我是 C# 新手，但我不明白為什么我無法訪問 MainWindow 類中的列表。public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); List<EqualisationSetting> equalisationSettings = new List<EqualisationSetting> { new EqualisationSetting { LowerFrequencyBound = 20, UpperFrequencyBound = 250, DecibelRatioChange = 0 }, new EqualisationSetting { LowerFrequencyBound = 250, UpperFrequencyBound = 4000, DecibelRatioChange = 0} }; ItemsCountroller.ItemsSource = equalisationSettings; } private void AddFrequencyBoundButton_Click(object sender, RoutedEventArgs e) { equalisationSettings.add(new EqualisationSetting(); } }它拋出“當前上下文 SoundEditor 中不存在名稱‘equalizationSettings’”。

這是因為您的變量位于 MainWindow() 方法內部。嘗試這個：
public partial class MainWindow : Window
{
List<EqualisationSetting> equalisationSettings;
public MainWindow()
{
InitializeComponent();
equalisationSettings = new List<EqualisationSetting>
{
new EqualisationSetting { LowerFrequencyBound = 20, UpperFrequencyBound = 250, DecibelRatioChange = 0 },
new EqualisationSetting { LowerFrequencyBound = 250, UpperFrequencyBound = 4000, DecibelRatioChange = 0}
};
ItemsCountroller.ItemsSource = equalisationSettings;
}
private void AddFrequencyBoundButton_Click(object sender, RoutedEventArgs e)
{
equalisationSettings.add(new EqualisationSetting();
}
}
