你好，

我有一个托管在 IIS 中的 WCF 服务，它具有以下绑定配置：

 <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（保持通道打开）登录到 WCF 服务时，通道将在 20 秒后抛出错误异常，而我什么也不做，甚至没有与服务通信？因此，在 20 秒不活动后，通信将失败。

receiveTimeout 应该只影响通话进行的时间，对吗？那么，除了让通道打开并准备好进行服务调用之外什么都不做时，它怎么会超时呢？

通过使用 WCF 日志，我得到了以下异常：

客户端绑定：

您误解了 ReceiveTimeout 的含义。它是“连接可以保持非活动状态的时间间隔，在此期间没有收到应用程序消息，然后断开连接”。要将其扩展到无穷大，您需要启用可靠会话。希望这可以清除它。

编辑： 这是进一步的描述，我认为您所追求的属性是 sendtimeout

接收超时是等待接收所有数据的时间。

通道一打开，时间就开始运行，它不会检测到您发送的第一个字节，然后启动计时器。

这有点像出租车，在你挥手时启动计程器，而不是在你上车时。
