我创建了一个简单的 web 服务服务器,但是为了从同一个项目中的服务类调用方法,我创建了一个 webchannelfactory 代理。在我将项目(或 exe 版本)移动到另一台机器之前,一切正常。我无法弄清楚这是怎么回事!
我收到此错误消息:
The remote server returned an unexpected response: (400) Bad Request.
使用堆栈跟踪:

代码:
WebChannelFactory<Client.IClientService> factory = new WebChannelFactory<Client.IClientService>(hostUri);
Client.IClientService proxy = factory.CreateChannel();
proxy.dosomething(); // Error shout here on Machine2
提前致谢
EDIT1:对于这个例子,没有客户端(我已经将客户端命名为这个服务器)。正如我所说,它在另一台机器上运行的代码没有错误(都使用本地主机)。

编辑2:
在浏览器上,我得到了这个:
服务器在处理请求时遇到错误。异常消息是“'Client.ClientService' 的类型初始化程序引发了异常。”。有关更多详细信息,请参阅服务器日志。异常堆栈跟踪是:
