Question

我使用以下代码段通过使用以下代码段从WCF服务获取数据。

 EmployeeServiceClient serviceClient=new EmployeeServiceClient();
            serviceClient.GetDataCompleted += new EventHandler<GetDataCompletedEventArgs>(serviceClient_GetDataCompleted);
            serviceClient.GetDataAsync(5);

但我在如何解决此问题上遇到以下异常。

System.ArgumentException occurred
  Message=The provided URI scheme 'http' is invalid; expected 'https'.
Parameter name: via
  StackTrace:

       at GridDataControlSilverlightWCFService.ServiceReference1.EmployeeServiceClient.EmployeeServiceClientChannel..ctor(ClientBase`1 client)
  InnerException:

我的确切要求将数据从服务加载到Silverlight主项目。你能帮忙解决一下吗。提前谢谢你。
