Question

使用MembershipProvider重新审视用户创建中的一些旧代码，我发现没有使用以下代码创建新用户：

// the call
Membership.CreateUser(user.Username, user.Password, user.EmailAddress, null, null, false, null, out createStatus);


    public override MembershipUser CreateUser(string username,
       string password, string email, string passwordQuestion,
       string passwordAnswer, bool isApproved,
       object providerUserKey, out MembershipCreateStatus status)
    {

        using (var db = new DbV001Context())
        {
            var crypto = new SimpleCrypto.PBKDF2();
            var encryptedPw = crypto.Compute(password);
            var user = db.Users.Create();

            user.MembershipTypeId = 7; 
            user.UserName = username;
            user.Email = email;
            user.Password = encryptedPw;
            user.PasswordSalt = crypto.Salt;
            //user.CreateDate = DateTime.Now; // set automatically in the db

            //user.CreateDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastLoginDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastActivityDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastPasswordChangedDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastLockoutDate = new DateTime(1980, 01, 01, 0, 0, 0, 0);

            db.Users.Add(user);
            try
            {
                db.SaveChanges();
            } ...

我在实现repository and UoW pattern之前编写了这部分代码，我在其他地方使用它：

    private readonly IUnitOfWork _unitOfWork;
    private readonly IRepository<User> _repository;

    public AccountController() { }

    public AccountController(IUnitOfWork unitOfWorkAsync,
        IRepository<User> repository)
    {
        _unitOfWork = unitOfWorkAsync;
        _repository = repository;
    }

   .
   .
   .
                var userEntity = _repository
                    .ODataQueryable()
                    .Where(u => (u.Email == user.EmailAddress | u.UserName == user.Username)
                                && u.Email != null).ToList();

我尝试了以下操作，但在尝试Insert()时仍然遇到异常：

public class CustomMembershipProvider : MembershipProvider
{
    //private DbV001Context _db = new DbV001Context();
    private readonly IUnitOfWork _unitOfWork;
    private readonly IRepository<User> _repository;

    public CustomMembershipProvider() { }

    public CustomMembershipProvider(IUnitOfWork unitOfWorkAsync,
        IRepository<User> repository)
    {
        _unitOfWork = unitOfWorkAsync;
        _repository = repository;
    }
    public override MembershipUser CreateUser(string username,
       string password, string email, string passwordQuestion,
       string passwordAnswer, bool isApproved,
       object providerUserKey, out MembershipCreateStatus status)
    {

        //using (var db = new DbContext())
        //{
            var crypto = new SimpleCrypto.PBKDF2();
            var encryptedPw = crypto.Compute(password);
            //var user = db.Users.Create();
            var user = new User();

            user.MembershipTypeId = 7; 
            user.UserName = username;
            user.Email = email;
            user.Password = encryptedPw;
            user.PasswordSalt = crypto.Salt;
            //user.CreateDate = DateTime.Now; // set automatically in the db

            //user.CreateDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastLoginDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastActivityDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastPasswordChangedDate = new DateTime(1980,01,01,0,0,0,0);
            user.LastLockoutDate = new DateTime(1980, 01, 01, 0, 0, 0, 0);


            //db.Users.Add(user);
            try
            {
                //db.SaveChanges();
                _repository.InsertGraph(user);  //Object reference not set to an instance of an object.
            }

因为我看了这些东西已经有一段时间了，我如何更新上面的代码来使用存储库，而不是数据库上下文？另外，既然我正在使用DI，那么在设置CustomMembershipProvider时我是否缺少某些内容？

当我单步执行代码时，CustomMembershipProvider构造函数未被执行。使用Autofac进行DI。

我不认为成员资格提供程序允许您在构造函数中提供参数...在您的参数less构造函数中，您可以为您的UOW和Repository分配当前实例，或者如果尚未完成则激活它们。< / p>

但这取决于你正在使用的DI框架。

如何更新此代码从使用EF db上下文到通用存储库？
