BeginRead() function question

    class Program
    {
        static byte[] asyncbytes;
        static FileStream fileS;
        static FileInfo file;
 
        static void Main(string[] args)
        {
 
            file = new FileInfo(@"c:\akshay.dat");
            fileS= file.Open(FileMode.OpenOrCreate, FileAccess.ReadWrite);
 
 
            string str = "hello akshay joshi";
 
            byte[] bytes = Encoding.Default.GetBytes(str);
            fileS.Write(bytes, 0, bytes.Length);
 
            AsyncCallback callback = new AsyncCallback(func);
 
 
            asyncbytes = new byte[18];
            Console.WriteLine("\n\nBegin reading....");
            fileS.BeginRead(asyncbytes, 0, 18, callback, asyncbytes);
            Console.ReadKey();
        }
        static void func(IAsyncResult result)
        {
            Console.WriteLine("Read.");
            fileS.EndRead(result);
            foreach (byte b in (byte[])result.AsyncState)
                Console.Write((char)b);
        }
    }

Why only spaces are getting printed instead of "hello akshay joshi" ?
I can open the dat file and see "hello akshay joshi" is there !

Do you mean to be reading the data as bytes? If so you aren't going to get textual output... If you want to be doing that read the data as a char[]

OOPS my bad, I forgot to set the position of stream to 0 before reading.
Problem solved !

I was just going to say that. I'm too late though I guess.
