Console.WriteLine("They are: ");
for(int i=0; i < args.Length; i++)
Console.WriteLine(args[i]);
}
}</source>
<pre class=codeResult>There are 0 command-line arguments.

==Iterate over command-line arguments and print them out==

<source lang="csharp">using System;
class MainClass
{
public static void Main(string[] args)

{
Console.Write("Please enter your name: ");
string userName = Console.ReadLine();
Console.Write("Please enter your age: ");
string userAge = Console.ReadLine();

Console.ForegroundColor = ConsoleColor.Yellow;
Console.WriteLine("Hello {0}! You are {1} years old.",userName, userAge);
Console.ForegroundColor = prevColor;
}
}</source>

<source lang="csharp">using System;

class Cipher {
public static int Main(string[] args) {

if(args.Length < 2) {
Console.WriteLine("Usage: encode/decode word1 [word2...wordN]");
return 1; // return failure code
}

// if args present, first arg must be encode or decode
if(args[0] != "encode" & args[0] != "decode") {
Console.WriteLine("First arg must be encode or decode.");
return 1; // return failure code
}

for(int n=1; n < args.Length; n++) {
for(int i=0; i < args[n].Length; i++) {
if(args[0] == "encode")
Console.Write("encode");
else
Console.Write("Decode");
