Get game being streamed from user's activity on Discord

I'm writing a discord bot in .net, and I need to get the name of the game being streamed by a user.
In discord.py, this is possible with https://discordpy.readthedocs.io/en/rewrite/api.html?highlight=guild#discord.Streaming.details.
I'd like to do this in discord.net, but 'Activity', along with Activity cast to Game and StreamingGame, all return the name of the stream (when streaming), not the actual name of the game. (RichGame gives a null reference exception.)
The game being played is visible when viewing a streaming user on Discord, but as far as I could see, not in the API. So how does discord.py get it?
I checked other libraries and it seems discord.py is the only one supporting it.
I tried to read the source code, but I'm not at all well-versed enough in python to understand it.
Example below:
var user = _client.GetGuild(0).GetUser(0);
Console.WriteLine($"Activity - {user.Activity.Name}");
Console.WriteLine($"Type - {user.Activity.Type}");
var Game = user.Activity as Game;
Console.WriteLine($"Game - {Game.Name}");
var StreamingGame = user.Activity as StreamingGame;
Console.WriteLine($"StreamingGame - {StreamingGame.Name}");
Returns:
Type - Streaming
Game - !giveaway ... Fallout 2 war eh das beste...
StreamingGame - !giveaway ... Fallout 2 war eh das beste...
Querying the the twitch API works, but seems excessive, considering it's available in the discord.py library.
Any help would be appreciated, thank you.

String, u downloaded from service has a xml format? If not, cruisexmlDocument.LoadXml(result); doesn't take effect, it just loads in memory XML string.

Just download your content read it as string, and write it. You don't need to handle it as XML excplicitly, unless you need to do some verification that it is a valid XML in some way. Other than that, just download it and write it. Make sure you have permissions to write to your path.
var httpClient = new HttpClient();
var result = httpClient.GetAsync("your url").Result;
System.IO.File.WriteAllText(#"C:\yourxml.xml", result.Content.ReadAsStringAsync().Result);

Text To Speech with SAPI: Custom Language

I'm from Greece and I want to make an application which will use SAPI to interact with the user, but I can't find a way to change the language of SAPI from English to Greek.
My OS is by default Greek & English, and I have SAPI SDK installed; the Greek Language is supported by SAPI.
The problem is that SAPI doesn't automatically recognise the language passed to it, and reverts to saying the individual letters one-by-one.
Here is the code I'm using, with English text:
using SpeechLib;
SpVoice voice = new SpVoice();
voice.Speak("Pdf File Successfully Installed", SpeechVoiceSpeakFlags.SVSFlagsAsync);
voice.WaitUntilDone(30000);
This works, but when I pass Greek text to the function (eg "Να ενα κειμενο"), I see the problem occur.

You can set a language by passing SSML to the Speak API, and including the xml:lang attribute.
For example this should work:
SpVoice voice = new SpVoice();
voice.Speak(
"<speak version='1.0' xmlns='http://www.w3.org/2001/10/synthesis' xml:lang='el-GR'>"
+ "Να ενα κειμενο"
+ "</speak>",
SpeechVoiceSpeakFlags.SVSFlagsAsync|SpeechVoiceSpeakFlags.SVSFIsXML);
voice.WaitUntilDone(30000);
You can also switch language mid-speech. The documentation has this example:
<speak version="1.0"
xmlns="http://www.w3.org/2001/10/synthesis"
xml:lang="en-US">
For English, press 1.
<voice xml:lang="fr-FR" gender="female">
Pour le français, appuyez sur 2 </voice>
</speak>

Playing Audio in .Net / C#

I'm an experienced MFC programmer of many years, who for the more recent years has been developing commercial apps in Objective C for Mac and iOS - I'm trying to get up to speed with .Net and C# (as I'm soon going to be required to convert one of my commercial apps from Mac to PC).
I've now worked my way through a couple of books and as an exercise to get more familiar with .Net (and C#) I've decided to have a go at converting one of my none commercial apps to .Net as a learning exercise and all is going well (interface is working, data structures all good) but I need to be able to play audio.
My Mac app generates audio from a series of mathematical formula - imagine a wave generator - not quite the same but similar. On the Mac I generate the audio as 16 bit signed raw audio, use Core Audio to setup audio output routing and then get a callback whenever a new buffer of audio is required for the audio routing (so I can generate the audio on the fly).
I need to do the same on the PC. Unfortunately I find MSDN documentation to be a case of "Can't see the wood for the trees" as there is such a vast amount of documentation. I can find classes that will let me load and play mp3/wav etc files, but I need to generate the audio realtime. Can anyone point me in the right direction to find something that will allow me to fill buffers on the fly as it plays them?
Thx

