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

_PasswordStrengthRegularExpression = Convert.ToString( GetConfigValue(config["passwordStrengthRegularExpression"], "")); } } iTwitterMembershipUser.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Security; using iTwitter.Models; namespace iTwitter.Models { public class iTwitterMembershipUser : MembershipUser { private string _tokenKey; private string _tokenSecret; private string _twitterUserId; private string _login; private string _email; private int _providerUserKey; public string tokenKey { get { return _tokenKey; } set { _tokenKey = value; } } public string tokenSecret { get { return _tokenSecret; } set { _tokenSecret = value; } } public string twitterUserId { get { return _twitterUserId; } set { _twitterUserId = value; } } public string login { get { return _login; } set { _login = value; } } public string email { get { return _email; } set { _email = value; } } public int providerUserKey { get { return _providerUserKey; } set { _providerUserKey = value; } } public iTwitterMembershipUser(object providername, string login, int providerUserKey, string email, string tokenKey, string tokenSecret, string twitterUserId) { this.tokenKey = tokenKey; this.tokenSecret = tokenSecret; this.twitterUserId = twitterUserId; this.login = login; this.providerUserKey = providerUserKey; this.email = email; } } }
webconfig.cs
iTwitterDB：
id int login varchar(50) password varchar(100) (MD5 Password Hash) email varchar(100) tokenKey varchar(100) tokenSecret varchar(100) twitterUserId varchar(100)
UserRepository.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Security; namespace iTwitter.Models { public class UserRepository { public iTwitterMembershipUser CreateUser(string login, string password, string email) { using (iTwitterDB db = new iTwitterDB()) { Users user = new Users(); user.login = login; user.email = email; user.password = password; user.tokenKey = "0"; user.tokenSecret = "0"; user.twitterUserId = "0"; db.AddToUsers(user); db.SaveChanges(); return GetUser(login); } } public string GetUserNameByEmail(string email) { using (iTwitterDB db = new iTwitterDB()) { var result = from u in db.Users where (u.email == email) select u; if (result.Count() != 0) { var dbuser = result.FirstOrDefault(); return dbuser.login; } else { return ""; } } } public iTwitterMembershipUser GetUser(string login) { using (iTwitterDB db = new iTwitterDB()) { var result = from u in db.Users where (u.login == login) select u; if (result.Count() != 0) { var dbuser = result.FirstOrDefault(); string _login = dbuser.login; int _providerUserKey = dbuser.id; string _email = dbuser.email; string _tokenKey = dbuser.tokenKey; string _tokenSecret = dbuser.tokenSecret; string _twitterUserId = dbuser.twitterUserId; iTwitterMembershipUser user = new iTwitterMembershipUser("CustomMembershipProvider", _login, _providerUserKey, _email, _tokenKey, _tokenSecret, _twitterUserId); return user; } else { return null; } } } } }
我在编译期间遇到了一些错误：
1) 'iTwitterMembershipProvider' does not implement inherited abstractmember’System.Web.MembershiProvider.CreateUser（string，string，string，string，string，bool，object，out System.Web.Security.MembershipCreateStatus）’
2) iTwitterMembershipProvider.CreateUser(string,string，string，string，string，bool，object，out 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’才能匹配被覆盖的成员’System.Web.Security.MembershipProvider.GetUser（string，bool）’
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。 如果实现接口，或者使用抽象方法从类inheritance，那么您的类必须提供这些成员的实现。 在您的情况下，返回类型与抽象方法的返回类型不匹配。
