示例1: Send
public async void Send(byte[] fileBytes)
{
try
{
if (Speakers != null && Speakers.Count > 0 && fileBytes != null)
{
//iterate through the speakers and send out the media file to each speaker
foreach (Speaker speaker in Speakers)
{
StreamSocket socket = speaker.Socket;
if (socket != null)
{
IOutputStream outStream = socket.OutputStream;
using (DataWriter dataWriter = new DataWriter(outStream))
{
//write header bytes to indicate to the subscriber
//information about the file to be sent
dataWriter.WriteInt16((short)MessageType.Media);
dataWriter.WriteInt32(fileBytes.Length);
await dataWriter.StoreAsync();
//start from 0 and increase by packet size
int partNumber = 0;
int sourceIndex = 0;
int bytesToWrite = fileBytes.Length;

await dataWriter.StoreAsync();

//Finally DetachStream

// then wait for the audio to be sent to us
