I'm trying to create text file in memory and write it byte[]. How can I do this?

public byte[] GetBytes()
{
    MemoryStream fs = new MemoryStream();
    TextWriter tx = new StreamWriter(fs);

    tx.WriteLine("1111");
    tx.WriteLine("2222");
    tx.WriteLine("3333");

    tx.Flush();
    fs.Flush();

    byte[] bytes = new byte[fs.Length];
    fs.Read(bytes,0,fs.Length);

    return bytes;
}

But it does not work because of data length

How about:

byte[] bytes = fs.ToArray();
