Polygons are essential shapes in computer graphics, image processing, and game development, and C# provides a robust set of tools for drawing them. This guide will walk you through the process of creating and rendering different polygons in C#.
Draw Polygon in C#
You need to follow the steps below to draw a polygon in C#:
- Set up Conholdate.Total for .NET in your IDE.
- Instantiate a Bitmap class object.
- Initiate a Graphics class instance and a Pen while setting the width and color.
- Draw the polygon shape with DrawPolygon method while setting the points.
- Write the output image drawing using the Save method.
The following code snippet explains how to draw a polygon in C#:
The following image displays the polygon created with this sample code:
Draw Filled Polygon in C#
You can create filled polygons with any fill color or texture. The following steps explain how to draw a filled (solid) polygon in C#:
- Install Conholdate.Total for .NET on your end.
- Declare an object of Bitmap class.
- Create a Graphics class object and make a brush while setting the fill color.
- Draw a polygon shape with the FillPolygon method and specify the vertices.
- Render the output drawing with the Save method.
The following code snippet elaborates on how to draw a filled polygon in C#:
The screenshot below shows the filled polygon created with the above code:

Summing Up
Drawing polygons in C# is a fundamental skill for any graphics-related project. With the right tools and knowledge, you can create complex shapes and render them to achieve your desired visual effects. This guide has provided you with the basic steps to get started, but there’s so much more you can explore, such as filling polygons, applying textures, changing shapes, border color, fill color, etc. Experiment, practice, and you’ll be well on your way to creating impressive polygons in C#.

FAQs
What is a polygon in computer graphics?
A polygon is a closed shape with multiple sides or edges, often used in computer graphics to represent various objects. It can be a triangle, rectangle, hexagon, or any other shape with straight sides.
What is the difference between drawing a filled polygon and an unfilled one in C#?
Drawing a filled polygon means that the interior of the polygon is colored, creating a solid shape. Drawing an unfilled polygon only outlines the edges of the shape, leaving the interior empty.
Can I apply different colors to the interior or outline of a polygon in C#?
Yes, you can apply different colors to the interior (fill) or the outline (stroke) of a polygon. You can customize the colors using brushes for the fill and pens for the outline.
Can I draw different types of polygons in C#?
Yes, C# allows you to draw various types of polygons, such as triangles, rectangles, pentagons, and more. You can define the vertices and draw any polygon of your choice.
