我在带有一些字符串字段和图像的模型上有一个 Post 控制器。完全相同的代码适用于 MVC4,但在 MVC 5 中 Request.Files.Count 始终为 0
我的模型有 byte[] 用于图像而不是 HttpPostedFileBase
我的观点:
@using (Html.BeginForm("Create", "HotelManager", FormMethod.Post, new { enctype = "multipart/form-data", data_ajax = "false" }))
{
@Html.AntiForgeryToken()
@Html.TextBoxFor(model => model.Title, new { @class = "form-control" })
@Html.TextAreaFor(model => model.Description, new { @class = "form-control", @rows = "7" })
<input type="file" class="form-control filestyle">
<input type="submit" value="Submit" class="btn btn-block" />
}
我试过省略 data_ajax = "false" 但没有用。
我的帖子控制器如下:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "Title,Description,Image")] Hotel hotel)
{
if (ModelState.IsValid)
{
// deal with the uploaded file
if (Request.Files.Count > 0)
{
HttpPostedFileBase file = Request.Files[0];
if (file != null && file.ContentLength > 0)
{
// Code to process image, resize, etc goes here
}
}
// Other code to add the hotel to db goes here
}
在调试器中,我看到 Request.Files.Count 始终为零,我不知道为什么?我已经从另一个 MVC4 项目中复制了视图和控制器代码,它工作正常。
