与多个终结点的 WCF 通信

Question

>我有一个问题。我尝试构建具有多个入口点的 WCF 通信。但它永远不会起作用，它会显示如下错误消息：

• 在服务"{1}"实现的协定列表中找不到协定名称"{0}"。

这是我的配置文件：

有人知道我是否配置错误吗？

亲切问候。

您要么尚未实现以下接口之一：MwWcfLibrary.Actions.Interfaces.IAction、MwWcfLibrary.LifeSign.Interfaces.ILifeSign、MwWcfLibrary.PublicData.Interfaces.IPublicData和MwWcfLibrary.PublicState.Interfaces.IPublicState

或者其中一个或多个未使用[ServiceContract]属性进行修饰

在你的问题中包含实际错误而不是"{0}"，你会看到你的一些合约没有被类Service实现，它应该看起来像这样(至少(：

class Service : IAction, ILifeSign, IPublicData, IPublicState
{
// implementation
}

此外，您的地址属性似乎不正确，因为您已经定义了一个以段//Mww 结尾的基址...，但在您的端点中，地址比基址短。端点地址可以是相对的，如"Service".

以前

Service元素是指一个类，该类是ServiceContract接口的实现，这是进入endpoint协定属性的内容。验证这些属性中接口和类的完全限定名称。

从你的配置文件来看，你说类MwWcfLibrary.Service实现了称为MwWcfLibrary.Actions.Interfaces.IAction、MwWcfLibrary.LifeSign.Interfaces.ILifeSign、MwWcfLibrary.PublicData.Interfaces.IPublicData和MwWcfLibrary.PublicState.Interfaces.IPublicState的([ServiceContract]装饰的(接口

。这似乎是错误的。您的意思是有两个服务，每个服务都有一个单独的终结点？
