Question

我创建了一个名为“ TPUSRER”的asp.net Web应用程序，并在其中添加了WCF服务，该服务实现了一个共享点在线远程事件接收器，这是我的代码：-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace TPUSRER
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public interface IService1
    {
        [OperationContract]
        void DoWork();
    }
}

和服务：-

namespace TPUSRER
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "RER" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select RER.svc or RER.svc.cs at the Solution Explorer and start debugging.
    public class Service1 : IRemoteEventService
    {
        public SPRemoteEventResult ProcessEvent(SPRemoteEventProperties properties)
        {
//code goes here

这是我的web.config：-

<?xml version="1.0" encoding="utf-8"?>

但是当我在天蓝色的内部部署此WCF时出现此错误：-

那么有人可以对此错误提出建议吗？谢谢

Answer 1

该错误表示您的类Service1应该实现您的接口IService1。您可以实现多个接口。

public class Service1 : IService1, IRemoteEventService

或者您的界面可以扩展IRemoteEventService，然后可以在ProcessEvent()中实现DoWork()和Service1。

[ServiceContract]
public interface IService1 : IRemoteEventService

在服务“ Service1”实施的合同列表中找不到合同名称“ TPUSRER.IService1”
