Improving Regular Expression Performance with Source Generators

Explore how to boost regular expression performance in C# using .NET 7 source generators. Learn to implement the [GeneratedRegex] attribute and partial methods that precompile regex logic, reducing runtime overhead while maintaining functionality. This lesson helps you understand compiler behavior and how to leverage modern .NET features to write more efficient and maintainable regex code.

When we pass a string literal or string constant to the constructor of Regex, the class parses the string and transforms it into an internal tree structure that represents the expression in an optimized way that can be executed efficiently by a regular expression interpreter.
