Question

我需要验证日期时间对验证是否有效。

Razor MVC3

类

[Range(typeof(DateTime), "1/1/1930", "1/1/2112", 
 ErrorMessage = "Value for {0} must be between {1} and {2}")]
public DateTime DOB { get; set; }

修改查看表单

<span class="editor-field">
@Html.EditorFor(model => model.DOB)
@Html.ValidationMessageFor(model => model.DOB)

验证会捕获无效日期，但在输入有效日期时不会清除错误，因此表单已挂起。有没有人知道使用验证来检查日期时间是否有效的工作方式？

谢谢，乔

更新了控制器操作

[HttpPost]
public ActionResult Create(Talent talent)
{
  talent.Modified = talent.Created = DateTime.Now;
  if (talent.DOB < DateTime.Now.AddYears(-100) || talent.DOB > DateTime.Now)
  {
    talent.DOB = DateTime.Parse("0001/01/01"); talent.Skill = "changed"; 
    return View(talent); }

最终控制者和后期行动

string errorMessageDOB = "DOB is out of range, it needs to be between " + DateTime.Now.AddYears(-100).ToShortDateString()
    + " and " + DateTime.Now.ToShortDateString() + ".";
//
// POST: /Talent/Create

[HttpPost]
public ActionResult Create(Talent talent)
{
  talent.Modified = talent.Created = DateTime.Now;
  if (talent.DOB < DateTime.Now.AddYears(-100) || talent.DOB > DateTime.Now)
  { ModelState.AddModelError(string.Empty, errorMessageDOB); }
