Xamarin使用可观察集合词典进行表格设置绑定

它看起来像:

myNoResultsLabel.SetBinding(Label.IsVisibleProperty, "NameOfProperty", BindingMode.Default, new MyEmptyListIsTrueConverter());

转换器:

public class MyEmptyListIsTrueConverter: IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if ((cast)value == value.count > 0)
        {
            return true
        }
        else 
        {
            return false;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
