如何使用plupload和asp.net mvc 3上传文件？

Question

我想知道如何上传文件与asp.net mvc 3和plupload插件

我试过HttpPostedFileBase，但它似乎总是空;

我发现这个page但如果是asp.net的MVC 3

新的方式，我也不能100％确定是什么在这是怎么回事，我不知道。它实际上是否将文件保存到服务器（App_data），因为我不想要这个。我试图上传icals，然后从icals中提取这些值并将它们导入到db中。

然后摆脱文件。所以我宁愿不保存到服务器，如果有必要。

Answer 1

确保您的表单包含enctype = "multipart/form-data"

@using (Html.BeginForm("upload", "home", FormMethod.Post, 
    new { enctype = "multipart/form-data" })) 

，让您的输入名称

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

控制器上

public ActionResult Upload(HttpPostedFileBase file) 

Answer 2

看看这里的一样：

$("#uploader").pluploadQueue({ 
     // General settings 
     runtimes: 'silverlight', 
     url: '/Home/Upload', 
     max_file_size: '10mb', 
     chunk_size: '1mb', 
     unique_names: true, 
     multiple_queues: false, 

     // Resize images on clientside if we can 
     resize: { width: 320, height: 240, quality: 90 }, 

     // Specify what files to browse for 
     filters: [ 
      { title: "Image files", extensions: "jpg,gif,png" }, 
      { title: "Zip files", extensions: "zip" } 
     ], 

     // Silverlight settings 
     silverlight_xap_url: '../../../Scripts/upload/plupload.silverlight.xap' 
     }); 

     // Client side form validation 
     $('form').submit(function (e) { 
     var uploader = $('#uploader').pluploadQueue(); 

     // Files in queue upload them first 
     if (uploader.files.length > 0) { 
      // When all files are uploaded submit form 
      uploader.bind('StateChanged', function() { 
       if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) { 
        $('form')[0].submit(); 
       } 
      }); 

      uploader.start(); 
     } else { 
      alert('You must queue at least one file.'); 
     } 

     return false; 
     }); 

并在控制器：

[HttpPost] 
public string Upload() { 
      HttpPostedFileBase FileData = Request.Files[0]; 

      if (FileData.ContentLength > 0) { 
      var fileName = Path.GetFileName(FileData.FileName); 
      var path = Path.Combine(Server.MapPath("~/Content"), fileName); 
      FileData.SaveAs(path); 
      } 

      return "Files was uploaded successfully!"; 
     } 

这一切......需要在控制器中没有大块......
