实现自定义 MembershipUser

Question

我正在兜圈子，需要一些帮助来实现自定义 MembershipUser，以便我可以将自己的自定义属性添加到 MembershipUser。

我一直在关注这个网站上的例子：How to: Implement a Custom Membership User

我认为我遇到的问题出在 CustomMembershipUser 的构造函数中。

我的 CustomMembershipUser 具有以下三个附加属性：firstName、middleName、lastName。

public class CustomMembershipProvider : MembershipProvider
{
  public override MembershipUser GetUser(string username, bool userIsOnline)
    {
       //.... Get data from database
       MembershipUser baseUser = new MembershipUser(this.Name,
                                               username,
                                               userId,
                                               email,
                                               "",
                                               comment,
                                               isApproved,
                                               isLockedOut,
                                               dtCreate,
                                               dtLastLogin,
                                               dtLastActivity,
                                               DateTime.Now,
                                               dtLastLockoutDate);
                    return new CustomMembershipUser(baseUser, firstName, middleName, lastName)
    }
}


public class CustomMembershipUser : MembershipUser
{
  private string _firstName;
    public string FirstName { get { return _firstName; } set { _firstName = value; } }

    private string _middleName;
    public string MiddleName { get { return _middleName; } set { _middleName = value; } }

    private string _lastName;
    public string LastName { get { return _lastName; } set { _lastName = value; } }

 public CustomMembershipUser(MembershipUser baseuser, string firstname, string middlename, string lastname)
    {
        _firstName = firstname;
        _middleName = middlename;
        _lastName = lastname;

        new CustomMembershipUser(baseuser); // DO I NEED THIS?? HOW TO IMPLEMENT??
        
    }
}

我这样称呼它：

    MembershipUser mu = Membership.GetUser(UserName);

    CustomMembershipProvider p = (CustomMembershipProvider)Membership.Provider;
    
    MembershipUser memUser = p.GetUser(UserName, true);

    object userId = memUser.ProviderUserKey;

ProviderUserKey 为空，其他值也是如此。

如何获取我添加的附加属性？

谢谢

这对我有用：

public class CustomMembershipUser : MembershipUser
{
    public CustomMembershipUser(
        string providerName,
        string name,
        object providerUserKey,
        string email,
        string passwordQuestion,
        string comment,
        bool isApproved,
        bool isLockedOut,
        DateTime creationDate,
        DateTime lastLoginDate,
        DateTime lastActivityDate,
        DateTime lastPasswordChangedDate,
        DateTime lastLockoutDate
        )
        : base(providerName, name, providerUserKey, email, passwordQuestion,
        comment, isApproved, isLockedOut, creationDate, lastLoginDate,
        lastActivityDate, lastPasswordChangedDate, lastLockoutDate)
    {
    }

    // Add additional properties
    public string CustomerNumber { get; set; }

}

public class CustomMembershipProvider : MembershipProvider
{

    public override MembershipUser GetUser(string username, bool userIsOnline)
    {
        if (string.IsNullOrEmpty(username))
        {
            // No user signed in
            return null;
        }

        // ...get data from db

        CustomMembershipUser user = new CustomMembershipUser(
                    "CustomMembershipProvider",
                    db.Username,
                    db.UserId,
                    db.Email,
                    "",
                    "",
                    true,
                    false,
                    db.CreatedAt,
                    DateTime.MinValue,
                    DateTime.MinValue,
                    DateTime.MinValue,
                    DateTime.MinValue);

        // Fill additional properties
        user.CustomerNumber = db.CustomerNumber;

        return user;

    }

}

// Get custom user (if allready logged in)
CustomMembershipUser user = Membership.GetUser(true) as CustomMembershipUser;

// Access custom property
user.CustomerNumber

您知道，我之前尝试过使用 MembershipProvider 路径，但这条路径又长又多风。您可能会发现仅创建实现 IPrincipal 和 IIdentity 的类是否能满足您的需求，因为它们需要的开销要少得多。

Answer 3

根据我自己尝试做很多相同的经验，尝试使用 MembershipProvider 来做这件事最终将是一种令人沮丧和违反直觉的体验。

会员提供者模型的想法不是改变或增加用户的定义，正如您正在尝试做的那样 - 它是允许框架以替代方式访问已经存在的信息定义为属于“MembershipUser”。

我认为您真正需要的是用户个人资料。使用 ASP.NET 配置文件比实现您自己的提供程序更容易。 You can find the overview here.
