Regular Expression Basics C# Book

Regex.Split method is more powerful version of string.Split method.
In this example, we split a string, where any digit counts as a separator:
using System;
using System.Text.RegularExpressions;
class Program
{
static void Main(string[] args)
{
foreach (string s in Regex.Split ("a1b1c", @"\d"))
Console.Write (s + " ");
}
}
The output:
a b c
The following splits a camel-case string into separate words:
using System;
using System.Text.RegularExpressions;
class Program
{
static void Main(string[] args)
{
foreach (string s in Regex.Split ("oneTwoThree", @"(?=[A-Z])"))
Console.Write (s + " ");
}
}
The output:
one Two Three
