错误配置的WCF服务器主机名也不例外

我有一个使用WCF的服务器客户端实现,客户端在启动时向服务器发送Connect消息。

这是我在客户端应用程序中使用的代码(在这种情况下,WCF服务是自托管的):

public void InitializeCommunicationChannel()
    {
        this._proxy = new DistributionServiceClient(this._context, "NetTcpBinding_IDistributionService");

        Log.Write(Level.Debug, "Initialized proxy..");

        //set credentials
        this._proxy.ClientCredentials.Windows.ClientCredential.Domain = PasswordManager.ServerAdminDomain;
        this._proxy.ClientCredentials.Windows.ClientCredential.UserName = PasswordManager.ServerAdminUsername;
        this._proxy.ClientCredentials.Windows.ClientCredential.Password = PasswordManager.ServerAdminPassword;

        this._proxy.InnerChannel.Faulted += new EventHandler(this.InnerChannel_Faulted);
        this._proxy.InnerChannel.Closing += new EventHandler(this.InnerChannel_Closing);

        //send a connect message to the server
        try
        {
            Log.Write(Level.Debug, "Sending connect message..");

            this.StationId = this._proxy.ClientConnected(ClientConfiguration.HostName, this.Version, ClientConfiguration.CurrentIpAddress);
            Log.Write(Level.Debug, "Connect message sent..");

            Log.Write(Level.Info, "Connected to server.");
            this.ConnectionState = "Connected";
        }
        catch (ConfigurationErrorsException cEx)
        {
            Log.Write(Level.Error, cEx.Message);
            Log.Write(Level.Debug, cEx.ToString());
        }
        catch (FaultException fEx)
        {
            //probably server didn't recognize configured ip or hostname
            Log.Write(Level.Error, fEx.Message);
            Log.Write(Level.Debug, fEx.ToString());
        }
        catch (CommunicationException cEx)
        {
            Log.Write(Level.Debug, cEx.Message);
            Log.Write(Level.Debug, cEx.ToString());
        }
        catch (System.Security.Authentication.InvalidCredentialException iEx)
        {
            Log.Write(Level.Error, iEx.Message);
            Log.Write(Level.Debug, iEx.ToString());
        }
        catch (Exception ex)
        {
            Log.Write(Level.Error, ex.Message);
            Log.Write(Level.Debug, ex.ToString());
        }

    void InnerChannel_Closing(object sender, EventArgs e)
    {
        Log.Write(Level.Debug, "Communication channel is closing down..");
        this.ConnectionState = "Attempting connection..";
    }

    void InnerChannel_Faulted(object sender, EventArgs e)
    {
        this.ConnectionState = "Not connected";
        Log.Write(Level.Debug, "Communication channel faulted..");

        //something went wrong
        this._proxy.Abort();
        this._proxy.InnerChannel.Faulted -= this.InnerChannel_Faulted;
        this._proxy.InnerChannel.Closing -= this.InnerChannel_Closing;

        //give the server a chance to get back online; retry after 10s
        Thread.Sleep(10000);

        //re-initialize the communication channel
        this.InitializeCommunicationChannel();
    }

我遇到的问题是,当客户端的配置文件中未正确配置服务器地址时,当我尝试发送Connect消息时,通道出现故障,但没有异常被捕获。 / p>

这是因为连接发生在另一个线程上,因此它永远不会在我的catch代码中结束吗?如何在代码中捕获端点配置异常? InnerChannel_Faulted的{​​{1}}成员不包含任何有用的信息。

非常感谢。
