Question about GDI+. Thanks.

How to draw a style line(bezier,polyline etc.) as:

----|----|----|----|----|----|----


Thanks.

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.

Code:

---

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.
