File is not uploading in ASP.Net MVC - c#

Hi to all of you I am facing a problem on uploading a file and saving it into a folder here is my view
<div class="admin-empty-dashboard">
#using (Html.BeginForm("UploadResumes", "Employee", new { enctype = "multipart/form-data" }))
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<div class="icon">
<i class="ion-ios-book-outline"></i>
</div>
<h4>Welcome #Model.FullName!</h4>
<p>#ViewBag.Error</p>
<div class="form-group bootstrap-fileinput-style-01">
<label>Upload Resume</label>
<input type="file" name="file" required="required" class="btn btn-primary" style="margin-left:265px" accept="application/msword,text/plain, application/pdf">
<span class="font12 font-italic">** File must not bigger than 2MB</span>
</div>
<input type="submit" name="name" class="btn btn-primary" value="UploadResumes" />
}
</div>
and here is my controllers action problem is that it HttpPostedFileBase object value is always null and i ran Request.Files.Count it's also giving me zero where is problem?
public ActionResult UploadResumes(HttpPostedFileBase file)
{
if (Session["UserID"] != null && Session["UserName"] != null && Session["EmployeeID"] != null)
{
int id = Convert.ToInt32(Session["EmployeeID"]);
string[] allowedExtenssions = new string[] { ".pdf", ".doc", ".docx" };
string cvPath = "~/cvs/Employee_cvs/";
if (!Directory.Exists(Server.MapPath(cvPath)))
Directory.CreateDirectory(Server.MapPath(cvPath));
MyDbContext db=new MyDbContext();
tblEmployee employee = (from s in db.tblEmployees where s.UserId == id select s).FirstOrDefault();
// HttpPostedFileBase cv = Request.Files["CV"];
if (file != null)
{
if (file.ContentLength > 0)
{
string ext = Path.GetExtension(file.FileName);
if (allowedExtenssions.Contains(ext.ToLower()))
{
string fileName = DateTime.Now.Ticks + ext;
string filePath = cvPath + fileName;
string serverPath = Server.MapPath(filePath);
file.SaveAs(serverPath);
employee.cvUrl = filePath;
}
}
ViewBag.Error = "Some Error Occured";
}
return RedirectToAction("Dashboard");
}
else
{
return RedirectToAction("Login", "User");
}
}

Update like below and check
#using (Html.BeginForm("UploadResumes", "Employee",FormMethod.Post, new { enctype = "multipart/form-data" }))
{
}
Also
[HttpPost]
public ActionResult UploadResumes(HttpPostedFileBase file)
{
}

Try changing your parameters on your controller to
public ActionResult UploadResumes(Model yourModel, HttpHostedFileBase file)

In most of my controllers that require a file for upload, are usually array based. Make you function parameters an array like this:
public ActionResult UploadResumes(HttpPostedFileBase[] files){
}

access input value in webAPI from post

I use the following code to upload files using a webAPI, the file upload part works fine but how can I access all additional input values and hidden input values from the post?
[HttpPost]
public async Task<object> UploadFile()
{
if (!Request.Content.IsMimeMultipartContent("form-data"))
{
throw new HttpResponseException(Request.CreateResponse(HttpStatusCode.UnsupportedMediaType));
}
var streamProvider = new MultipartFormDataStreamProvider(HttpContext.Current.Server.MapPath("~/App_Data/Temp/"));
try
{
await Request.Content.ReadAsMultipartAsync(streamProvider);
foreach (MultipartFileData fileData in streamProvider.FileData)
{
var fileName = "";
if (string.IsNullOrEmpty(fileData.Headers.ContentDisposition.FileName))
{
fileName = Guid.NewGuid().ToString();
}
fileName = fileData.Headers.ContentDisposition.FileName;
if (fileName.StartsWith("\"") && fileName.EndsWith("\""))
{
fileName = fileName.Trim('"');
}
if (fileName.Contains(#"/") || fileName.Contains(#"\"))
{
fileName = Path.GetFileName(fileName);
}
File.Move(fileData.LocalFileName, Path.Combine(HttpContext.Current.Server.MapPath("~/App_Data/"), Path.GetDirectoryName(fileName) + Guid.NewGuid() + Path.GetExtension(fileName)));
}
return Request.CreateResponse(HttpStatusCode.OK);
}
catch (Exception e)
{
return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);
}
}
And here is the form I am using for posting the file.
<form name="form1" method="post" enctype="multipart/form-data" action="api/upload">
<div>
<label for="caption">Image Caption</label>
<input name="caption" type="text" />
</div>
<div>
<input type="hidden" value="secretvalue"/>
<label for="image1">Image File</label>
<input name="image1" type="file" />
</div>
<div>
<input type="submit" value="Submit" />
</div>

