Improving Regular Expression Performance with Source Generators

Improving Regular Expression Performance with Source Generators

Learn about optimizing regular expressions which allows for improved performance compared to compiling regular expressions.

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.

Optimizing regular expression performance with compilation

We can also compile regular expressions by specifying a RegexOption, as shown in the following code:

Regex ageChecker = new(digitsOnlyText, RegexOptions.Compiled);
