==Add point and size and copy to point==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Size sz = new Size(12, 12);
Point pt = new Point(20, 20);
pt = pt+sz;
MessageBox.Show("Addition :"+ pt.ToString());
pt = pt-sz;
MessageBox.Show("Subtraction :"+ pt.ToString());
PointF ptf = pt;
MessageBox.Show("PointF :"+ pt.ToString());
sz = (Size)pt;
MessageBox.Show("Size :"+ sz.Width.ToString()
+","+ sz.Height.ToString() );
}
}</source>

==Concert Point to Size==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Size sz = new Size(12, 12);
Point pt = new Point(20, 20);
pt = pt+sz;
MessageBox.Show("Addition :"+ pt.ToString());
pt = pt-sz;
MessageBox.Show("Subtraction :"+ pt.ToString());
PointF ptf = pt;
MessageBox.Show("PointF :"+ pt.ToString());
sz = (Size)pt;
MessageBox.Show("Size :"+ sz.Width.ToString()
+","+ sz.Height.ToString() );
}
}</source>

==Create and offset a point==

<source lang="csharp">using System;
using System.Drawing;
class MainClass
{
public static int Main(string[] args)
{

Point pt = new Point(100, 72);
Console.WriteLine(pt);
pt.Offset(20, 20);
Console.WriteLine(pt);

return 0;
}
}</source>
<pre class=codeResult>{X=100,Y=72}
{X=120,Y=92}</pre>

==Create a PointF from Point==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Size sz = new Size(12, 12);
Point pt = new Point(20, 20);
pt = pt+sz;
MessageBox.Show("Addition :"+ pt.ToString());
pt = pt-sz;
MessageBox.Show("Subtraction :"+ pt.ToString());
PointF ptf = pt;
MessageBox.Show("PointF :"+ pt.ToString());
sz = (Size)pt;
MessageBox.Show("Size :"+ sz.Width.ToString()
+","+ sz.Height.ToString() );
}
}</source>

==Createing Point==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Form form = new Form();
form.BackColor = Color.White;
form.Paint += new PaintEventHandler(MyPaintHandler);

Application.Run(form);
}

Graphics g = pea.Graphics;

Point pt = new Point(50, 50);
Point newPoint = Point.Empty;
newPoint.X = 100;
newPoint.Y = 200;
Pen pn = new Pen(Color.Blue, 4);
g.DrawLine(pn, pt, newPoint);
pn.Dispose();
g.Dispose();
}
}</source>

==Createing PointF==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Form form = new Form();
form.BackColor = Color.White;

newPoint.Y = 200.0F;
Pen pn = new Pen(Color.Blue, 4);
g.DrawLine(pn, pt, newPoint);
pn.Dispose();
g.Dispose();

}
}</source>

==Overloaded Point operators: ====

<source lang="csharp">using System;
using System.Drawing;
class MainClass
{
public static int Main(string[] args)
{

Point pt = new Point(100, 72);
Console.WriteLine(pt);
Point pt2 = pt;
if(pt == pt2)
Console.WriteLine("Points are the same");
else
Console.WriteLine("Different points");

return 0;
}
}</source>
<pre class=codeResult>{X=100,Y=72}
Points are the same</pre>

==Point Ceiling, Round, Truncate==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{

PointF pt1 = new PointF(30.6f, 30.8f);
PointF pt2 = new PointF(50.3f, 60.7f);
PointF pt3 = new PointF(110.3f, 80.5f);
Point pt4 = Point.Ceiling(pt1);
Point pt5 = Point.Round(pt2);
Point pt6 = Point.Truncate(pt3);
MessageBox.Show("Value of pt4: " +pt4.ToString());
MessageBox.Show("Value of pt5: " +pt5.ToString());
MessageBox.Show("Value of pt6: " +pt6.ToString());

}
}</source>

==Subtract point and size==

<source lang="csharp">using System;
using System.Drawing;
using System.Windows.Forms;
class PaintHello
{
public static void Main()
{
Size sz = new Size(12, 12);
Point pt = new Point(20, 20);
pt = pt+sz;
MessageBox.Show("Addition :"+ pt.ToString());
pt = pt-sz;
MessageBox.Show("Subtraction :"+ pt.ToString());
PointF ptf = pt;
MessageBox.Show("PointF :"+ pt.ToString());
sz = (Size)pt;
MessageBox.Show("Size :"+ sz.Width.ToString() +","+ sz.Height.ToString() );
}
}</source>
