Asp.Net MVC Razor FileUpload Html Helper into existing View
提问by MaticDiba
I have have a View where I add products to a simple WebStore. I want to have multiple images with one product. That's why I use FileUpload from Microsoft.Web.Helpers. The use of FileUpload in my View is like this:
我有一个视图，可以将产品添加到一个简单的 WebStore。我想要一个产品有多个图像。这就是我使用 Microsoft.Web.Helpers 的 FileUpload 的原因。我的View中FileUpload的使用是这样的：
@FileUpload.GetHtml("Upload", 5, true, true, addText: "Add more", uploadText: "Upload files")
Then I have some labels and fields for other product attributs like this:
然后我有一些其他产品属性的标签和字段，如下所示：
<div class="editor-field"><br>
@Html.EditorFor(model => model.Title)<br>
@Html.ValidationMessageFor(model => model.Title)<br>
</div>
The problem is that when I use post method, my controller does not get anything. I use controller like this:
问题是当我使用 post 方法时，我的控制器没有得到任何东西。我使用这样的控制器：
[HttpPost]
public ActionResult Create(Product product, IEnumerable<HttpPostedFileBase> fileUpload)
{
foreach (var file in fileUpload)
{
var fileName = Path.GetFileName(file.FileName);
}
return RedirectToAction("Index");
}
So does anyone have any idea what I am doing wrong. Because my FileUpload object is always empty.
那么有没有人知道我做错了什么。因为我的 FileUpload 对象总是空的。

Most likely your BeginFormis missing the required field. It should look like this:
您很可能BeginForm缺少必填字段。它应该是这样的：
using(Html.BeginForm("Index", "Home", FormMethod.Post,
new { enctype="multipart/form-data" })) {
}
