        private byte[] FileContent(string fileName) 
        { 
            using (FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.Read)) 
            { 
                try 
                { 
                    byte[] buffur = new byte[fs.Length]; 
                    fs.Read(buffur, 0, (int)fs.Length); 
                    return buffur; 
                } 
                catch (Exception ex)
