mvc表单无法通过验证

[纯五度]

一个文章评论表单无法通过验证,表单是部分视图,名为Comment放在Shared,调用方法是:@Html.Action("Comment","Home")
其中:Models:

public class TableDiscuss
    {
        public int ID { get; set; }
        [Display(Name = "文章ID")]
        public int Topic { get; set; }
        [Display(Name = "评论内容")]
        [StringLength(255, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = 6)]
        [Required(ErrorMessage = "×")]
        [DataType(DataType.MultilineText)]
        public string Content { get; set; }
        [Display(Name = "评论时间")]
        [DataType(DataType.Date)]
    }

HomeController:

public ActionResult Comment(int id)
        {
            ViewBag.ID = id;
            return View();
        }

        [HttpPost]
        public ActionResult Comment(TableDiscuss tablediscuss, int id)
        {
            ViewBag.ID = id;
            if (ModelState.IsValid)
            {
                tablediscuss.IpTime = DateTime.Now;
                tablediscuss.Topic = id;
                db.tbDiscuss.Add(tablediscuss);
                db.SaveChanges();
                return RedirectToAction("Comment");
            }
            return View(tablediscuss);
        }

Comments.cshtml

@model Web.Models.TableDiscuss
@{
    Layout = null;
}
@using (Html.BeginForm())
        {
            @Html.ValidationSummary(true)
                <div class="editor-field">
                @Html.TextAreaFor(model=>model.Content, new { style = "width:95%;" })
                @Html.ValidationMessageFor(model => model.Content)
            </div>
                <div class="editor-field">
                <input type="submit" style="width:80px;" value="添写评论" />
            </div>
}

通不过验证,输入内容点击提交,直接跳过if (ModelState.IsValid).
不知为什么,高手帮忙给看看.

断点到if (ModelState.IsValid).这个地方,看一下各值情况.

谢谢,明白了,我在视图做了两个隐藏域,好了.
