receiveTimeout閒置後中斷通信信道？

Question

嗨，

我在IIS具有以下綁定配置託管的WCF服務：

<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> 

當客戶端（即佔用信道開放）已經登錄到WCF服務頻道會在20秒後拋出一個錯誤的例外，我沒有做任何事情，甚至沒有與服務交流？所以在20秒鐘不活動之後，通信將失敗。

receiveTimeout應該只會影響正在進行調用的權利？那麼，它什麼時候什麼也不做，只能讓渠道開放並準備好接聽服務電話，它怎麼會這樣呢？

通過使用WCF登錄我得到這個異常：

Answer 1

您錯過了meaning of ReceiveTimeout。這是「連接可以保持非活動狀態的時間間隔，在這段時間內，沒有收到任何應用程序消息，而是在它被刪除之前」。要將此擴展到無窮大，您需要enable reliable sessions。希望這可以清除它。

編輯： Here進一步的描述，我覺得你是以後的財產的SendTimeout

Answer 2

接收超時是多長時間等待要接收的所有數據。

當chanel打開時，時間開始運行，它不檢測您發送的第一個字節，然後啓動計時器。

它有點像出租車，當你把它拉下來時啓動儀表，而不是當你進入。
