WCF服務 - 消息/對象大小相關

Question

我有wcf服務（S1）作爲客戶端，另一個Wcf服務（S2）作爲服務器。 S1通過net.tcp消耗S2。 S2有一個操作，它返回一個複雜的對象，其大部分內容都是字符串。該對象的平均大小在7-8 MB之間。

最近我不得不添加更多的字符串內容到實際的對象圖。這導致S2返回以下錯誤

套接字連接被中止。這可能是由於處理您的消息的錯誤 或遠程主機的 接收超時或基礎網絡資源問題所致。本地套接字 超時時間爲'00：05：00'。 System.Net.Sockets.SocketException （0x80004005）：現有連接被System.Net.Sockets.Socket.Receive（Byte []緩衝區，Int32 偏移量，Int32大小，SocketFlags socketFlags）上的遠程 主機強制關閉 System.ServiceModel.Channels.SocketConnection.ReadCore（字節[]緩衝液， 的Int32偏移的Int32大小，時間跨度超時，布爾閉合）

然而，一切都按預期，當我從刪除一些的字符串內容對象圖。

在做了一點家庭作業後，我得到了一個結論，它與返回的對象的大小有關。這使我修改了我的客戶端和服務配置/配額。

但是，即使修改客戶端和服務特別是大小相關的屬性後，我仍然沒有運氣。

有人可以指導我嗎？如有需要，請向我諮詢更多信息。

在此先感謝。

更新：按照@ ErikFunkenbusch的合理支持，我附上服務跟蹤信息。

Answer 1

您是否嘗試過增加發送和接收超時值？您通過網絡發送大量數據（7-8MB），並且5秒可能沒有足夠的時間來完成該事務。嘗試將它們設置爲30秒，然後從那裏開始工作。

E：

<binding name="netTcp" closeTimeout="00:30:00" 
     openTimeout="00:30:00" receiveTimeout="00:30:00" sendTimeout="00:30:00"> 

這就是我指的是，具體。
