This is not a complete answer to your question; however, I've included some code that is 1/2 your answer

I'm guessing you'll want to set a dash pattern on your pen (DashPattern). You set this to an array of floats that gives the widths of the dashes and spaces.

Create dash pattern:

float[] dashValues = {3, 1, 3, 1, 3, 1, 3, 1};

Set dash pattern on your pen

myPen.DashPattern = dashValues;

Set DashStyle to custom

myPen.DashStyle = DashStyle.Custom;

Draw your line.

The following code can be placed in a C# application with a button called btnGo.

private void btnGo_Click(object sender, System.EventArgs e)
{
   Graphics g = this.CreateGraphics();
   g.Clear(this.BackColor);

   // Create pen
   Pen myPen = new Pen(Color.Blue, 3);

   // Following uses standard styles:

   myPen.DashStyle = DashStyle.Dash;
   myPen.DashOffset = 40;
   myPen.DashCap = DashCap.Triangle;
   g.DrawLine (myPen, 10, 10, (Form1.ActiveForm.Width - 10), 10);
   myPen.DashStyle = DashStyle.DashDot;
   g.DrawLine(myPen, 10, 30, (Form1.ActiveForm.Width - 10), 30);
   myPen.DashStyle = DashStyle.Dot;
   g.DrawLine(myPen, 10, 50, (Form1.ActiveForm.Width - 10), 50);
   myPen.DashStyle = DashStyle.Dash;
   g.DrawLine(myPen, 10, 70, (Form1.ActiveForm.Width - 10), 70);
   myPen.DashStyle = DashStyle.DashDotDot;
   g.DrawLine(myPen, 10, 90, (Form1.ActiveForm.Width - 10), 90);
   myPen.DashStyle = DashStyle.Custom;
   g.DrawLine(myPen, 10, 110, (Form1.ActiveForm.Width - 10), 110);

   // custom
   // pen width...
   int myPenWidth = 2;
   myPen.Color = Color.Green;
   myPen.Width = myPenWidth;
   // set a float array to widths you want custom dashes...
   // first value draw width, second space, third draw, etc.
   float[] dashValues = {myPenWidth*2, myPenWidth, myPenWidth*2, myPenWidth,
               myPenWidth*2, myPenWidth, myPenWidth*2, myPenWidth };
   // set dash pattern on your pen
   myPen.DashPattern = dashValues;
   // set DashStyle to custom
   myPen.DashStyle = DashStyle.Custom;
   g.DrawLine(myPen, 10, 130, (Form1.ActiveForm.Width - 10), 130);
	
   // Displose
   myPen.Dispose();
   g.Dispose();
}

Don't know if this helps, or if is stuff you knew.

But the vertical line not draw in the dash line.



----|----|----|----
or
