ASP.NET-MVC5 5输入多个文件

Question

我正在使用ASP.NET MVC-5，我有一个按钮，允许我选择多个文件进行输入，所以它适用于以下代码

<input type="file" name="file" multiple>

如何从控制器获取文件，以便在HttpPost操作中的程序逻辑中使用它们？

Answer 1

在本例中，您可以从HttpPostedFileBase数组获得控制器操作中的上载文件。

        [HttpPost]
        public ActionResult Index(HttpPostedFileBase[] uploadedfiles)
        {
            try
            {
                // Loop through array fro getting files
                foreach (HttpPostedFileBase file in files)
                {
                    // get current file name
                    string filename = System.IO.Path.GetFileName(file.FileName);
                    //Saving the file in relative path (server folder)
                    file.SaveAs(Server.MapPath("~/Images/" + filename));
                    string filepathtosave = "Images/" + filename;

                    /* code for saving the image into database */

                }

                ViewBag.Message = "File Uploaded successfully.";
            }
            catch
            {
                ViewBag.Message = "Error while uploading the files.";
            }
            return View();
        }
