System.ServiceModel.EndpointNotFoundException：没有端点监听

Question

我在 Visual Studio 中有一个新的 WPF 项目。我想连接到这个网址：“http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL”。

我已提供服务参考。

当我运行它时，我得到了这个错误（我已将文本翻译成英文）：

System.ServiceModel.EndpointNotFoundException
  HResult=0x80131501
  Message=There was no endpoint listening at http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso, that can accept the message. This is often because of a wrong address or SOAP-action. Find more information at InnerException.

Answer 1

我发现问题在于我的 Visual Studio 解决方案位于网络驱动器上（Windows 将其称为“K”）。当我将解决方案移至 C 盘时，它运行良好。

感谢您的宝贵时间！

Answer 2

在我创建一个新控制台并测试您提供的 URL 后，它运行良好。
调用服务的代码段和你上面贴的一样，包括Appconfig文件中的服务端点。
结果。

两个端点都能正常工作，我什至用自定义绑定测试端点。

ServiceReference1.CountryInfoServiceSoapTypeClient client = new
ServiceReference1.CountryInfoServiceSoapTypeClient("CountryInfoServiceSoap12");
MyLabel.Content = client.CapitalCity("US");

因此，我怀疑您的本地网络连接有问题。
建议你关闭本地防火墙、杀毒软件、本地Hosts文件，用Ping命令查明问题所在，查看该机浏览器是否可以访问该URL。
如果问题仍然存在，请随时告诉我。
