WCF超时问题

我有以下代码WCF超时问题

public bool StartWCF() 
    { 
     try 
     { 
      // Select the first entry. I hope it's this maschines IP 
      // IPAddress _ipAddress = ips.AddressList[0]; 
      var ipAddress = new IPAddress(new byte[] { 127, 0, 0, 1 }); 

      // Create the url that is needed to specify where the service should be started 
      this.m_UrlMetaServiceComm = "net.tcp://" + ipAddress + ":8000/VSMDBCommunication"; 
      this.m_UrlMetaServicePart = "net.tcp://" + ipAddress + ":8000/VSMDBPartType"; 

      string endPointAddrComm = this.m_UrlMetaServiceComm; 
      var tcpBindingComm = new NetTcpBinding 
       { 
        TransactionFlow = false, 
        MaxReceivedMessageSize = 20000000, 
        MaxBufferSize = 20000000, 
        MaxBufferPoolSize = 20000000, 
        ReaderQuotas = { MaxNameTableCharCount = 20000000 }, 
        OpenTimeout = new TimeSpan(0, 5, 0), 
        SendTimeout = new TimeSpan(0, 5, 0), 
        CloseTimeout = new TimeSpan(0, 5, 0) 
       }; 
      tcpBindingComm.Security.Transport.ProtectionLevel = ProtectionLevel.EncryptAndSign; 
      tcpBindingComm.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; 
      tcpBindingComm.Security.Mode = SecurityMode.None; 

      var endpointAddressComm = new EndpointAddress(endPointAddrComm); 
      this.m_ChannelCommunication = ChannelFactory<IVSMDBCommunication>.CreateChannel(
       tcpBindingComm, endpointAddressComm); 
      ((IContextChannel)m_ChannelCommunication).OperationTimeout = new TimeSpan(0, 5, 0); 
      string endPointAddrPart = this.m_UrlMetaServicePart; 
      var tcpBindingPart = new NetTcpBinding 
       { 
        TransactionFlow = false, 
        MaxReceivedMessageSize = 20000000, 
        MaxBufferSize = 20000000, 
        MaxBufferPoolSize = 20000000, 
        ReaderQuotas = { MaxNameTableCharCount = 20000000 }, 
        OpenTimeout = new TimeSpan(0, 5, 0), 
        SendTimeout = new TimeSpan(0, 5, 0), 
        CloseTimeout = new TimeSpan(0, 5, 0) 
       }; 
      tcpBindingPart.Security.Transport.ProtectionLevel = ProtectionLevel.EncryptAndSign; 
      tcpBindingPart.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows; 
      tcpBindingPart.Security.Mode = SecurityMode.None; 

      var endpointAddressPart = new EndpointAddress(endPointAddrPart); 
      this.m_ChannelPartTypes = ChannelFactory<IVSMDBPartType>.CreateChannel(
       tcpBindingPart, endpointAddressPart); 
      ((IContextChannel)m_ChannelPartTypes).OperationTimeout = new TimeSpan(0, 5, 0); 
      return true; 
     } 
     catch (CommunicationObjectFaultedException faultEx) 
     { 
      // System.Diagnostics.Trace.TraceError(faultEx.ToString()); 
      Console.WriteLine("An unknown exception was received. " + faultEx.Message + faultEx.StackTrace); 
      Console.Read(); 
      return false; 
     } 
     catch (EndpointNotFoundException endEx) 
     { 
      // System.Diagnostics.Trace.TraceError(endEx.ToString()); 
      Console.WriteLine("An unknown exception was received. " + endEx.Message + endEx.StackTrace); 
      Console.Read(); 
      return false; 
     } 
    }

，我偶尔会碰到下面的错误当底层过程需要超过一分钟。

消息：

发送到的net.tcp此请求操作：//127.0.0.1：8000/VSMDBCommunication 没有收到配置的超时（00:01:00）中的答复。分配给此操作的时间可能是已超时的更长时间的一部分。这可能是因为服务仍在处理操作或因为服务是无法发送答复消息。请考虑增加操作超时（通过强制通道/代理转换为IContextChannel和设置OperationTimeout属性），并确保该服务能够连接到客户端。

如何以不同于我为避免此错误的方式来投射频道，这很有意义，因为底层请求可能需要一分多钟才能计算。

尝试设置ReceiveTimeout属性。

这似乎没有解决问题。 – PlTaylor 2011-02-24 18:48:36

设置客户端操作超时为

client.InnerChannel.OperationTimeout = TimeSpan.FromMinutes(10);

这将删除你的错误。
