Question

您好，

我在IIS中托管了一个WCF服务，该服务具有以下绑定配置：

 <binding name="netTcpRegular" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:00:20" sendTimeout="00:20:00" transactionFlow="false" transferMode="Buffered" transactionProtocol="OleTransactions" hostNameComparisonMode="StrongWildcard" listenBacklog="10" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxConnections="10" maxReceivedMessageSize="2147483647">
          <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <reliableSession ordered="true" inactivityTimeout="infinite" enabled="false"/>
          <security mode="None">
            <transport clientCredentialType="None" />
          </security>
        </binding>

当客户端（保持频道开放）已经登录到WCF服务时，频道将在20 secon之后抛出故障异常并且我没有做任何事情，甚至没有与服务进行交流？因此，在20秒不活动后，通信将失败。

receiveTimeout应该只影响正在进行的通话吗？那么除了让频道打开并准备好进行服务呼叫之外什么都不做的时候怎么能有所提高呢？

通过使用WCF日志，我得到了以下例外情况：

Answer 1

你错过了对meaning of ReceiveTimeout的理解。它是“连接可以保持非活动状态的时间间隔，在此期间，在删除之前不会收到任何应用程序消息”。要将此扩展到无穷大，您需要enable reliable sessions。希望这可以解决它。

编辑： Here是进一步的描述，我认为您所追求的属性是sendtimeout

Answer 2

接收超时是指等待接收所有数据的时间。

一旦chanel打开，时间就开始运行，它不会检测到你发送的第一个字节，然后启动计时器。

有点像出租车，当你挥动它时启动仪表，而不是当你进入时。

receiveTimeout在不活动后中断通信通道？
