Gets or sets the collection of dashes and gaps in this DashStyle.
Assembly: PresentationCore (in PresentationCore.dll)
This collection describes the length of alternating dashes and gaps. The values in the collection are in terms of multiples of the Thickness of the Pen. For example, an array of 1,2 specifies a dash of length (1 * Thickness) followed by a gap of length (2 * Thickness).
The actual length of the dash that is drawn depends on the style of DashCap that is added to each end of the dash. The default DashCap value for a Pen is Square. This causes an end cap that is one half the thickness of the line to be added onto each end of the pen stroke. (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).
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. For example, a collection containing 2,3,5 is interpreted the same as a collection containing 2,3,5,2,3,5.
Negative values in the array are interpreted as their absolute value.
