注解

Dashes类的属性描述了交替虚线和间隙的长度。The Dashes property of this class describes the length of alternating dashes and gaps. 集合中的值是的Thickness Pen的倍数。The values in the collection are in terms of multiples of the Thickness of the Pen. 例如, 的1数组指定长度为2 ( * Thickness2 * ),1后跟长度为Thickness() 的间隔。For example, an array of 1,2 specifies a dash of length (1 * Thickness) followed by a gap of length (2 * Thickness).

备注

绘制的短划线的实际长度取决于添加到虚线每个DashCap端点的的样式。The actual length of the dash that is drawn depends on the style of DashCap that is added to each end of the dash. DashCap Square默认值为。PenThe default DashCap value for a Pen is Square. 这会导致一端在笔笔划的每一端添加一一半, 即线条粗细的一半。This causes an end cap that is one half the thickness of the line to be added onto each end of the pen stroke. (请参阅 PenLineCap 查看示例。)因此, 如果0指定的 * DashCap0 DashCap 2数组和正方形, 则实际短划线长度将为 ( * Thickness) + (2)。(See PenLineCap for an example.) Therefore, if you specify an array of 0, 2 and a square DashCap, the actual dash length will be (0 * Thickness) + (2 * DashCap).

如果集合中有奇数个值, 则会将值解释为在生成偶数个值后重复出现。If there are an odd number of values in the collection, the values are interpreted as if they had been repeated once to produce an even number of values. 例如2, 包含、35的集合与包含235``2、、、5的集合相同。3For example, a collection containing 2,3,5 is interpreted the same as a collection containing 2,3,5,2,3,5.

数组中的负值被解释为其绝对值。Negative values in the array are interpreted as their absolute value.
