我使用后送文件上传控制器我CustomerPortal建立与MVC4。
内CustomerPortal可以添加SupportCalls。内支援呼叫您可以附加文件。每一个的SupportCall都有自己的GUID。

I'm using Backload file upload controller in my CustomerPortal build with MVC4. Within the CustomerPortal you can add SupportCalls. Within the SupportCall you can attach files. Every SupportCall has its own Guid.

该web.backload.default.config文件包含文件〜/ Files下的默认上传位置。
不过，我要的文件位置是为每一个不同的SupportCall。爱：〜/文件/ d764578d-2f13-4820-bf1f-3d4427aedf22里的GUID不同，每次

The web.backload.default.config file contains the default upload location of the file "~/Files". However I want the file location to be different for every SupportCall. Like: "~/Files/d764578d-2f13-4820-bf1f-3d4427aedf22" where the Guid differs every time.

我怎样才能做到这一点？

I found the answer to my question here : https://github.com/blackcity/Backload/wiki/Example-06

<form id="fileupload" 
      action="/Backload/UploadHandler" 
      method="POST" 
      enctype="multipart/form-data">

    <input type="hidden" 
           name="objectContext" 
           value="@Html.ViewBag.Id" />

只是必须添加一个隐藏字段具有ID
