从.NET客户端连接到WCF服务时出错[已关闭]

我用VS2010中的默认模板创建了一个新的WCF项目。

然后我创建了一个控制台应用程序作为客户端连接到wcf服务。

下面是我用来连接服务的代码:

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

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

当代码到达它试图调用getDataUsingDataContract()方法的位置时,我得到以下异常:

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

                name="BasicHttpBinding_IService1" />
        </client>
    </system.serviceModel>
</configuration>

我知道服务和客户机没有问题,因为我将它复制到另一台机器上,然后它连接起来,调用方法,并返回结果,没有问题。

本地计算机上是否存在阻止我连接到此服务的设置?

请帮忙!!!

谢谢
