我整天都在努力使这项工作正常进行,但似乎我做不到。
我做的第一件事是用系统上安装的声音列表填充一个组合框。一旦组合框正确填充了所有声音,我就无法从组合框中选择任何值。
问题出在哪里?
public class ComboData
{
public int _Id { get; set; }
public string _Name { get; set; }
}
public void accSettings()
{
SpeechSynthesizer speaker = new SpeechSynthesizer();
List<ComboData> ListData = new List<ComboData>();
int a = 1;
foreach (InstalledVoice voice in speaker.GetInstalledVoices())
{
VoiceInfo info = voice.VoiceInfo;
ListData.Add(new ComboData { _Id = a, _Name = info.Name });
a++;
}
VoiceList.ItemsSource = ListData;
VoiceList.DisplayMemberPath = "_Name";
VoiceList.SelectedValuePath = "_Id";
VoiceList.SelectedValue = "1";
}
这是 XAML
<ComboBox x:Name="VoiceList" Margin="10,0,0,0" Width="200" HorizontalAlignment="Left"/>
