在 C# 中的 Combobox 中播放声音

Question

I'm new in C# programming, I created a combobox with items and I want that items to play sound when i chose one, like this , or that.

I'm using Visual Studio 2015.

Could would be in methods play1 and play2

private void AudioComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 1"))
            {
                play1();
            }

            else if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 2"))
            {
                play2();
            }
        }


        private void play1()
        {
        }
        private void play2()
        {  
        }

Answer 1

You can use MediaElement or the new AudioGraph to play sounds in UWP.

MediaElement is the simpler approach, which has the disadvantage of causing the music stop on Mobile devices, so it is really not too appropriate your purpose.

MediaElement player = new MediaElement();
var stream = await yourSoundFile.OpenAsync(Windows.Storage.FileAccessMode.Read);
player.SetSource(stream, file.ContentType);
player.Play();

AudioGraph is specifically created for sound effects in UWP apps and is the best choice for you. There is a quick and simple tutorial on Loek van den Ouweland's blog , so I definitely recommend you to check it out. Basically you need to create an AudioGraph instance and with it AudioFileInputNode s for each of the sounds you need.

This should work

private void AudioComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 1"))
            {
                play1();
            }

            else if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 2"))
            {
                play2();
            }
        }


        private void play1()
        {
            SoundPlayer simpleSound = new SoundPlayer("sound1.wav");
            simpleSound.Play();
        }
        private void play2()
        {  
            SoundPlayer simpleSound = new SoundPlayer("sound2.wav");
            simpleSound.Play();
        }
