If you want the regular expression to run faster , you can set the RegexOptions.Compiled value to the regex constructor. This will compile the regex in to their own assembly which will run a little faster.
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();
