For file size use the FileInfo.Length Property[^].

Hi ...

Try the below code;

C#

FileUpload1.SaveAs(Server.MapPath("uploads\\").ToString () + FileUpload1.FileName);
           double filelength = FileUpload1.FileContent.Length;

Solution 2

You can use FileInfo.Length. It gives file size in bytes.

FileInfo fileInfo = new FileInfo("Input.txt");
Console.Write(string.Format("{0} ({1}B)", fileInfo.Name, fileInfo.Length));

Manas what if ihave show it interms of KB or MB?

Manas Bhardwaj 4-Jul-12 8:08am

Shouldn't be difficult:
1024 Bytes = 1 KiloByte
1024 KiloBytes = 1 MegaByte

Well there are 1024 bytes in 1 KB and 1024 KB in 1 MB so some simple division.

Too slow, that will teach me to do some work :)