ASP.NET Razor File Upload

I'm following this example on the MS website for File Uploads using Razor and C#.
If I have more than one File upload buttons, how would the C# code know which button the uploaded file is from? Based on the button the file was uploaded from, I will be saving files to specific folders.
https://learn.microsoft.com/en-us/aspnet/web-pages/overview/data/working-with-files
#using Microsoft.Web.Helpers;
#{
var fileName = "";
if (IsPost) {
var fileSavePath = "";
var uploadedFile = Request.Files[0];
fileName = Path.GetFileName(uploadedFile.FileName);
fileSavePath = Server.MapPath("~/App_Data/UploadedFiles/" +
fileName);
uploadedFile.SaveAs(fileSavePath);
}
}
<!DOCTYPE html>
<html>
<head>
<title>FileUpload - Single-File Example</title>
</head>
<body>
<h1>FileUpload - Single-File Example</h1>
#FileUpload.GetHtml(
initialNumberOfFiles:1,
allowMoreFilesToBeAdded:false,
includeFormTag:true,
uploadText:"Upload")
#if (IsPost) {
<span>File uploaded!</span><br/>
}
</body>
</html>
The way to do this is to name the buttons the same, but give them different values. You can then do a case statement and direct the logic based on the value.
Razor
#using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<input type="file" name="FirstUpload" />
<input type="submit" name="submitID" id="submitID" value="Upload1" />
<input type="file" name="SecondUpload" />
<input type="submit" name="submitID" id="submitID" value="Upload2" />
}
Controller
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(FormCollection collection)
{
string btn = Request.Params["submitID"];
switch (btn)
{
case "Upload1":
for (int i = 0; i < Request.Files.Count; i++)
{
var file = Request.Files[i];
}
break;
case "Upload2":
for (int i = 0; i < Request.Files.Count; i++)
{
var file = Request.Files[i];
}
break;
}
return View();
}
I had a similar problem and ended up with following code:
Razor
//BeginForm and other staff
#foreach (var d in Model.Types)
{
<input type="file" name="doc:#d.Id:upload" />//#d.Id is the key point
<button formenctype="multipart/form-data"
type="submit" formaction="/MyController/uploaddoc"
name="typeid" formmethod="post" value="#d.Id">//this way I send Id to controller
Upload
</button>
}
MyController
[HttpPost]
[ValidateAntiForgeryToken]
[Route("mycontroller/uploaddoc")]//same as formaction
public async Task<ActionResult> UploadDoc(FormCollection data, int typeid)
{
//restore inpput name
var fl = Request.Files["doc:" + typeid.ToString() + ":upload"];
if (fl != null && fl.ContentLength > 0)
{
var path = Server.MapPath("~/app_data/docs");
var fn = Guid.NewGuid().ToString();//random name
using (FileStream fs = System.IO.File.Create(Path.Combine(path, fn)))
{
await fl.InputStream.CopyToAsync(fs);
}
}
}

