Hi,
You can use like this
Regex re = new Regex(@"^(33.)(0|build)(.)(\d{3})+$");
if (re.IsMatch(value))
MessageBox.Show("Matched");
else
MessageBox.Show("Doesn't Matched");

Example -
Matched: 33.0.123,33.0.111,33.0.001,33.build.123,33.build.111,33.build.001

Let me know if you need more details

Try the following:

using System;
using System.Text.RegularExpressions;
using System.IO;

class Program
{
static void Main()
{
string text = File.ReadAllText("example2.txt");
string regExp = @"(?s)((\d{2}\.(\d|build)\.\d{3}).*?loading ""(.+?)"".*?loading ""(.+?)"")";
MatchCollection mc = Regex.Matches(text, regExp);

foreach(Match m in mc)
{
Console.WriteLine(m.Groups[2].Value);
Console.WriteLine(m.Groups[4].Value);
Console.WriteLine(m.Groups[5].Value);
Console.WriteLine();
}

Console.ReadKey();
}
}

The output should be:

33.0.123
apple\folder1\folder2
bat\folder3\folder4

33.build.002
apple\folder1\folder2
bat\folder3\folder4

33.0.122
apple\folder1\folder2
bat\folder3\folder4

33.0.121
apple\folder1\folder2
bat\folder3\folder4

loading "bat\folder3\folder4"
unloaded "cat\fold5\fold6"

33.0.122
loading "apple\folder1\folder2"
loading "bat\folder3\folder4"
unloaded "cat\fold5\fold6"

Try:

using System;
using System.Text.RegularExpressions;

class Test
{
static void Main()
{
string text = "33.0.123 / 33.build.001";
string regExp = @"^\d\d\.\d\.\d\d\d / \d\d\.build\.\d\d\d$";
bool isMatch = Regex.IsMatch(text, regExp);
Console.WriteLine(isMatch); // True
Console.ReadKey();
}
}
