1.檔案一定是要mp3格式(wav檔不行)
2.檔案請放在「Resources」之下,本例為了跟其他資源區分,放在Resources/raw之下,
(有a1.mp3,a2.mp3....)
3.play sound的語法
A.用MediaPlayer:
var player =MediaPlayer.Create(ApplicationContext,Resource.Raw.a1);
player.Start();
B.用RingToneManager:
var uriString="android.resource://" + your_package_name + "/" +Resource.Raw.a1;
var uri=Android.Net.Uri.Parse(uriString);
Ringtone r = RingtoneManager.GetRingtone(ApplicationContext, uri);
r.Play();

以上,大家加油了!!
AndroidManifest.xml
----------------------------------
...
...
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE" />
-----------------------------------
in android app Activity c# :
---------------------------------
var wifiManager = (WifiManager)GetSystemService(Context.WifiService);
MulticastLock mLock = wifiManager.CreateMulticastLock("lock");
mLock.Acquire();
using (var udpClient = new UdpClient(你要聆聽的port number)) {
var asyncResult = udpClient.BeginReceive(null, null);
var timeToWait = TimeSpan.FromSeconds(30);//30秒,超過就結束
asyncResult.AsyncWaitHandle.WaitOne(timeToWait);
if (asyncResult.IsCompleted) {
IPEndPoint remoteEP = null;
byte[] receivedData = udpClient.EndReceive(asyncResult, ref remoteEP);
string msg = System.Text.Encoding.UTF8.GetString(receivedData);
Console.WriteLine($"get end point message:{msg}");
mLock.Release();
} else {
mLock.Release();
Console.WriteLine("UDP failed!!!!!!");
}
}
