好吧，我已经在这个持续了几个小时，我根本无法找到解决方案。

Ok, I've been going at this for several hours and I simply cannot find the solution.

我想从我的用户获取一些数据。因此，首先，我用一个控制器来创建一个接收模型的视图：

I want to get some data from my user. So first, I use a controller to create a view which receives a Model:

public ViewResult CreateArticle() { Article newArticle = new Article(); ImagesUploadModel dataFromUser = new ImagesUploadModel(newArticle); return View(dataFromUser); }

然后，我的观点：

Then, I have the view:

<asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlaceHolder" runat="server"> <h2>AddArticle</h2> <% using (Html.BeginForm("CreateArticle", "Admin", FormMethod.Post, new { enctype = "multipart/form-data" })){ %> <%= Html.LabelFor(model => model.newArticle.Title)%> <%= Html.TextBoxFor(model => model.newArticle.Title)%> <%= Html.LabelFor(model => model.newArticle.ContentText)%> <%= Html.TextBoxFor(model => model.newArticle.ContentText)%> <%= Html.LabelFor(model => model.newArticle.CategoryID)%> <%= Html.TextBoxFor(model => model.newArticle.CategoryID)%> <p> Image1: <input type="file" name="file1" id="file1" /> </p> <p> Image2: <input type="file" name="file2" id="file2" /> </p> <div> <button type="submit" />Create </div> <%} %> </asp:Content>

和最后 - 原始控制器，但这次配置为接受数据

and finally - the original controller, but this time configured to accept the data:

[HttpPost] public ActionResult CreateArticle(ImagesUploadModel dataFromUser) { if (ModelState.IsValid) { HttpPostedFileBase[] imagesArr; imagesArr = new HttpPostedFileBase[2]; int i = 0; foreach (string f in Request.Files) { HttpPostedFileBase file = Request.Files[f]; if (file.ContentLength > 0) imagesArr[i] = file; }

该控制器的其余部分，因为没有不管我做什么，在计数属性 Request.Files （或 Request.Files.Keys ）保持为0。我根本无法找到一个方法来从表单传递文件（模型通过就好了）。

The rest of this controller does not matter since no matter what I do, the count attribute of Request.Files (or Request.Files.Keys) remains 0. I simply can't find a way to pass the files from the form (the Model passes just fine).

推荐答案

您可能要考虑不与形式 - 其余张贴文件有good原因等方式你可以达到你想要的东西。

You might want to consider not posting the files with the rest of the form- there are good reasons and other ways you can achieve what you want.
