Parallel Tasks in .NET 4.0

In .NET 4.0, we have a set of new API's to simplify the process of adding parallelism and concurrency to applications. This set of API's is called the "Task Parallel Library (TPL)" and is located in the System.Threading and System.Threading.Tasks namespaces.

For Example:
using System.Threading;
using System.Threading.Tasks;

public partial class ParallelInvoke : System.Web.UI.Page
{
static string stValues = string.Empty;

protected void Page_Load(object sender, EventArgs e)
{
stValues = "";
Parallel.Invoke(new Action(GenerateNumbers), new Action(PrintCharacters), new Action(PrintArray));
parallelInvokelbl.Text = stValues;
}

static void GenerateNumbers()
{
for (int i = 0; i < 10; i++)
{
stValues += "Method1 - Number " + i.ToString() + "
";
Thread.Sleep(1000);
}
}

static void PrintCharacters()
{
string str = "blog";
for (int i = 0; i < str.Length; i++)
{
stValues += "Method2 - Character " + str[i].ToString() + "
";
Thread.Sleep(1000);
}

}

static void PrintArray()
{
int[] arr = { 1, 2, 3, 4, 5, 6, 7, 8 };
foreach (int i in arr)
{
stValues += "Method3 - Array " + i.ToString() + "
";
Thread.Sleep(1000);
}
}
}
