C# 从运行在IIS 7上的另一个Net.Tcp WCF服务调用自托管WCF服务

我的客户机上运行着一个NetTcp自托管服务，服务器上的IIS上运行着另一个NetTcp服务。我正在尝试使用IIS中的自托管服务。它正在引发带有超时错误的异常

我使用WCF测试客户端来测试自托管服务，它运行良好。此外，我还编写了一个示例C#应用程序，该应用程序调用自托管服务，并且运行良好。只有当IIS上的服务尝试调用时，这才是失败的

我猜IIS上一定有某种安全设置，它会阻止传出呼叫，从而导致超时。有线索吗

调用自托管服务的代码：

private object CallClient(string message)
    {
        var myBinding = new NetTcpBinding(SecurityMode.None);
        var myEndpoint = new EndpointAddress("net.tcp://<myIP>:8188/MessageReceiverService/");
        var myChannelFactory = new ChannelFactory<IMessageReceiverService>(myBinding, myEndpoint);

        IMessageReceiverService client = null;
        var result = new MessageCenterResponse { Result = message };

        try
        {
            client = myChannelFactory.CreateChannel();
            result.Result += client.TestMethod("Shankar");
        }
        catch (Exception ex)
        {
            if (client != null)
            {
                ((ICommunicationObject)client).Abort();
            }
            result.Result += "Exception!!" + myEndpoint.Uri + " - " + ex.Message;
        }
        finally
        {
            ((ICommunicationObject)client).Close();
        }

        return result;
    }

public bool TestMethod(string testMessage)
    {
        return testMessage.Equals("Shankar");
    }

private void StartMessageCenterService()
    {
        var tcpUrl = new Uri("net.tcp://<myIP>:8188/MessageReceiverService/");
        var messageCenterHost = new ServiceHost(typeof(MessageReceiverService), tcpUrl);

        messageCenterHost.Faulted += MessageCenterHost_Faulted;

        messageCenterHost.Open();
    }

<services>
  <service name="MessageCenter.Proxy.VirtualServer.MessageReceiverService" behaviorConfiguration="DebugServiceBehavior">
    <endpoint address=""
              binding="netTcpBinding"
              bindingConfiguration="InsecureTcp"
              behaviorConfiguration="LargeDataEndpointBehavior"
              contract="MessageCenter.Common.Interfaces.IMessageReceiverService">
    </endpoint>
    <endpoint address="mex"
              binding="mexTcpBinding"
              contract="IMetadataExchange" />
  </service>
</services>

上述代码在从独立应用程序调用时工作正常，但在以下行之后从IIS调用时失败：

client.TestMethod（“Shankar”）

这是我启动自托管服务的方式：

private object CallClient(string message)
    {
        var myBinding = new NetTcpBinding(SecurityMode.None);
        var myEndpoint = new EndpointAddress("net.tcp://<myIP>:8188/MessageReceiverService/");
        var myChannelFactory = new ChannelFactory<IMessageReceiverService>(myBinding, myEndpoint);

        IMessageReceiverService client = null;
        var result = new MessageCenterResponse { Result = message };

        try
        {
            client = myChannelFactory.CreateChannel();
            result.Result += client.TestMethod("Shankar");
        }
        catch (Exception ex)
        {
            if (client != null)
            {
                ((ICommunicationObject)client).Abort();
            }
            result.Result += "Exception!!" + myEndpoint.Uri + " - " + ex.Message;
        }
        finally
        {
            ((ICommunicationObject)client).Close();
        }

        return result;
    }

public bool TestMethod(string testMessage)
    {
        return testMessage.Equals("Shankar");
    }

private void StartMessageCenterService()
    {
        var tcpUrl = new Uri("net.tcp://<myIP>:8188/MessageReceiverService/");
        var messageCenterHost = new ServiceHost(typeof(MessageReceiverService), tcpUrl);

        messageCenterHost.Faulted += MessageCenterHost_Faulted;

        messageCenterHost.Open();
    }

<services>

var messageCenterHost=新服务主机（typeof（MessageReceiverService），tcpUrl）；
messageCenterHost.Faulted+=messageCenterHost\u Faulted；
messageCenterHost.Open（）；
}

            client = myChannelFactory.CreateChannel();
            result.Result += client.TestMethod("Shankar");
        }

            }
            result.Result += "Exception!!" + myEndpoint.Uri + " - " + ex.Message;
        }
        finally

您能从IIS盒使用WCF测试客户端连接到您的自托管服务吗？并不是说它能修复安全错误，而是对于相同的盒名，管道是一种更有效的传输方式。@Blam，我正在本地机器上测试，但最终服务将在服务器盒上运行，和不同机器上的客户机代码。@500-内部服务器错误，我目前正在本地机器上运行这两个程序来测试。自托管服务正在端口8188上运行。请检查IIS设置和防火墙。
