c# - 在 WCF 服务上运行 svcutil.exe 时出现 OperationBehaviorAttribute 错误

Question

当我尝试在 WCF 服务上运行 svcutil.exe 时，我遇到了一个非常奇怪的错误。

"OperationBehaviorAttribute can only go on the service class"

[InvalidOperationException]: OperationBehaviorAttribute can only go on the service class, it cannot be put on the ServiceContract interface. Method 'EditProduct' on type 'IProductWCF' violates this."

我已经在下面粘贴了我的代码，如果有人能对此有所说明，我将不胜感激。

我应该指出它适用于除“EditOpportunityProductTypes”之外的所有方法

我的界面:

namespace ProductWCF
{
    [ServiceContract]
    public interface IProductWCF
    {
        [OperationContract]
        string SayHello(AppointmentFeedback objAppointmentFeedback);

        [OperationContract]
        Boolean CreateAppointmentFeedback(AppointmentFeedback objAppointmentFeedback);

        [OperationContract]
        List<ExpiringContractType> GetOpportunityProductTypes(int opportunityId);

        [OperationBehavior]
        Boolean EditOpportunityProductTypes(List<ExpiringContractType> lstExpiringContractTypes, int opportunityId);
    }
}

我的服务:

namespace ProductWCF
{
    public class Service : IProductWCF
    {
        [OperationBehavior]
        public string SayHello(AppointmentFeedback objAppointmentFeedback)
        {
            return objAppointmentFeedback.Notes;
        }

        [OperationBehavior]
        public Boolean CreateAppointmentFeedback(AppointmentFeedback objAppointmentFeedback)
        {    
            ProductData.CRM.Objects.AppointmentFeedback objNewAppointmentFeedback = new AppointmentFeedback();    
            if (objNewAppointmentFeedback.Insert(objAppointmentFeedback.AppointmentId, objAppointmentFeedback.StarId, objAppointmentFeedback.AppointmentStatusId, objAppointmentFeedback.Notes, objAppointmentFeedback.Creator, objAppointmentFeedback.AttendeeName) > 0)
                return true;
            else
                return false;
        }

        [OperationBehavior]
        public List<ExpiringContractType> GetOpportunityProductTypes(int opportunityId)
        {    
            return OpportunityProductTypeMethods.GetOpportunityConnectionTypes(opportunityId);
                      
        }

        [OperationBehavior]
        public Boolean EditOpportunityProductTypes(List<ExpiringContractType> lstExpiringContractTypes, int opportunityId)
        {
            return ProductData.CRM.Objects.OpportunityProductTypeMethods.UpdateOpportunityConnectionTypes(lstExpiringContractTypes, opportunityId);
        }
    }
}

您已经使用 OperationBehavior 属性修饰了 interface 中的 EditOpportunityProductTypes 方法:

 [OperationBehavior]
 Boolean EditOpportunityProductTypes(List lstExpiringContractTypes, int opportunityId);

你可能打算在那里使用 OperationContract:

 [OperationContract]
 Boolean EditOpportunityProductTypes(List lstExpiringContractTypes, int opportunityId);
