weird....differ ent size between uploading and downloading???

[TJ]

Hi,

I've written code web-based uploading and downloading.
Here is some code for it.

For saving file into MS-SQL database,
SaveFileIntoDB( HttpPostedFile file) {
int fileLength = file.ContentLen gth;
byte[] fileContent = new byte[fileLength];
int lastPos = file.FileName.L astIndexOf('\\' );
fileName = file.FileName.S ubstring(++last Pos);
file.InputStrea m.Read(fileCont ent,0,fileLengt h);
String fileContentType = file.ContentTyp e;

// Save fileLength,file Name and fileContent into MS-SQL database
// data type of fileLength(colu mn name : filelength) is int
// data type of fileName(column name : filename) is varchar(100)
// data type of fileContent(col umn name : filecontent) is image.
// data type of fileContent type(column name : contenttype) is
varchar(100)

DB.Save(......) ;

}

For downloading the file from the DB.

Download() {

// Fetch the file info into db variable from the DB.

int filesize = Convert.ToInt32 (db["filesize"].ToString());
byte[] fcontent = db["fileconten t"] as byte[];
ms = new MemoryStream();
ms.Position = 0;
ms.Write(fconte nt,0,fcontent.L ength);
Response.Append Header("Content-Disposition",
"filename=" + db["filename"].ToString());
Response.Conten tType = db["contenttyp e"].ToString();
Response.Output Stream.Write(ms .GetBuffer(),0, Convert.ToInt32 (ms.Length));
}

For saving the file info to the sql db, it worked as I expected. Also, when
I tried to download the file that I saved into the db, it worked, HOWEVER,
when I checked the filesize, it was DIFFERENT. Do you have any idea why?

For example,

Suppose that I uploaded "A.exe" file into the sql db.
The file size of A. exe was 5113 Bytes.
If I downloaded the A.exe, and then when I checked the file size,
it was 5,896 Bytes.
I think that it should be same size since it was same file.
Always whenever I download the file that I've uploaded, the file size is
slighlty bigger than uploaded file. I really couldn't find any reason....
After downloading, the file seems like working well, but I guess it must be
something wrong since it was different file size.

If you could give any ideas about this issue, I really appreciate it.

Thanks.
