C# Razor视图文本框问题

如何让DateCreated字段自动填充DateTime。现在

   <div class="editor-label">
        @Html.LabelFor(model => model.DateCreated)
   </div>
   <div class="editor-field">
        @Html.EditorFor(model => model.DateCreated)
        @Html.ValidationMessageFor(model => model.DateCreated)
   </div>

@LabelFor（model=>model.DateCreated）
@EditorFor（model=>model.DateCreated）
@Html.ValidationMessageFor（model=>model.DateCreated）

这通常是您在视图范围之外（即在控制器中）执行的操作

public ActionResult MyAction()
{
    var model = new MyModel();
    model.DateCreated = model.DateCreated ?? DateTime.Now;
    return View(model);
}

或者，在模型本身的构造函数中
