我使用VS 2010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,作为连接到WCF服务的客户端。
以下是我用来连接服务的代码:
ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
CompositeType ctype = client.GetDataUsingDataContract(new CompositeType());
当代码到达尝试调用方法GetDataUsingDataContract()的位置时,我得到以下异常:
Error creating the Web Proxy specified in the 'system.net/defaultProxy' configuration section.

我知道服务和客户端没有任何问题,因为我将它复制到另一台机器并连接,称为方法,并且没有任何问题返回结果。
我的本地计算机上是否有某些设置阻止我连接此服务?
请帮助!!!

好了,请阅读错误消息:
创建Web代理时出错 在...中指定 'system.net/defaultProxy' 配置部分。
那么 - 你能告诉我们你web.config中<system.net>/<defaultProxy>
中定义的值吗?最有可能是有些可疑的......

托管服务在哪里,例如它是否在IIS中的另一台机器上运行?服务是否由Casini(Visual Studio的开发Web服务器)托管运行?
如果它由IIS托管,客户端上的浏览器是否可以从服务器查看.svc文件,并且“您已经开心创建了服务消息”?

尝试使用Service Trace Viewer来追踪您的问题所在。
生成日志并将其加载到查看器后,您会很快发现问题。问题可能是从狡猾的配置到没有正确序列化的数据对象到WCF代码中抛出的异常。