MVC File is not being Posted back

HTTPPostedFileBase is always null in the controller. Please review and let me know where am I wrong.
Controller Post method
public ActionResult EditProfile(Contact model, HttpPostedFileBase picture, string currentPassword, string CurrentPasswordQ, string newPassword, string loginPwd, string currentPinQ, string newPin, int? selectedQuestion, string answer, bool pwdChange = false, bool questionChange = false, bool pinChange = false)
{
My Form Header
#using (Html.BeginForm("EditProfile", "CompanyAdmin", FormMethod.Post, new { enctype = "multipart/form-data", #data_ajax = "false" }))
{
And my file Input
<tr>
<td class="label_form_div">
<label>Profile Picture</label>
</td>
<td>
<input type="file" name="picture" />
</td>
</tr>
Please review and see if you can find what is wrong with this.
Thanks
Its seems your code is correct, anyway try this way in the controller. It might helpful for you:
public ActionResult EditProfile(Contact model, string currentPassword, string CurrentPasswordQ, string newPassword, string loginPwd, string currentPinQ, string newPin, int? selectedQuestion, string answer, bool pwdChange = false, bool questionChange = false, bool pinChange = false)
{
if (Request.Files != null && Request.Files.Count > 0)
{
HttpPostedFileBase file = Request.Files[0];
if (file != null && file.ContentLength > 0)
{
//other logic
}
}
}

Please follow the below steps.
Step :- 1
#using (Html.BeginForm("FileUpload", "Home", FormMethod.Post,
new { enctype = "multipart/form-data" }))
{
<label for="file">Upload Image:</label>
<input type="file" name="file" id="file" style="width: 100%;" />
<input type="submit" value="Upload" class="submit" />
}
Step :- 2
public ActionResult FileUpload(HttpPostedFileBase file)
{
if (file != null)
{
string pic = System.IO.Path.GetFileName(file.FileName);
string path = System.IO.Path.Combine(
Server.MapPath("~/images/profile"), pic);
// file is uploaded
file.SaveAs(path);
// save the image path path to the database or you can send image
// directly to database
// in-case if you want to store byte[] ie. for DB
using (MemoryStream ms = new MemoryStream())
{
file.InputStream.CopyTo(ms);
byte[] array = ms.GetBuffer();
}
}
// after successfully uploading redirect the user
return RedirectToAction("actionname", "controller name");
}

"Server Error in '/' Application" When uploading an image

I want to upload a profile picture to my system.But I click upload, "Server Error in '/' Application" message appears. Also I have figured out the URL is little bit different than Correct URL should be like this.
/ProfileController/UploadPhoto
But the URL in the here is /admin/ProfileController/UploadPhoto
What should do in order to make this work?
This is my code in controller
[HttpPost]
public ActionResult UploadPhoto(HttpPostedFileBase file)
{
if (file != null && file.ContentLength > 0)
{
var user = Session["userID"].ToString();
var fileExt = Path.GetExtension(file.FileName);
var fileName = user + ".png";
if (fileExt.ToLower().EndsWith(".png") || fileExt.ToLower().EndsWith(".jpg"))
{
var filePath = HostingEnvironment.MapPath("~/Content/images/profile/") + fileName;
var directory = new DirectoryInfo(HostingEnvironment.MapPath("~/Content/images/profile/"));
if (directory.Exists == false)
{
directory.Create();
}
ViewBag.FilePath = filePath.ToString();
file.SaveAs(filePath);
return RedirectToAction("Index", new { Message = ManageMessageId.PhotoUploadSuccess });
}
else
{
return RedirectToAction("Index", new { Message = ManageMessageId.FileExtensionError });
}
}
return RedirectToAction("Index", new { Message = ManageMessageId.Error });
}
This is the code in view
<dl class="dl-horizontal">
<dd>
#if (User != null)
{
var imgUrl = Url.Content("Content/Images/" + User + ".png") + "?time=" + DateTime.Now.ToString();
<div class="input-field col s12">
<div class="input-field col s12">
<img src="#imgUrl" height="250" width="250" />
</div>
<div class="mngimg">
#using (Html.BeginForm("UploadPhoto", "ProfileController", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<div class="input-field col s12">
<input type="file" name="file" id="files" onchange="this.form.submit()" />
</div>
}
</div>
</div>
}
</dd>
</dl>
RouteConfig.cs
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"AdminPanel",
"admin/{controller}/{action}/{id}",
new {`controller="Home", action = "Index", id = UrlParameter.Optional },
new[] { "OnlineElection.Controllers.Admin" } );
routes.MapRoute(
name:"Default",
url:"{controller}/{action}/{id}",
defaults:new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces:new[] { "OnlineElection.Controllers" }
);
The form URL you're posting to is invalid.
When using Controllers, you omit the Controller word and use only the name of the controller, in this case ProfileController becomes just Profile, this also counts for URL's.
Your Html.BeginForm should in fact be
#using (Html.BeginForm("UploadPhoto", "Profile", FormMethod.Post, new { enctype = "multipart/form-data" }))

