使用ASP.NET MVC上传多个文件/文件路径

我正在为房地产经纪公司创建一个Web应用程序，并且在用于上载房地产的一种表格上，我需要将多个图像或pdf格式的平面图之类的文件上载到一个文件夹，并将其路径存储在数据库中(SQL SERVER).

I am creating a web application for an estate agency and on one of the forms used to upload properties i need to upload multiple images or files like floorplans in pdf format to a folder and store their path in the database(SQL SERVER).

我尝试使用在线资源中的一些帮助独自完成此操作，但无法对其进行整理.

I have tried doing it on my own using some help from online resources but have not been able to sort it out.

这是我上传文件视图的一部分.

This is the part of my view with the file upload.

<div class="file_inputs">

<input type="file" id="dev_brochure" name="dev_brochure" class="form-control adminarea_files">
<input type="file" id="devListingImg1" name="devListingImg1" class="form-control adminarea_files">
<input type="file" id="devListingImg2" name="devListingImg2" class="form-control adminarea_files">
<input type="file" id="devListingImg3" name="devListingImg3" class="form-control adminarea_files"> 

</div>

这是我的控制器，负责处理文件上传

This is my controller that processes the file upload

[HttpPost]
public ActionResult InsertDevelopment(development dev, IEnumerable <HttpPostedFileBase> files) 
    {
        try 
        {
          var supportedFileTypes = new [] {"jpg", "jpeg", "png", "gif", "pdf"};
            foreach(var file in files)
            {
              if(file.ContentLength > 0)
              {
                var fileExt = Path.GetExtension(file.FileName).Substring(1);
       if(!supportedFileTypes.Contains(fileExt))
           {
       TempData["Msg"] = "You have tried to upload a file type that is not allowed";
 return RedirectToAction("Create");
                    }

                 }
                }

            var devBrochure = Path.GetFileName(Request.Files["dev_brochure"].FileName);
           var devListingPhoto1_LinkName = Path.GetFileName(Request.Files["devListingImg1"].FileName);
           var devListingPhoto2_LinkName = Path.GetFileName(Request.Files["devListingImg2"].FileName);
           var devListingPhoto3_LinkName = Path.GetFileName(Request.Files["devListingImg3"].FileName);

           return View("Create");
        }
        catch(Exception e)
        {
            TempData["Msg"] = "Development upload failed :" + e.Message;
            return View("Create");
        }


    }

我的主要问题是在控制器操作的 IEnumerable< HttpPostedFileBase>中未接收到视图中的文件.文件参数.

My main problem here is that the files from the view are not being received in the controller action's IEnumerable <HttpPostedFileBase> files parameter.

我希望通过任何形式的指南来解决此问题.谢谢

I would appreciate any form of guide to fix this. Thanks
