- Introduction
- Regular expressions describe patterns for matching in strings
- Regular expressions make code less verbose than traditional string methods
- Regex Methods
- Regex.IsMatch() checks if pattern matches string
- Regex.Match() returns first match as Match object
- Regex.Matches() returns collection of all matches
- Performance Considerations
- Regex object methods offer better performance for multiple matches
- Static methods are more concise for one-time matching
- Regex object compiles patterns internally for faster matching
- Implementation
- Requires System.Text.RegularExpressions namespace
- Pattern must be passed to Regex constructor
- IsMatch() method returns true for matches, false otherwise
