Opening means just showing redirecting to the file and prompting for a download ? or opening the file using any file methods ? Can you post the code you used for this ?

the path you are giving must be of local file system.Try to download the file at client side and then open it.

this is the code i'm using in it. i have to open the file in any way(download or open) DirectoryInfo di = new DirectoryInfo(Server.MapPath("Data/")); string pa = di.ToString(); if (di.Exists == false) { di.Create(); } FileStream fs = new FileStream(di + "/" + DropDownList1.SelectedItem.Text, FileMode.Open); fs.Seek(0, SeekOrigin.Begin); fs.Close(); ProcessStartInfo psi = new ProcessStartInfo(di + "/" + DropDownList1.SelectedItem.Text); Process.Start(psi);

This looks fine in the case of desktop applications. But in ASP.NET , Process.Start() can't start a process in clients machine, because ASP.NET it works on server. You can redirect to the file instead, which forces browser to open a save dialog box, and user can download the file to his/her system. Use

Response.Redirect("Data/" + DropDownList1.SelectedItem.Text);

Out of Topic : There is no need to use DirectoryInfo for checking directory existence. Directory class provides a static methods which checks directory existence.
