==Search an array using foreach.==

<source lang="csharp">using System;

class MainClass {
public static void Main() {
int[] nums = new int[10];
int val;
bool found = false;

for(int i = 0; i < 10; i++)
nums[i] = i;

val = 5;

foreach(int x in nums) {
if(x == val) {
found = true;
break;
}
}

if(found)
Console.WriteLine("Value found!");
}
}</source>
<pre class=codeResult>Value found!</pre>

==Use foreach on a two-dimensional array.==

<source lang="csharp">using System;

class MainClass {
public static void Main() {
int sum = 0;
int[,] nums = new int[3,5];

for(int i = 0; i < 3; i++)
for(int j=0; j < 5; j++)
nums[i,j] = (i+1)*(j+1);

foreach(int x in nums) {
Console.WriteLine("Value is: " + x);
sum += x;
}
Console.WriteLine("Summation: " + sum);
}
}</source>
<pre class=codeResult>Value is: 1
Value is: 2
Value is: 3
Value is: 4
Value is: 5
Value is: 2
Value is: 4
Value is: 6
Value is: 8
Value is: 10
Value is: 3
Value is: 6
Value is: 9
Value is: 12
Value is: 15
Summation: 90</pre>

==Use the foreach loop.==

<p>The foreach loop is used to cycle through the elements of a collection.</p>
<p>The general form of foreach is shown here:</p>

<source lang="csharp">foreach(type var-name in collection)
statement;</source>
