.CreateChannelInternal()
   at System.ServiceModel.ClientBase`1.get_Channel()
   at SoapLibrary.IntegrationServiceSoapClient.ProjectName.IntegrationServiceSoap.GetTicket(TicketRequest request) in C:\Users\...

这是我的配置文件

主要项目Web.config

            </basicHttpBinding>
        </bindings>

                contract="MyService.IntegrationServiceSoap" name="IntegrationServiceSoap" />
        </client>
    </system.serviceModel>
</configuration>

有什么想法吗？我该如何解决这个问题？

Answer 1

我通过将项目的 .NET Framework 版本从 4.5.1 降级到 4.5

解决了这个问题

我还在我的 SoapClient 中添加了故障侦听器。

    private void CreateSoapClient()
    {
        client = new IntegrationServiceSoapClient("IntegrationServiceSoap");
        client.ChannelFactory.Faulted += ChannelFactory_Faulted;
    }

    private void ChannelFactory_Faulted(object sender, EventArgs e)
    {
        client.Abort();
        client.ChannelFactory.Faulted -= ChannelFactory_Faulted;
        client = null;
        CreateSoapClient();
    }

我不知道到底是什么问题。现在，我的客户工作没有任何问题。
