实现Custom MembershipUser和Custom MembershipProvider

我尝试在我自己的数据库中使用Custom MemberShipUser实现Custom MembershipPriver（具有特定的用户表模型）： 这是不同的文件： iTwitterMembershipProvider.cs 
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Collections.Specialized;
using iTwitter.Models;


 public class iTwitterMembershipProvider : MembershipProvider

    public override string ApplicationName

        set { _ApplicationName = value; }
    }

    public override bool ChangePassword(string username, string oldPassword, string newPassword)
    {
        throw new NotImplementedException();

编译时我遇到了一些错误： 
1) 'iTwitterMembershipProvider' does not implement inherited abstract
     会员   “System.Web.MembershiProvider.CreateUser（字符串，   string，string，string，string，bool，   对象，出来   System.Web.Security.MembershipCreateStatus）”

     string，string，string，string，bool，   对象，出来   System.Web.Security.MembershipCreateStatus）“：   找不到合适的方法来覆盖 
3)'iTwitterMembershipProvider.GetUser(string,
     bool）'：返回类型必须是   'System.Web.Security.MembershipUser'   匹配被覆盖的成员   “System.Web.Security.MembershipProvider.GetUser（字符串，   布尔）” 我在这里被封锁了。 谢谢。

    将CreateUser和GetUser的返回类型更改为基类MembershipUser。当您调用这些方法时，您可以将其强制转换为iTwitterMembershipUser类型。例如，在CreateUser中，将return语句更改为 
    return (iTwitterMembershipUser) GetUser(login);

    自从我查看MembershipProvider的内容已经有很长一段时间了，我不记得所有接口了。但是你的错误是关于你正在实现一个抽象基类的事实，它具有你没有实现的抽象方法。如果您实现接口，或者使用抽象方法从类继承，那么您的类必须提供这些成员的实现。在您的情况下，您的返回类型与抽象方法的返回类型不匹配。
