Could not find default endpoint element that references contract-这是什么错误??

Could not find default endpoint element that references contract 'eUtils.eUtilsServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

应该不是，配置的问题的，直接引用就可以，多半是机器原因
