我尝试将使用文件上传控件上传的viewmodel和多个文件传递给控制器。无论files参数传递为null。
如何将上传的文件传递给控制器。
这是我的观点
@model DMS.BO.ViewModels.UploadDocumentViewModel
<div class="content-wrapper">
<form id="frmAddService" action="@Url.Action("UploadDocuments", "Home")" method="post" enctype="multipart/form-data">

我的控制器
[HttpPost]
public ActionResult UploadDocuments(UploadDocumentViewModel uploadvm, IEnumerable<HttpPostedFileBase> files)
{
HostBL hostbl = new HostBL();
DocumentBL documentbl = new DocumentBL();
//CompanyBL companybl=new CompanyBL();
long hostid = hostbl.CheckIfHostExists(uploadvm.hostbo.HostIp, uploadvm.hostbo.CompanyId);
if (hostid == 0 || hostid == null)
hostid = hostbl.InsertHost(uploadvm);
uploadvm.hostbo.HostId = hostid;
long serviceprocedureid = hostbl.InsertDetails(uploadvm);
//var CompanyName = companybl.getCompanyName(uploadvm.companybo.CompanyId);
List<ProcedureDocumentBO> documents = new List<ProcedureDocumentBO>();
//iterating through multiple file collection
foreach (HttpPostedFileBase file in files)
{
//Checking file is available to save.
if (file != null)
{
ProcedureDocumentBO proceduredocumentbo = new ProcedureDocumentBO();
var InputFileName = Path.GetFileName(file.FileName);
var filename = uploadvm.companybo.CompanyName
+ "_" + uploadvm.hostbo.HostName
+ "_" + uploadvm.servicebo.ServiceName
+ "_" + DateTime.Now.ToString("yyyyMMddHHmmssfff")
+ "_" + InputFileName;
proceduredocumentbo.DocumentFileName = filename;
proceduredocumentbo.ServiceProcedureId = serviceprocedureid;
proceduredocumentbo.CreatedOn = System.DateTime.Today;
var ServerSavePath = Path.Combine(Server.MapPath("~/UploadedFiles/") + filename);
//Save file to server folder
file.SaveAs(ServerSavePath);
//assigning file uploaded status to ViewBag for showing message to user.
//ViewBag.UploadStatus = uploadvm.files.Count().ToString() + " files uploaded successfully.";
documents.Add(proceduredocumentbo);
//long documentid=documentbl.InsertDocument(uploadvm.documentbo);
}
}
uploadvm.documents = documents;
int res = documentbl.InsertDocuments(uploadvm);
//uploadvm.documents=
if (res <= 0)
{
TempData["Message"] = "Documents Not Uploaded";
}
else
{
TempData["Message"] = "Documents Uploaded";
}
UploadDocumentViewModel uploadvmm = new UploadDocumentViewModel();
CompanyBL companybl = new CompanyBL();
ServiceBL servicebl = new ServiceBL();
uploadvmm.companies = companybl.GetAllCompanies();
uploadvmm.services = servicebl.GetAllServices();
return View(uploadvmm);
}
传递的files参数对我来说始终为null。如何传递文件？
答案 0 :(得分：0)
public string writeFile(HttpPostedFileBase file, string fileName, string folder, HttpServerUtilityBase Server)
{
string FileName = fileName;
if (file != null && file.ContentLength > 0)
{
FileName = string.Format("{0}" + file.FileName.Trim('"'), DateTime.Now.Ticks);
string nameAndLocation = "~/" + folder + "/" + FileName;
file.SaveAs(Server.MapPath(nameAndLocation));
}
return FileName;
}
[HttpPost]
public string upload(Tunes tune)
{
var img = Request.Files["ImgFile"];
var mp3 = Request.Files["Mp3File"];
var image = writeFile(img, "", "TuneImages", Server);
var mp3Name = writeFile(mp3, "", "mp3", Server);
tune.mp3 = mp3Name;
tune.img = image;
db.Tunes.Add(tune);
db.SaveChanges();
return "Record Save Successfully";
}
您可以循环Request.Files，您可以轻松上传多个文件而无需绑定视图模型。 Request.Files["ImgFile"] Request.Files["Mp3File"]
ImgFile和Mp3File名称
