Once the files have been uploaded, in response I'm getting only .jpg as file name not the uploaded file name like below
"Files":{"file":[{"filename":".jpg","fileid":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx=-3679219-100000000","filesize":"3679219","msg":"No error"}]}
It is strange that you are not getting back the filename, but it should not really mater, as long as the filesize is correct - otherwise it is a sign that the file might be corrupted.
It would be interesting to know how you upload the file - maybe we could identify the couse of name stripping.

I am developing a .NET intranet site which will enable the user to see a list of files (file details stored in DB) and link to the actual PDF/XML/XLS and open it... kind of like a table of contents for the network.
During data entry, the user enters various data about a document, then browses to the file on the network and selects it using the asp:FileUpload. The codebehind then saves the network path to the DB. There is alot of overhead here because i'm sending the file to the server but never use it.
Everything has been working fine until someone tries to use a large PDF file then I get the dreaded MAXIMUM REQUEST LENGTH EXCEEDED error... So I'm trying to find a solution here... I do not need the actual file.. just the path and filename.
I know not all browsers send the full path but our systems have older browsers so everything is working fine now, but will probably break soon.. which is another reason to find a different solution.
I've looked into Javascript to pull the path but that won't work...
Any other ideas? Other ways to just grab the path and filename? (besides manually typing it in to a Text field)
Thanks,
Todd.

How to get the full path of a file from asp: file upload?
string filename = Path.GetFileName(FileUpload1.FileName);//file name
string path= Server.MapPath(filename);//path
I have developed File Upload web page in ASP.NET. Now user can rename a .exe file to txt or some other extension and upload the same. I want to restrict that. How I can implement that in ASP.NET?
The only safe way to do this is to get the byte [] from the file that has been posted and examine it to determine if the file is indeed in one of the formats you allow the user to upload. You don't need to save the file, you can just get the byte[] from the HttpPostedFile object.
Other than examining the content (looking for magic numbers, for example) there isn't an infallible way to make sure that the user is not attempting to upload something that you don't allow.
I am using a File Upload control in MVC project.
<input type="file" name="file" id="Ids2" style="float:right"/>
I get the following error when I try to save the file (TestDocument.txt) in the database. Lets say I click on the upload button and then browser to location - "c:\TestDocument.txt" - and try to upload it, I get this error..
Could not find file 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\TestDocument.txt'.
Edit:(I am passing filename from the input type "file" value)
session.Advanced.DatabaseCommands.PutAttachment(id,null,
File.ReadAllBytes(#fileName), optionalMetaData);
Even though I select the text file from C:\ location, it always look for the file in the above "C:\Program Files (x86)\Co....." location. How do I make it take the file from its original location. Thanks for the help.
You can't just pass the filename of the file to the server and expect to open the file using that filepath. The path passed is on the clients local machine, but you are trying to open the file on the server.
You need a form element to post the actual file contents to the server.
Phil Haack has a good article with information on how to upload a file using MVC.

Salvete! When we set up the asp.net file-uploading control called "NeatUpload", it saves its files to a temporary location, either "YOUR_APP_ROOT /app_data/NeatUpload_Temp/", if the directory is writable, or to the system's temp folder. However, the demo does not seem to actually upload any files, nor does it include an example for saving the files to a particular directory.
How do we save the file we have uploaded and move the uploaded file to a particular folder? My only clue from the documentation is that it has to do with UploadStorageProvider, but I need some help to implement this.
if you read the documentation 3.3 point 6 :
In your codebehind file, process the uploaded file. If you are using
the InputFile control, the uploaded file's client-specified name, MIME
type, and contents can be accessed via inputFileId.FileName,
inputFileId.ContentType, and inputFileId .FileContent, respectively.
If you want to keep the uploaded file, you must use the
inputFileId.MoveTo()method to move the uploaded file to a permanent
location. If you do not, NeatUpload will automatically remove the
uploaded file at the end of the requestto ensure that unwanted files
do not fill up the filesystem. The following code will put the
uploaded file in the application's root directory (assuming sufficient
permissions):
and so on. I hope this is what you are after.
I have problem with uploading files. I followed these instructions: http://symfony.com/doc/current/cookbook/doctrine/file_uploads.html and everything is working fine, but I want to save uploaded files in a folder that is not public and with random name and then send it to the browser in original name.
I know how to put file in non public folder with random name and how to save original name to database, but what should I do next for getting this file content and send it to browser with original name? How to achieve that?
Store the hidden path in the database, then just read it in your php script that is public available and send your file to a user, if you don't how to send files in php, you can find it out here on stackoverflow.
