我已经按照本教程进行了很好的工作,直到我修改了我DbContext有一个额外的构造函数.我现在遇到了解决方案的问题,不知道如何解决这个问题.是否有一种简单的方法可以强制它抓住无参数构造函数,或者我接近这个错误？

DbContext 有两个构造函数:

public class DashboardDbContext : DbContext
{
    public DashboardDbContext() : base("DefaultConnection") { }

    public DashboardDbContext(DbConnection dbConnection, bool owns)
        : base(dbConnection, owns) { }
}

SiteController 构造函数:

private readonly IDashboardRepository _repo;

public SiteController(IDashboardRepository repo)
{
    _repo = repo;
}

库:

DashboardDbContext _context;

public DashboardRepository(DashboardDbContext context)
{
    _context = context;
}

UnityResolver 码:

public class UnityResolver : IDependencyResolver
{
    private readonly IUnityContainer _container;

    public UnityResolver(IUnityContainer container)
    {
        _container = container;
    }

    public object GetService(Type serviceType)
    { …
