asp.net - 解析会员提供者的值时出错

Question

当我尝试将值从我的成员资格类传递到我的存储库类时，我尝试使用成员资格提供程序和存储库类创建登录系统，该值可以通过..

我的代码有什么问题？？

namespace XNet.Services
{
    public class MembershipProviderService:IMembershipProviderService
    {
        IEntityRepository<User> _UserRepository;

        public MembershipProviderService(IEntityRepository<User> _UserRepository)
        {
            this._UserRepository = _UserRepository;
        }
        public MembershipProviderService()
        {

        }
        public User GetDataLogin(string UserName, string Password)
        {
            //List<User> GetData = _UserRepository.AsQueryable().Where(x => x.UserName == UserName && x.UserPassword == Password).ToList();
            var x = (from d in _UserRepository.All()
                     where d.UserName == UserName && d.UserPassword == Password
                     select d).FirstOrDefault();
            return x;

如果您在 ValidateUser 中收到 NullReferenceException，我猜想 _membershipProviderService 为空。你能验证吗？如果是这样，我猜问题是默认构造函数没有实例化_membershipProviderService。

你需要这样的东西：

public XNetMembership() : 
   this(new XNetMembershipProvider())
{

}

我的猜测是这条线失败了：

var x = _membershipProviderService.GetDataLogin(username, password);

在这里放一个断点，看看 _membershipProviderService 的值是多少。它是空的吗？那是你的问题。

从您的评论来看，您的问题似乎与 Ninject 相关。

Ninject 不应仅限于您的控制器。如果您有一个依赖于存储库的服务，为什么不在那里也使用 Ninject 呢？它的工作原理与控制器完全相同。然后你就可以轻松测试了。

要解决此问题，您需要与您的成员资格提供商做同样的事情来连接依赖关系，就像您连接控制器一样。我对 Ninject 不熟悉，但也许您在某些配置文件中缺少绑定或属性？

就像是：

kernel.Bind<IMembershipProviderService >().To<MyAwesomeMembershipProviderService>();
