==An Action triggered by Array.ForEach==

<source lang="csharp">using System;

class MyClass {
public int i;

public MyClass(int x) {
i = x;
}
}

class MainClass {

static void show(MyClass o) {
Console.Write(o.i + " ");
}

public static void Main() {
MyClass[] nums = new MyClass[5];

nums[0] = new MyClass(5);
nums[1] = new MyClass(2);
nums[2] = new MyClass(3);
nums[3] = new MyClass(4);
nums[4] = new MyClass(1);

Console.Write("Contents of nums: ");

// Use action to show the values.
Array.ForEach(nums, MainClass.show);

Console.WriteLine();

}
}</source>
<pre class=codeResult>Contents of nums: 5 2 3 4 1</pre>

==Array.ForEach with a delegate==

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

public class MainClass
{
public static void Main()
{
int[] array = new int[] { 8, 2, 3, 5, 1, 3 };
Array.ForEach<int>(array, delegate(int x) { Console.Write(x + " "); });
Console.WriteLine();
}
}</source>
<pre class=codeResult>8 2 3 5 1 3</pre>

==foreach with Arrays==

<source lang="csharp">class MainClass
{
static void Main()
{
int[] array = new int[]{1, 2, 3, 4, 5, 6};

foreach (int item in array)
{
System.Console.WriteLine(item);
}
}
}</source>

==Use an Action to change the values==

<source lang="csharp">using System;

class MyClass {
public int i;

public MyClass(int x) {
i = x;
}
}

class MainClass {

static void neg(MyClass o) {
o.i = -o.i;
}

public static void Main() {
MyClass[] nums = new MyClass[5];

nums[0] = new MyClass(5);
nums[1] = new MyClass(2);
nums[2] = new MyClass(3);
nums[3] = new MyClass(4);
nums[4] = new MyClass(1);

// Use action to negate the values.
Array.ForEach(nums, MainClass.neg);

}
}</source>
