在服务器站点上传多个文件/访问输入ID

我想上传几个文件。上传本身适用于单个上传，但我无法弄清楚如何访问元素名称以确保每次上传都分配到了正确的字段。 HttpPostedFileBase似乎不再包含该类型的信息。在服务器站点上传多个文件/访问输入ID

public ActionResult Edit(int id, FormCollection collection) { 
    Report report = re.GetReport(id); 
    var fileNames = new List<string>(); 

    foreach (string file in Request.Files) { 
     var postedFile = Request.Files[file] as HttpPostedFileBase; 
     if (postedFile.ContentLength == 0) 
      continue; 
     fileNames.Add(UploadFile(basedir, postedFile)); 
    } 

    // Rather than guessing which is which I'd like to get the field name or id. 
    report.Image = fileNames[0]; 
    report.File = fileNames[1]; 

    UpdateModel(report, "report"); 
    rep.Save();

在视图中我有

<%: Html.LabelFor(model => model.report.Image)%> 
<input id="report_Image" type="file" name="Image" /> 

<%: Html.LabelFor(model => model.report.File)%> 
<input id="report_Image" type="file" name="File" />

感谢，达菲

var fileNames = new List<string>(); 

     foreach (string file in Request.Files) { 
      var postedFile = Request.Files[file] as HttpPostedFileBase; 
      if (postedFile.ContentLength == 0) 
       continue; 
      fileNames.Add(UploadFile(basedir,postedFile)); 
     }

在foreach变量文件包含了您输入字段的名称。所以它的价值将分别是图像和文件。我检查在MVC2

所以，你可以像这样

var fileNames = new Dictionary<string,string>(); 

       foreach (string file in Request.Files) 
       { 
        var postedFile = Request.Files[file] as HttpPostedFileBase; 
        if (postedFile.ContentLength == 0) 
         continue; 
        fileNames.Add(file,UploadFile(basedir,postedFile)); 
       } 

       //Now you have added the values with key so you can use the 
       //input field name to access them 
       report.Image = fileNames["Image"]; 
       report.File = fileNames["File"];
