Below is a sample code snippet demonstrating the usage of RegexOptions.Compiled.
// Validating a Zip codes in C# using Regular Expression 2 string GKZipCode = @"^\d{5}(-?\d{4})?$"; 3 Regex regex = new Regex(GKZipCode, RegexOptions.Compiled); 4 bool Matching = regex.IsMatch("15689"); 5 Console.WriteLine(Matching); 6 Console.ReadLine();
