parallel programming. this causual litery nots represents my recent progress in parallel programming in c#.It`s interesting.

namespace paraldemo

class Program
{
static void Main(string[] args)
{
var watch = Stopwatch.StartNew();
watch.Start();
var a = 2;
var c = 0;
String[] names = new string[] { "a", "b" };
Parallel.ForEach(names, d => { Console.Write("paraeel:" + d); });
Parallel.For(1, 4, b => { c += b; });
Parallel.Invoke(() => { Console.WriteLine(1); }, () => Console.WriteLine(2));
Console.WriteLine(c);
watch.Stop();
Console.WriteLine(watch.ElapsedMilliseconds);
var task1 = Task.Factory.StartNew(() => { Console.WriteLine("test task factory"); });
task1.Wait(2000);
var task2 = Task.Factory.StartNew(e => Console.WriteLine("2" + e), c);
Task.WaitAll(task1, task2);
Parallel.Invoke(() => Console.WriteLine(1));
Task.Factory.StartNew(() => Console.WriteLine(2), new CancellationTokenSource().Token);
Console.ReadKey();
}
}
