Paint Application in C# Using Visual Studio

Creating a Paint Application in C# Using Visual Studio

Building a simple Paint application in C# using Visual Studio is an excellent beginner project to understand graphics programming and event handling in Windows Forms. The application allows users to draw, erase, and color shapes using the mouse—similar to Microsoft Paint.

To begin, open Visual Studio and create a new Windows Forms App (.NET Framework) project. Use a PictureBox as the drawing canvas. The drawing logic can be implemented using the Graphics class in C#, which enables line, shape, and freehand drawing. By handling MouseDown, MouseMove, and MouseUp events, you can capture the mouse position and draw lines as the user drags the cursor.

Add features like color selection using the ColorDialog tool, brush size adjustment with a TrackBar, and an Eraser mode by changing the pen color to match the background. You can also include menu options like Save and Clear Canvas using standard file dialogs.

This project helps beginners learn about GDI+, object-oriented programming, and Windows event handling in a practical way. It is a fun and educational project that enhances creativity while strengthening programming fundamentals in C#.
