<source lang="csharp">using System;
class MainClass
{
public static int Main()
{

return(0);
}

<pre class=codeResult>Hello, Universe!</pre>

==The Main Function: use foreach to loop through command-line parameters==

<source lang="csharp">using System;
class MainClass
{
public static void Main(string[] args)
{
foreach (string arg in args)
Console.WriteLine("Arg: {0}", arg);
}

<source lang="csharp">using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
