Question

我的WCF服务[使用basicHttpBinding]托管在IIS 6.Am能够使用IE浏览器服务URL中的？wsdl访问它。

我在winforms客户端中有一个presenation层，我在VS.Net中使用ServiceReferences选项添加了此服务的引用，然后生成了代理。

当我在这个服务上调用一个方法时，我得到了这个异常。我可以在这里找到什么？谢谢。

“值不能为null。参数名称为uri。”在   System.ServiceModel.Description.ClientViaBehavior..ctor（Uri uri）
  在System.ServiceModel.Configuration.ClientViaElement.CreateBehavior（）   在   System.ServiceModel.Description.ConfigLoader.LoadBehaviors [T]（ServiceModelExtensionCollectionElement 1 behaviorElement, KeyedByTypeCollection 1行为，布尔值   commonBehaviors）

在   System.ServiceModel.Description.ConfigLoader.LoadChannelBehaviors（ServiceEndpoint   serviceEndpoint，String configurationName）

at System.ServiceModel.ChannelFactory.ApplyConfiguration（String   configurationName）at   System.ServiceModel.ChannelFactory.InitializeEndpoint（字符串   configurationName，EndpointAddress地址）at   System.ServiceModel.ChannelFactory 1..ctor(String endpointConfigurationName, EndpointAddress remoteAddress) at System.ServiceModel.EndpointTrait 1.CreateSimplexFactory（）at   System.ServiceModel.EndpointTrait 1.CreateChannelFactory() at System.ServiceModel.ClientBase 1.CreateChannelFactoryRef（EndpointTrait 1 endpointTrait) at System.ServiceModel.ClientBase 1.InitializeChannelFactoryRef（）at   System.ServiceModel.ClientBase`1..ctor（）at   C：\ Presentation \ Service中的TestingClient..ctor（）   参考文献\ ServiceReference1 \ Reference.cs：第268行

这是我的服务器和客户端的配置xml：

Answer 1

在客户端配置行为中，您有一个没有定义任何URI的ClientVia元素。删除此行为或定义via Uri。

这很好地解释了客户端行为的目标和用法：http://blogs.msdn.com/b/anilkumargupta/archive/2009/05/16/wcf-intermediate-service-between-client-and-server.aspx

这个WCF错误的原因是什么？
