获取或设置一个值，该值指示在适当的时候数字显示框（也称作 up-down 控件）中是否显示千位分隔符。
public:
property bool ThousandsSeparator { bool get(); void set(bool value); };C#
public bool ThousandsSeparator { get; set; }member this.ThousandsSeparator : bool with get, setPublic Property ThousandsSeparator As Boolean如果在适当的情况下在数字显示框中显示千位分隔符，则为 true；否则为 false。 默认值是 false。
下面的代码示例创建并初始化控件 NumericUpDown ，设置其一些常见属性，并允许用户在运行时更改其中的一些属性。 此代码假定已将三 CheckBox 个控件放置在窗体上，并且已实例化其 Click 事件的处理程序。 、 DecimalPlacesThousandsSeparator和 Hexadecimal 属性在每个检查框的 事件上Click设置。
