Dashed lines with custom caps

You can set properties of the Pen object to create custom lines. For example, you can use the DashStyle enumerated property to draw dashed lines using a predefined pattern, and you can even create custom dash patterns by assigning an array of Single values to the DashPattern property. The StartCap and EndCap properties can take an enumerated value and let you change the shape of the starting and ending point of the line so that you can easily create arrows or other common shapes. Here’s a code that creates several lines with different styles:

' This statement assumes that you have imported the System.Drawing namespace' This code should run inside a Windows Form classDim gr As Graphics = Me.CreateGraphicsDim p1 As New Pen(Color.Black, 3)p1.DashStyle = Drawing.Drawing2D.DashStyle.Dashgr.DrawLine(p1, 10, 10, 200, 10)p1.DashStyle = Drawing.Drawing2D.DashStyle.DashDotgr.DrawLine(p1, 10, 30, 200, 30)p1.DashStyle = Drawing.Drawing2D.DashStyle.DashDotDotgr.DrawLine(p1, 10, 50, 200, 50)p1.DashStyle = Drawing.Drawing2D.DashStyle.Dotgr.DrawLine(p1, 10, 70, 200, 70)' Create a custom dash pattern.Dim sngArray() As Single = {4, 4, 8, 4, 12, 4}p1.DashPattern = sngArraygr.DrawLine(p1, 10, 90, 200, 90)' Display pens with nondefault caps.Dim p2 As New Pen(Color.Black, 8)p2.StartCap = Drawing.Drawing2D.LineCap.DiamondAnchorp2.EndCap = Drawing.Drawing2D.LineCap.ArrowAnchorgr.DrawLine(p2, 280, 30, 500, 30)p2.StartCap = Drawing.Drawing2D.LineCap.RoundAnchorp2.EndCap = Drawing.Drawing2D.LineCap.Roundgr.DrawLine(p2, 280, 70, 500, 70)' Destroy custom Pen objects.p1.Dispose()p2.Dispose()gr.Dispose()
