錯誤從.NET客戶端

Question

連接到WCF服務我在VS 2010

創建了一個新的WCF項目，默認模板然後我創建了一個控制檯應用程序作爲一個客戶端連接到WCF服務。

這裏是我用來連接到服務代碼：

ServiceReference1.Service1Client client = new ServiceReference1.Service1Client(); 

CompositeType ctype = client.GetDataUsingDataContract(new CompositeType()); 

當代碼獲取到它試圖調用該方法GetDataUsingDataContract（），我得到以下異常：

Error creating the Web Proxy specified in the 'system.net/defaultProxy' configuration section.

我知道有沒有錯SE服務器和客戶端，因爲我將它複製到另一臺機器上，並且它連接起來，稱爲方法，並返回結果沒有問題。

在我的本地機器上有一些設置阻止我連接到此服務？

請幫忙!!!

謝謝

Answer 1

服務託管在哪裏，它是否在IIS的另一臺機器上運行？該服務是否由Visual Studio的開發Web服務器Casini託管運行？

如果它由IIS託管，客戶端上的瀏覽器是否可以通過「開心您創建服務消息」來從服務器查看.svc文件？

嘗試使用Service Trace Viewer來追蹤你的問題。

一旦你的日誌生成並加載到查看器中，你會發現這個問題很快。這個問題可以是任何不妥協的配置，數據對象不能正確序列化爲WCF代碼中引發的異常。

好，閱讀錯誤消息：

錯誤創建代理 在 'system.net/defaultProxy' 配置部分中指定的Web。

所以 - 你能告訴我們在你的web.config文件中定義的<system.net>/<defaultProxy>的值嗎？最有可能的東西有點腥......
