Solution 1

Here is the solution

HttpPostedFile file = fileImage.PostedFile;
byte[] bytPDF = new byte[file.ContentLength];
Stream objStream;
objStream = file.InputStream;
objStream.Read(bytPDF , 0, file.ContentLength);
string fileName = file.FileName.Trim();

After that you can save the byte into the DB

Why do you recommend storing the file in the database? Why not store it directly on the disk.
Saving and retrieving files from database will require extra overhead which is not at all required here.

Chill Ankur, OP asked to save file in DB.

What you say is another alternative for sure but has it's own pros-cons that I am sure you know too. :)

Yes sandeep, you are right. Thanks for your vote.

Oh, I missed that part. Read the subject and then read the content too quickly.

What you say is another alternative for sure but has it's own pros-cons that I am sure you know too.
I do and in this case my recommendation would be to store it on the disc drive rather than database.

But we both know, customers can be rigid at times! ;)

I can't agree any more. :)

I am sorry, I didn't read the question properly. I think I need a cup of coffee. :)

Solution 2

You need to use a File Upload Control[^] (more details - MSDN link[^]).
You may also add a filter for file types[^].

Save the file on the disk, save the path in the database. And whenever you need to give a link to the path, retrieve the path from database and give a link to the client.

There are various examples on the web, you just need to search.

Hope this helps!

For Upload

if (Fup1.FileName.Length > 0)
                {
                    a = Fup1.FileName.Split('.');
                    fileName = Convert.ToString(System.DateTime.Now.Ticks) + "." + a.GetValue(1).ToString();
                    FilePath = Server.MapPath(@"~\FolderToSave");
                    Fup1.SaveAs(FilePath + @"\" + fileName);

                    FullName = FilePath + @"\" + fileName;
                  
                    //Save filepath in your database;

                }

For showing PDF in your web page you can use iframe.

Hope this can help you.
