如何在xamarin窗体中自定义滑块？

public class CustomSlider : Slider
{
    // 添加自定义属性和事件
}

public class CustomSlider : Slider
{
    public static readonly BindableProperty CustomColorProperty =
        BindableProperty.Create(nameof(CustomColor), typeof(Color), typeof(CustomSlider), Color.Default);

    public Color CustomColor
    {
        get { return (Color)GetValue(CustomColorProperty); }
        set { SetValue(CustomColorProperty, value); }
    }

    // 添加其他自定义属性和事件
}
