FastColoredTextBox is a .NET text editor component with fast, customizable syntax highlighting. It supports regex-based styling, word wrap, find/replace, code folding, and multilevel undo/redo, and handles very large files.

Use cases

• embed a syntax-highlighted code editor in a .NET winforms app
• build a custom text editor with syntax highlighting in C#
• display and edit very large text files in .NET
• add find/replace and code folding to a .NET textbox
• colorize text based on regular expressions in a .NET control

When to choose

• you need a fast, embeddable syntax-highlighting editor control for .NET desktop apps
• you want regex-driven custom highlighting rules
• you must handle large files in an editor component

When to avoid

• you need a cross-platform editor outside Windows/.NET
• you want a full standalone IDE rather than an embeddable component
• you need a web-based editor
