Hi,

You can write a method which will check the available files and return a bool value. So using this you can verify the availability. A sample snippet is as follows,

    protected bool IsFileExist(string fileName)
        {
            DirectoryInfo di=new DirectoryInfo (Server.MapPath("ProductThumbnails"));
            FileInfo[] files=di.GetFiles();
            foreach (FileInfo file in files)
            {
                if (file.Name==fileName)
                {
                    return true;
                }
            }
            return false;

        }

Regards,
raaj
