我正在开发一个连接数据库的wcf服务。我调试并测试了我的操作播放器注册和俱乐部注册。然后我尝试测试get函数但我收到错误：
错误1＆＃39; WebApplication1.ADOService＆＃39;没有实现接口成员＆＃39; WebApplication1.IADOService.newMembership（WebApplication1.playerDetails，WebApplication1.playerDetails，WebApplication1.clubDetails，WebApplication1.memberDetails）＆＃39; C：\ Users \ Daniel \ Documents \ Visual Studio 2013 \ Projects \ Prac4 \ WebApplication1 \ ADOService.svc.cs 14 18 WebApplication1
发生错误后我试图删除get函数，但错误仍然存在。以下是服务代码

我假设get函数是问题的原因，但不确定如何解决错误。
答案 0 :(得分：2)
您已在界面中定义了以下方法：
string playerRegistration(playerDetails playerInfo);
string clubRegistration(clubDetails clubInfo);
List<playerDetails> getplayerInfo(string pfname, string plname);
List<clubDetails> getclubInfo(string cname);
string newMembership(playerDetails pfname, playerDetails plname, clubDetails cname, memberDetails memberstart);
但只实施了四个：
playerRegistration
clubRegistration
getplayerInfo
getclubInfo
您尚未在newMembership课程中实际实施ADOService。
