回发时，模型包含空字段 [英] Model contains null fields when posting back

问题描述

我有一个问题，我上回发的模式。该模型的字段都为空。我缺少什么？

I have a problem with my model on a postback. The fields of the model are all null. What am I missing?

下面是我的模型：

public class NewDiscussionModel
    {
        [DataType(DataType.Text)]
        [Required]
        [Display(Name="Title")]
        public string Title;

        [DataType(DataType.MultilineText)]
        [Required]
        [Display(Name="Message")]
        public string Message;
    }

下面是我的控制器：

[HttpPost]
[Authorize]
public ActionResult NewDiscussion(NewDiscussionModel model)
{
    return View();
}

下面是我的看法：

@model Tarantula.Models.NewDiscussionModel

@{
    ViewBag.Title = "Index";
}


<link rel="stylesheet" href="/codemiror/lib/codemirror.css".>
<script src="/codemirror/lib/codemirror.js"></script>
<script src="/codemirror/mode/javascript/javascript.js"></script>

@using (Html.BeginForm())
{
    @Html.LabelFor(m => m.Title)
    @Html.EditorFor(m => m.Title);
    @Html.LabelFor(m => m.Message);
    @Html.TextAreaFor(m => m.Message);
    <input type="submit" value="Submit" />
}

任何帮助非常AP preciated。

Any help greatly appreciated.

推荐答案

您错过getter和setter

you're missing getters and setters

public class NewDiscussionModel
    {
        [DataType(DataType.Text)]
        [Required]
        [Display(Name="Title")]
        public string Title {get; set;}

        [DataType(DataType.MultilineText)]
        [Required]
        [Display(Name="Message")]
        public string Message{get; set;}
    }
