WorkingWithRegex - Regular Expressions Examples and Benchmarks in C#

Two-project solution demonstrating regular expressions in C#. The BasicRegexExamples project shows three regex patterns: starts-with (^Hello), ends-with (ing$), and numeric pattern matching ([0-9]+[a-zA-Z]*[0-9]+).

The RegexBenchmarks project uses BenchmarkDotNet to compare 8 different regex approaches: static Regex.Matches, new instance, compiled, cached, source-generated, and combinations thereof. Tests the pattern \b\w*(ing|ed)\b against a large text file. .NET 8, BenchmarkDotNet 0.13.12.
