wcf - WCF 中的另一个应用程序正在使用的端口

Question

我在尝试使用以下配置运行时遇到了 WCF 自托管应用程序的问题:

  <system.serviceModel>
    <services>
      <service name="statisticsCollectingService">
        <endpoint address="net.tcp://localhost:8200/RadioStatistics/"
                binding="netTcpBinding"
                contract="RadioStatistics.Services.IStatisticsCollectingService" />
        <endpoint address="http://localhost:8100/RadioStatistics/"
                binding="basicHttpBinding"
                contract="RadioStatistics.Services.IStatisticsCollectingService" />
      </service>

      <service name="biDataExportService">
        <endpoint address="net.tcp://localhost:8001/RadioStatistics/" 
                  binding="netTcpBinding" 
                  contract="RadioStatistics.Services.IBIDataExportService" />
      </service>
    </services>
  </system.serviceModel>

异常发生如下:

System.Configuration.ConfigurationErrorsException: Error creating context 'spring.root': The process cannot access the file because it is being used by another process ---> Spring.Objects.Factory.ObjectCreationException: Error creating object with name 'statisticsCollectingServiceHost' defined in 'config [C:\TTL\zer_rel_12_1_main_TTL_C1077\TTL\CommonTools\RadioStatistics\bin\Debug\RadioStatistics.ServerApp.vshost.exe.Config#spring/objects] line 4' : Initialization of object failed : HTTP could not register URL http://+:8000/RadioStatistics/services/ because TCP port 8000 is being used by another application. ---> System.ServiceModel.AddressAlreadyInUseException: HTTP could not register URL http://+:8000/RadioStatistics/services/ because TCP port 8000 is being used by another application. ---> System.Net.HttpListenerException: The process cannot access the file because it is being used by another process

运行 Windows XP SP3 已经尝试执行以下操作:

httpcfg set urlacl /u http://+:8100/RadioStatistics/ /a "D:(A;;GX;;;BU)"

(我猜一般授权和/或用户的所有可能的变体 - 比如 DU(对于域用户？)

还试图添加到 IP 列表

httpcfg set iplisten -i 0.0.0.0:8100

这是在我在事件日志中找到一个事件之后:

Unable to bind to the underlying transport for 0.0.0.0:8100. The IP Listen-Only list may contain a reference to an interface which may not exist on this machine. The data field contains the error number.

最糟糕的是，它过去已经开始工作了(几周前我去度假之前)。机器对我来说似乎没有改变，因为它没有被触摸。但是这个错误让我发疯。最糟糕的是，无论选择哪个端口都会发生错误。

当然，在basicHttpBinding 被移除后它可以正常工作。

您可能在同一端口上监听其他内容。尝试运行

netstat -o -n -a 

获取所有进程的列表以及它们正在监听的内容。
