我如何从Windows服务调用webservice

Question

我有一个Windows服务，我试图在远程webservice下调用一个方法，但是我收到错误“无法在ServiceModel客户端配置部分找到引用契约'MyWebService.BookingCitySoap'的默认端点元素。这可能因为没有为您的应用程序找到配置文件，或者因为在客户端元素中找不到与此合同匹配的端点元素。“

以下是该

的代码

.cs文件

MyWebService.BookingCitySoapClient ws = new MyWebService.BookingCitySoapClient();

                ws.CallBookStatus();

                ws.CallCanStatus();

的App.config

        <basicHttpBinding>
