Write string to a stream using utf16 encoding

Question

My code:

        public static void DoStrumienia (string pString, Stream pStream)
        {
              if (pStream == null) throw new ArgumentNullException ();

              BinaryWriter bw = new BinaryWriter (pStream);

              int rozmiar = pString.Length;
              bw.Write (rozmiar);

              for (int i = 0; i < rozmiar; i++)
              {
                    bw.Write (pString[i]);
              }

              bw.Flush ();
        }

It writes string to a stream, but it writes using UTF8 encoding. How to it with UTF16?

Solution

System.Text.Encoding encoding = System.Text.Encoding.Unicode; 
BinaryWriter bw = new BinaryWriter (pStream, encoding);

Why are you writing one character at a time?

Because it's the only way what I know for now.

Why i should use Big Endian encoding? It doesnt make sense to me. I just fixed line: bw.Write (pString[i]); to bw.Write ((ushort)pString[i]); and maybe it will be works.

x86, so i use LE. Just casting to a USHORT make everything OK. Looks like BinaryWriter uses UTF8 encodinf for chars. So ushort prevents it, and all works ok. Anyway thank you for ur answer.

@zgnilec System.Text.Encoding.Unicode should be UTF-16 (little endian) encoding. Use that one if that's what you need.

Oh sorry, im little tired, didnt even looked u set stream to specyfic encoding :) Just thought u did conversion or smth:O need go to sleep, u got best answer, thank you.
