UI无法更新foreach循环C＃WPF中首先播放的声音

Question

I have made a card game that gets and shows player cards from resources in a UI using a foreach loop which works fine. I have recently added a card sound as well so that a sound would be played before each image is shown in the UI. However, the sounds are always played first and then the images are shown. A bit annoying...

I use sound player and playsync(). How do I force the GUI to update? (between the sounds)

Here is some of the code...

Starts with

//loop
foreach (var player in playerGUIs)....
//Call the sound Card_Sound(); //See below

//Update image player.img1.Source = new BitmapImage(new
Uri(("/Utilities;Component/Resources/" + card_file + ".png"),
UriKind.Relative));


private void Card_Sound()
    { //Play sound System.Threading.Thread.Sleep(800); // First sleep 800 milliseconds

using (FileStream stream = File.Open(@"Resources\dealingcard.wav",
FileMode.Open)) {
    SoundPlayer myNewSound = new SoundPlayer(stream);
           myNewSound.Load();
           myNewSound.PlaySync(); }

}

您是否尝试过Play（），PlaySync（）会阻止UI（如果在UI线程上运行）？
