在mvc中 怎么给@Html.HiddenFor()赋值

@Html.HiddenFor(model => model.CreatedBy, new { @value=currentInfo.UserID})  value始终是null
@Html.TextBoxFor(model => model.CreatedBy, new { @value=currentInfo.UserID}) 
这样子value就会有值

---

把value 的V改大写 就可以了
@Html.HiddenFor(model => model.RenyuanID, new { @Value = @ViewData["renyuanID"] }

---

For
ViewData

public class MyViewModel
{
 [HiddenInput(DisplayValue = false)]
 public string CRN { get; set; }
}

有我的控制器动作填充此视图模型：

public ActionResult Index()
{
 var model = new MyViewModel
 {
  CRN = "foo bar"
 };
 return View(model);
}

再有我强类型视图EditorFor助手：

@model MyViewModel
@Html.EditorFor(x => x.CRN)

这将

<input id="CRN" name="CRN" type="hidden" value="foo bar" />

Html.Hidden
Html.HiddenFor

@Html.Hidden("CRN", ViewData["crn"]);

INPUT
type="hidden"
id="CRN"
name="CRN"
value

@Html.HiddenFor(x => x.CRN, new { @Value = "1" });

你需要在@价值一资'V' 这里是我的模型

public int CRN { get; set; }

这里是输出的是当你看到在浏览器

<input value="1" data-val="true" data-val-number="The field CRN must be a number." data-val-required="The CRN field is required." id="CRN" name="CRN" type="hidden" value="1"/>

这里是

[HttpPost]
public ActionResult MyMethod(MyViewModel viewModel)
{
 int crn = viewModel.CRN;
}
