Friend we are not here to fix your silly problems. BTW colon (:) is not valid for file names. — Pradeep

Three possibilities jump out at me.

: isn't a valid character in filenames on Windows systems.
Directory ~/img//1/1/ doesn't exist.
It doesn't like the double forward slash.

Try like this:

var path = MapPath("~/img");
var datePart = DateTime.Now.ToString("dd-MM-yyyy-HH-mm-ss-");
var filename = Path.Combine(path, datePart + FileUpload1.FileName);
FileUpload1.SaveAs(filename);

What needs to be included to Use the Path as class

Darin Dimitrov Over a year ago

@jagdeep, the Path class is defined in the System.IO namespace.
