Question

我正在.net核心Web API环境中的成员资格模块上工作。我需要公开用于更新成员资格的Update方法。到目前为止，这是我的实现；

//Entity
public class Membership
{
    public int Id { get; set; }
    public int UserId { get; set; }
    public MembershipType MembershipType { get; set; }
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
    public bool AutoRepeat { get; set; }
    public virtual User User { get; set; }
}

public enum MembershipType
{
    Standard = 1,
    Premium,
    Ultimate
}

我的控制器方法希望该模型更新相关实体

public class MembershipUpdateModel
{
    public int Id { get; set; }
    public MembershipType MembershipType { get; set; }
    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
    public bool AutoRepeat { get; set; }
}

此类包含我的业务逻辑，例如验证等。

public class MembershipManager
{
    //This instance handles db related works.
    IMembershipService membershipService;
    public MembershipManager(IMembershipService membershipService)
    {
        this.membershipService = membershipService;
    }
    public bool UpdateMembership(MembershipUpdateModel updateModel)
    {
        if (updateModel is null)
            return false;
        //Below I need to control the dates if they are changed
        if (false == ValidateUpdateModelDates(updateModel.StartDate, updateModel.EndDate))
            return false;
        return membershipService.UpdateMembership(updateModel);
    }

    public bool ValidateUpdateModelDates(DateTime stara tDate, DateTime endDate)
    {
        var now = DateTime.Now;
        if (startDate >= endDate)
            return false;
        if (startDate <= now)
            return false;
        return true;
    }
}

我的问题：当客户端在startDate值之后发送旧日期而没有任何更改时，我的ValidateUpdateModelDates方法r变为false。客户端只能发送没有日期的更改值，但更新模型会反序列化为DateTime.MinValue和ValidateUpdateModelDates再次返回false。我可以打数据库检查StartDate是否更改。但是我不确定这是否是解决这种情况的最佳方法。有什么方法可以知道客户端在反序列化数据时是否更改了数据？

谢谢。
