在wpf中如何在列表框中绑定动态文本框

public class MainViewModel : INotifyPropertyChanged
{
    private string _dynamicText;

    public string DynamicText
    {
        get { return _dynamicText; }
        set
        {
            _dynamicText = value;
            OnPropertyChanged(nameof(DynamicText));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}
