抱歉，如果這個問題已經有答案，但我找不到。提交表單時，我的ViewModel會丟失一些值。具體來說，錯誤對象會丟失其值。我不明白為什么。我沒有任何東西可以覆蓋它。我非常感謝我能得到的任何幫助。我嘗試刪除= new ...()，但這會使程序拋出錯誤不是對象的實例視圖模型：namespace Vacation.ViewModels{    public class EditScheduleViewModel : BaseViewModel    {        public EditScheduleError Error { get; set; } = new EditScheduleError();        public string GotoSched { get; set; } = "";        public string GotoURL { get; set; } = "";        public string Title { get; set; } = "";        public bool isLast { get; set; } = false;        public User Employee { get; set; } = new User();        public int TotalWeeks { get; set; } = 2;        public Schedule ScheduleActive { get; set; } = new Schedule();        public DateTime LastSchedEndDate { get; set; }        public List<Schedule> ScheduleAll { get; set; } = new List<Schedule>();        public List<ScheduleDay> Days { get; set; } = new List<ScheduleDay>(new ScheduleDay[28]);        public List<int> ClinicIds { get; set; } = new List<int>(new int[28]);        public List<ClinicInfo> ClinicsList { get; set; } = new List<ClinicInfo>();        public EditScheduleViewModel ()        {            ProjectName = "Scheman";        }    }    public class EditScheduleError    {        public bool Overlaps { get; set; }        public EditScheduleOverlappingError OverlappingError { get; set; } = new EditScheduleOverlappingError();    }    public class EditScheduleOverlappingError    {        public bool OverlapsBefore { get; set; }        public bool OverlapsAfter { get; set; }        public int IdBefore { get; set; }        public int IdAfter { get; set; }        public EditScheduleOverlappingErrorResolutions Resolution { get; set; } = new EditScheduleOverlappingErrorResolutions();    }    public class EditScheduleOverlappingErrorResolutions    {        public bool ChangeThis { get; set; }        public bool ChangeOther { get; set; }    }}這不是控制器的全部部分...您需要更多嗎？預期的行為是錯誤保持其值，即使在我提交了表單之后也是如此。
