array list

[Hrvoje Voda]

DataRow[] drow = db.dataSetLogo.Logo.Select("LogoName = '" +
cPicList.SelectedItem.ToString() + "'");

if (drow.Length > 0)

{

try

{

picLogo.Image = Image.FromFile(drow[0].ToString ()); *

PicInfo(drow[0].ToString ());

}

catch (Exception x)

{

MessageBox.Show(x.Message);

}

}



I'm using this code to get a name of a logo. But, I get an error on *. How
to get a single name through an array list?

What is the error you are seeing? Is it an index out of range exception?
Which could be the case if your drow array is empty. You should always
program defensively and assume that there could be nothing in the array,
rather than trying to access an element which does ot exist.

Hi,

What the * is doing there? you should be getting a compiler error as this is
a syntax error.

what drow[0].ToString () return?

Hrcko,

Since you are guarding against an array of length zero (what if it's null),
I would guess that the file doesn't exist that your tring to load since you
are not using System.IO.File.Exists before attempting to load an image OR
from MSDN:

If the file does not have a valid image format or if GDI+ does not support
the pixel format of the file, this method throws an OutOfMemoryException
exception.
