Question

我有这个简单的添加到db方法，我不断收到此错误

将datetime2数据类型转换为日期时间数据类型会导致超出范围的值。声明已经终止＆＃34;

在调试器中，我看到呈现的日期是＆＃34; 01/01/0001 00：00：00＆＃34;。我几乎可以肯定这不是今天，因为我通过DateTime.Now设置了它。

public class UDetails
{
    [Key]
    public string UDetailsId { get; set; }
    [Display(Name = "Your name")]
    public string UName { get; set; }
    public string Email { get; set; }
    [Display(Name = "Date of birth")]
    public DateTime? DOB { get; set; }
    [Display(Name = "my DOB is publich")]
    public bool IsPublic { get; set; }

    public string Gender  { get; set; }
    public DateTime? RegesterDate { get; set; }

    [Display(Name = "Occupation")]
    public string OccupationDecription { get; set; }

    public string UserPhoto { get; set; }
    public int OccupationId { get; set; }
}

var entity = new UDetails()
{
    UserPhoto = model.UserPhoto,
    DOB = model.DOB,
    IsPublic = model.IsPublic,
    Gender = model.Gender,
    OccupationDecription = model.OccupationDecription
};
model.Email = User.Identity.Name;
model.RegesterDate = DateTime.Now;
model.UDetailsId = User.Identity.GetUserId();

db.udetails.Add(entity);
db.SaveChanges();
return View("index");

您正在将RegesterDate添加到模型中（可能是您的参数）。这应该解决：

var entity = new UDetails()
{
    // ...

    Email = User.Identity.Name,
    RegesterDate = DateTime.Now,
    UDetailsId = User.Identity.GetUserId()      

    // ...
};

DateTime属性保留在01/01/0001
