Introduction

This piece of code will convert our Windows form from this rectangular shape

to an elliptical shape like this.

Background

Once I was going through the properties of my form through MSDN. I just happened to come across region property of my form. Then I did something funny I tried to change the shape of my form.

Using the code

To accomplish this task I have used GraphicsPath class from using System.Drawing.Drawing2D namespace.

To change shape of my form initially I have to change my region of my form.

Form's region property accepts a value of Region class.

Region class accepts an object of GraphicsPath class.

So first I created an object of GraphicsPath class. Then I added an ellipse using my object of my GraphicsPath, gp. After that I create an object of Region which accepts a parameter of my GraphicsPath. Now I have to just pass my reg to my forms region property.

GraphicsPath gp = new GraphicsPath();
gp.AddEllipse(50, 50, 200, 100);
Region reg = new Region(gp);
this.Region = reg;
this.BackColor = Color.Maroon; 

You can try with different shapes in GraphicsPath. Now go ahead and try resizing forms as per your wish.

Happy resizing.
