我在使用我的WCF服務時遇到問題。我在控制檯應用程序中使用了我的WCF服務,它可以正常工作,直到100個請求(在一個循環中)。但它在100次請求後停止工作。我已經在我的配置中使用了WCF服務在100次調用後停止工作

<serviceThrottling 
        maxConcurrentCalls="500" 
        maxConcurrentInstances="500" 
        maxConcurrentSessions="500"/> 

但它對此問題沒有影響。每次調用服務後,我都關閉了連接,但問題仍然存在。

任何幫助,高度讚賞。

真的很傻什麼錯誤,你讓當您啓用FaultExceptions? –

嗨種兔, 作爲事實上,我沒有得到任何異常或者 我是新來的WCF,可能是我做錯了什麼: 公開名單 GetDestinationHotelId(字符串DestinationAirport) { 嘗試 { 包objPkg =新包(); 回報objPkg.GetDestinationHotelId(DestinationAirport);} catch(Exception fe) { throw new FaultException(fe.Message); } //返回null; } 以上是我的服務合同方法。 – kulesshhh

以下是我的客戶端應用程序代碼使用它: int x = 0; while(true) { x ++;使用(AirGainUtilities.Service.UtilitiesClient UC = new AirGainUtilities.Service.UtilitiesClient()) 列表 lstHotels = UC.GetDestinationHotelId(「SJD」);如果(lstHotels.Count <= 0) { x ++; } } } – kulesshhh

顯然,問題是在包裝類的GetDestinationHotelId方法的開放數據庫連接。 DB連接由於例外而未關閉,並且在打開100個連接後MAX CONNECTION POOL LIMIT已達到。

在我結束:-(
