如何在Razor页中使用模型绑定验证来验证日期是否为过去日期

public class MyModel
{
    [Required(ErrorMessage = "日期不能为空")]
    [Display(Name = "日期")]
    [DataType(DataType.Date)]
    [PastDate(ErrorMessage = "日期必须是过去的日期")]
    public DateTime Date { get; set; }
}

@model MyModel

@using (Html.BeginForm())
{
    @Html.ValidationSummary()

    <div class="form-group">
        @Html.LabelFor(m => m.Date)
        @Html.TextBoxFor(m => m.Date, new { @class = "form-control" })
        @Html.ValidationMessageFor(m => m.Date)
    </div>

    <button type="submit" class="btn btn-primary">提交</button>
}

public class PastDateAttribute : ValidationAttribute
{
    public override bool IsValid(object value)
    {
        if (value is DateTime date)
        {
            return date.Date < DateTime.Now.Date;
        }
        return false;
    }
}

[HttpPost]
public ActionResult MyAction(MyModel model)
{
    if (ModelState.IsValid)
    {
        // 模型验证通过，执行相应的操作
        // ...
        return RedirectToAction("Success");
    }

    // 模型验证失败，返回表单页面并显示错误信息
    return View(model);
}
