WCF c＃中自定義類的傳輸問題

Question

我正在服務器和客戶端之間傳輸數據。 客戶端很容易從服務器接收常規數據類型，例如int ，但是如果將自定義類傳遞給它，那么我將收到以下異常：

System.ServiceModel.CommunicationException：獲取HTTP響應http://127.0.0.1:8000/Service時發生錯誤。 這可能是由於服務端點綁定未使用HTTP協議這一事實造成的。 這也可能是由於HTTP請求上下文已被服務器中斷（可能是由於服務被禁用）所致。 有關詳細信息，請參見服務器日志。

我嘗試了許多解決方案來解決此類問題，但沒有任何幫助。 我在類字段中添加了getter和setter方法，將DataContract等更改為Serializable ：

Answer 1

托管服務后可以訪問Web服務的WSDL嗎？ 我懷疑配置可能太簡單了。 我建議您在服務器端應用以下配置。

  <system.serviceModel>
    <services>
      <service name="YourNamespace.GameServer " behaviorConfiguration="mybehavior">
        <endpoint address="http://localhost:8000/Service" binding="basicHttpBinding" contract="YourNamespace.IGame " ></endpoint>
        <endpoint address="http://localhost:8000/Service/mex" binding="mexHttpBinding" contract="IMetadataExchange"></endpoint>
      </service>
    </services>    
    <behaviors>
      <serviceBehaviors>
        <behavior name="mybehavior">
          <serviceMetadata httpsGetEnabled="true" httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

托管服務后，我們可以通過在瀏覽器地址欄中鍵入服務地址來訪問服務信息。

http://localhost:8000/service

此外，托管服務時，我們可能需要管理特權。 隨時讓我知道問題是否仍然存在。