I have used this sample in several projects with good results. It is basically a .Net wrapper for Windows Waveform Audio API using P/Invoke.
Other choices:
NAudio
Sound Player class from .Net framework

I have created a class that can play audio given Stream derivate as an input. So if you are able to pack your sound-generator into the Stream compatible interface, it could be suitable for you.
How I did it - I used unmanaged waveOut* methods from old Windows multimedia API, and handled the playback from there.
Other options - that I am aware of - use waveOut directly, from this: http://windowsmedianet.sourceforge.net/ or write your own DirectShow source filter, but that might be too complicated, since it has to be written in c++.
If you are interested in giving my component a try, I can make it available to you at no charge, since I need it beta tested (I only used it in several of my projects).
EDIT:
Since there are 6 upvotes to the question, I am offering my component free of charge (if you find useful) here: http://dl.dropbox.com/u/10020780/SimpleAudioPlayer.zip
Maybe you can reflect on it :)

I use Audiere to accomplish this and find it works very well.
It's a C++ lib really, but there are a set of bindings available for C#.
For more info, see the question I asked.

You should have a look at FMOD which allows this kind of operation and much more. It is also cross platform which can be interested if you are also working on a mac.

Alvas.Audio has 3 audio players: Player
player.FileName = "123.mp3";
player.Play();
PlayerEx
public static void TestPlayerEx()
{
PlayerEx plex = new PlayerEx();
plex.Done += new PlayerEx.DoneEventHandler(plex_Done);
Mp3Reader mr = new Mp3Reader(File.OpenRead("in.mp3"));
IntPtr format = mr.ReadFormat();
byte[] data = mr.ReadData();
mr.Close();
plex.OpenPlayer(format);
plex.AddData(data);
plex.StartPlay();
}
static void plex_Done(object sender, DoneEventArgs e)
{
if (e.IsEndPlaying)
{
((PlayerEx)sender).ClosePlayer();
}
}
and RecordPlayer
public static void TestRecordPlayer()
{
RecordPlayer rp = new RecordPlayer();
rp.PropertyChanged += new PropertyChangedEventHandler(rp_PropertyChanged);
rp.Open(new Mp3Reader(File.OpenRead("in.mp3")));
rp.Play();
}
static void rp_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
switch (e.PropertyName)
{
case RecordPlayer.StateProperty:
RecordPlayer rp = ((RecordPlayer)sender);
if (rp.State == DeviceState.Stopped)
{
rp.Close();
}
break;
}
}

SpeechSynthesizer .NET control pitch

I'm trying to change the pitch of spoken text via SSML and the .NET SpeechSynthesizer (System.Speech.Synthesis)
SpeechSynthesizer synthesizer = new SpeechSynthesizer();
PromptBuilder builder = new PromptBuilder();
builder.AppendSsml(#"C:\Users\me\Documents\ssml1.xml");
synthesizer.Speak(builder);
The content of the ssml1.xml file is:
<?xml version="1.0" encoding="ISO-8859-1"?>
<ssml:speak version="1.0"
xmlns:ssml="http://www.w3.org/2001/10/synthesis"
xml:lang="en-US">
<ssml:sentence>
Your order for <ssml:prosody pitch="+30%" rate="-90%" >8 books</ssml:prosody>
will be shipped tomorrow.
</ssml:sentence>
</ssml:speak>
The rate is recognized: "8 books" is speaken much slower than the rest, but no matter what value is set for "pitch", it makes no difference ! Allowed values can be found here:
http://www.w3.org/TR/speech-synthesis/#S3.2.4
Am I missing something or is changing the pitch just not supported by the Microsoft Speech engine ?
fritz

While the engine SsmlParser used by System.Speech accepts a pitch attribute in the ProcessProsody method, it does not process it.
It only processes the range, rate, volume and duration attributes. It also parses contour but is processed as range (not sure why)...
Edit: if you don't really need to read the text from a SSML xml file, you can create the text programatically.
Instead of
builder.AppendSsml(#"C:\Users\me\Documents\ssml1.xml");
use
builder.Culture = CultureInfo.CreateSpecificCulture("en-US");
builder.StartVoice(builder.Culture);
builder.StartSentence();
builder.AppendText("Your order for ");
builder.StartStyle(new PromptStyle() { Emphasis = PromptEmphasis.Strong, Rate = PromptRate.ExtraSlow });
builder.AppendText("8 books");
builder.EndStyle();
builder.AppendText(" will be shipped tomorrow.");
builder.EndSentence();
builder.EndVoice();