Asp.NET MVC 4 Ajax Request Cancels on Submit

Issue Is with Ajax Request Cancel
After i call the ProcessMessage from form submit i am having issue
Issue with submitting your page is canceling my ajax request, so I am getting error..
Please help me on this
View
#using (Html.BeginForm("Index", "Home", FormMethod.Post, new { id = "formUpload", enctype = "multipart/form-data" }))
{
<div>
<b>Upload File</b>
<input type="file" name="file" />
<input type="submit" value="Upload File" name="btnUpload" onclick="progressStatus();"/><br />
</div>
<div>
#ViewBag.Message
</div>
<div style="width: 30%; margin: 0 auto;">
<div id="progressbar" style="width: 300px; height: 15px"></div>
<br/>
</div>
}
#Scripts.Render("~/bundles/jquery")
<script type="text/javascript">
function progressStatus() {
var oReq = new XMLHttpRequest();
oReq.open("get", "/Home/ProcessMessage", true);
oReq.send();
setInterval(showResult, 1000);
function showResult() {
var result = "";
if (result !== oReq.responseText) {
result = oReq.responseText;
debugger;
$("#progressbar").html(result);
}
}
return false;
}
</script>
Controller
[HttpPost]
public ActionResult Index(HttpPostedFileBase file)
{
if (file != null)
{
var fname = Path.GetFileName(file.FileName);
var exis = Path.Combine(System.Web.HttpContext.Current.Server.MapPath("~/Storage/uploads"), fname);
if (System.IO.File.Exists(exis))
{
ViewData["Message"] = "The file " + fname + " has already exists";
}
else
{
try
{
if (file.ContentLength > 0)
{
var fileName = Path.GetFileName(file.FileName);
var folderPath = Server.MapPath("~/Storage/uploads");
fname = fileName;
var path = Path.Combine(folderPath, fileName);
var filebytes = new byte[file.ContentLength];
if (!Directory.Exists(folderPath))
Directory.CreateDirectory(folderPath);
file.SaveAs(path);
}
ViewData["Message"] = "The file " + fname + " has uploaded successully";
}
catch (Exception e)
{
ViewData["Message"] = "The file " + fname + " Could not upload";
ViewData["Message"] = e.Message;
}
}
}
else
ViewData["Message"] = "Please choose file";
return View();
}
public class ProgressiveResult : ActionResult
{
public override void ExecuteResult(ControllerContext context)
{
for (int i = 0; i < 20; i++)
{
context.HttpContext.Response.Write(i.ToString());
Thread.Sleep(2000);
context.HttpContext.Response.Flush();
}
context.HttpContext.Response.End();
}
}
and this is an action that returns this result:
public ActionResult ProcessMessage()
{
return new ProgressiveResult();
}
You have to return false in click event handler to cancel submitting the form:
<input type="submit" value="Upload File" name="btnUpload" onclick="progressStatus(); return false;"/>
