Question

当我浏览到IIS中的.svc页面时出现此错误 [即。 http：//localhost/PTSNew/PTNewService.svc ]。请问您如何解决此错误？并且，baseAddress属性中给出的url是否不正确？谢谢。

服务'PTSNew.PriceTestingService'没有应用程序（非基础设施）端点。这可能是因为没有配置找到了您的应用程序的文件，或者因为没有服务元素匹配服务名称可以在配置文件中找到，或者因为没有在服务元素中定义端点。

继承我的界面和app.config xml：

namespace PTSNew 
{ 
    // NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in App.config.

        public class PriceTestingService : IPriceTesting, IDisposable
}

namespace PTSNew 
{ 
    // NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in App.config.

    [ServiceContract] 
    public interface IPriceTesting 
}

Answer 1

您似乎忘记为服务元素编写合同属性

请转到http://www.codeproject.com/KB/WCF/first_WCF_Service.aspx查看示例

Answer 2

如果您在IIS上托管它，我认为您应该将配置放在web.config文件而不是app.config。

当您在IIS上托管WCF时，将忽略baseAddress。基地址由放置WCF服务的网站和Web应用程序地址确定。

Answer 3

您的服务合同（IPriceTesting）不公开任何方法。您需要向接口添加方法并使用OperationContract属性对其进行装饰。之后，您需要在服务类（PriceTestingService）中实现这些方法。

示例：

[ServiceContract]
public interface IPriceTesting
{
    [OperationContract]
    decimal GetPrice(int productId);
}

和

public class PriceTestingService : IPriceTesting
{
    public decimal GetPrice(int productId)
    {
        //TODO: implement the method body
        throw new NotImplementedException();
    }
}

为什么我收到WCF错误？
