How to use

using System;
using Kaz.Operations.Text.RegularExpressions;

class Program
{
    static void Main(string[] args)
    {
        var builder = new RegexBuilder();

        builder
            .Start() // Start anchor
            .Charset(() => new RegexCharset()
                .AddRange('a', 'z')
                .AddRange('A', 'Z')
                .AddRange('0', '9')
                .AddWord("._%+-")
            ).OneOrMore() // Quantifier

            .Literal("@")

            .Charset(() => new RegexCharset()
                .AddRange('a', 'z')
                .AddRange('A', 'Z')
                .AddRange('0', '9')
                .AddWord(".-")
            ).OneOrMore() // Quantifier

            .Literal(".")

            .Charset(() => new RegexCharset()
                .AddRange('a', 'z')
                .AddRange('A', 'Z')
            ).Repeat(2, 6) // Quantifier

            .End(); // End anchor

        var emailRegex = builder.Build(); // returns a new Regex instance

        string testEmail = "bronsk1y@gmail.com";
        bool isValid = emailRegex.IsMatch(testEmail); // true
    }
}
