我有一个简单的问题。为什么在下面的代码中,这部分 - HttpPostedFileBase file
- 为空?当然ArticleModel model
不是空的,只是file
.
开始我的控制器操作:
public ActionResult Add(ArticleModel model, HttpPostedFileBase file)
...
我的表格:
<section id="">
@using (Html.BeginForm()) {
@Html.AntiForgeryToken()
@Html.ValidationSummary()
@ViewBag.Status
<fieldset>
<legend>Add</legend>
<ol>
<li>
@Html.LabelFor(m => m.title)
@Html.TextBoxFor(m => m.title)
</li>
<li>
@Html.LabelFor(m => m.Categories)
@Html.DropDownListFor(m=> m.categoryID, Model.Categories, "- lorem -", new { @class="dropdownlist" })
</li>
<li>
@Html.LabelFor(m => m.connectedArticlesID)
@Html.TextBoxFor(m => m.connectedArticlesID)
</li>
<li>
<input type="file" name="file" id="file" />
</li>
<li>
@Html.LabelFor(m => m.introduction)
@Html.EditorFor(m => m.introduction)
</li>
<li>
@Html.LabelFor(m => m.content)
@Html.EditorFor(m => m.content)
</li>
</ol>
<input type="submit" value="Add" />
</fieldset>
}
</section>
编辑:
我的模型
