型号为“int”时，在Web上输入框作为“日期”（再次）

Question

我决定在这里创建一个新帖子，而不是另一个有点令人困惑的帖子。（Input box as "date" on web when model is "int"）

在这篇文章中，我添加了我使用的代码。

问题是在SQL服务器中，字段FrDr的类型为int，我需要网页上的用户输入“date”类型的输入字段

如果我将[DataType（DataType.Date）]添加到模型中，我会自动获得输入日期类型。但如果我将它添加到Page Model中则不行

如何更改我的代码，以便用户获得类型为date的输入字段，将日期值保存为int到SQL。

MODEL AGR.CS

namespace DateTest.VismaModels {

    public partial class Agr {


        [Key]
        [Display(Name = "Actor")]
        public int AgrActNo { get; set; }

        public int AgrNo { get; set; }

        [DataType(DataType.Date)]
        [Display(Name = "From Date")]
        public int FrDt { get; set; }

    }
}

PAGE MODEL

   namespace DateTest.Pages {

    public class IndexModel : PageModel {
        private readonly DateTest.VismaModels.F0001Context _context;


        public IndexModel(DateTest.VismaModels.F0001Context context) {
            _context = context;
        }

        public bool ShowMessage => !string.IsNullOrEmpty(Message);

        [TempData]
        public string Message { get; set; }

        [BindProperty]
        public Agr AgrRow { get; set; }

        public async Task<IActionResult> OnGetAsync(int? id) {


            if (id == null) {
                Console.WriteLine("New");
                AgrRow = new Agr();
                AgrRow.AgrNo = _context.Agr.Select(q => q.AgrNo).DefaultIfEmpty(0).Max() + 1;
                //AgrRow.FrDt = int.Parse(DateTime.Now.ToString("yyyyMMdd"));

            }
            if (!ModelState.IsValid) {
                //var errors = ModelState.Select(x => x.Value.Errors).Where(y => y.Count > 0).ToList();
                var errors = string.Join(" | ", ModelState.Values.SelectMany(v => v.Errors).Select(e => e.ErrorMessage));
                Message += "Model not valid : " + errors;
                return Redirect("~/Activities/index");
            }
            return Page();
        }



        public async Task<IActionResult> OnPostSaveNewRowAsync() {


            if (!ModelState.IsValid) {
                //var errors = ModelState.Select(x => x.Value.Errors).Where(y => y.Count > 0).ToList();
                var errors = string.Join(" | ", ModelState.Values.SelectMany(v => v.Errors).Select(e => e.ErrorMessage));
                Message += "Model not valid : " + errors;
                return Redirect("~/index");
            }


            _context.Add(AgrRow);

            try {
                await _context.SaveChangesAsync();
            } catch (DbUpdateConcurrencyException) {
                throw;

            }
            Message += "Saved";
            return RedirectToPage("/index");
        }


    }



}

UPDATE

如果我将以下内容添加到页面模型中

public DateTime FrDt { get; set; }

并在这样的post方法中打印出结果

Console.WriteLine("FRDT = " + FrDt);
Console.WriteLine("AGRROW FRDT = " + AgrRow.FrDt);

我明白了

FRDT = 0001-01-01 00:00:00
AGRROW FRDT = 0
