There isn't an html helper for file inputs, but what is wrong with just doing
没有用于文件输入的 html 帮助程序，但是这样做有什么问题
@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new {enctype = "multipart/form-data"})) {
<input type='file' name='blah' id='blah' />
}

There is a FileUpload class in Microsoft.Web.Helpers... http://msdn.microsoft.com/en-us/library/microsoft.web.helpers.fileupload(v=vs.99).aspx
Microsoft.Web.Helpers 中有一个 FileUpload 类... http://msdn.microsoft.com/en-us/library/microsoft.web.helpers.fileupload(v=vs.99).aspx
The best/only way I've found to get it is by using NuGet in VisualStudio. Search for package "microsoft-web-helpers" in the online repository. There is one problem I encountered, however. One of the package's dependencies is Facebook.Helper, which it will install at the same time. It will place a file called "Facebook???.cshtml" (forgot the exact name) in your project's AppCode directory. The problem is that the Facebook???.cshtml had some WebMatrix dependencies that I didn't have and didn't want to install. Simply deleting the Facebook.cshtml file (which I wasn't going to use, anyway) seemed to resolve the issue. After that, I was able to compile and debug as usual and use the FileUpload class.
我发现获得它的最佳/唯一方法是在 VisualStudio 中使用 NuGet。在在线存储库中搜索包“microsoft-web-helpers”。但是，我遇到了一个问题。该包的依赖项之一是 Facebook.Helper，它将同时安装。它将在您项目的 AppCode 目录中放置一个名为“Facebook???.cshtml”（忘记确切名称）的文件。问题是 Facebook???.cshtml 有一些我没有也不想安装的 WebMatrix 依赖项。简单地删除 Facebook.cshtml 文件（无论如何我不会使用它）似乎可以解决问题。之后，我可以像往常一样编译和调试并使用 FileUpload 类。
Here's a tutorial I found that utilizes it:
