Question

In Asp.net (c#),i’m not able to catch exception(FileNotFoundException) properly… i don’t know the reason..Actually File s not there..But catch statement fails to catch the exception..
here is the code..

try
{
System.Drawing.Image imgg1 = System.Drawing.Image.FromFile(Server.MapPath("").ToString() + "\\images\\img1.jpg");
}
catch (FileNotFoundException)
{
    Response.Write("<script>alert('Please Select and upload Student's Photo');</script>");
}

Answer 1

Are you sure that’s the exception your getting?

You should try to replace the FileNotFoundException to just Exception and check what exception is being trown.

EDIT:
Q1: In the debug mode, is the code actually entering the catch session?

Could you rebuild (Ctrl+Shift+B in Visual Studio) that code?

Your actually writing a code that will fail
there’s an ending quote in here:

alert('Please Select and upload Student's Photo');

See in the sintax highlighter
replace for this

alert('Please Select and upload Student\'s Photo');
