How do I specify amount of threads I want to use?

[BataBo Jokviu]

So I want user to be able to specify how many threads my program should use,before I tried with maxdegree of parallelism but It only limited the amount of threads my program could use.Here is my code pls help:

class Program
{
static Regex idcheck = new Regex(@"id"":""(.+?)"",");
static Regex Migrationcheck = new Regex(@"legacy"".+?)}");





private static String _outputFileUnmigrated = "Unmigrated.txt";
private static String _outputFileMigrated = "Migrated.txt";
private static String _outputFileAvailable = "Available.txt";
private static String _outputValidationLog = "ValidationLog.txt";
private static String _outputUnmigratedGood = "UnmigratedGood.txt";
private static String _outputUnmigratedBad = "UnmigratedBad.txt";

static void Main(string[] args)
{
Console.Title = "Cookie Legacy checker | by BataBo | Checked: " + 0 + " | Good:" + 0;
