C# - BREAK

Break as the name suggests, is used to break out of a loop(i.e. for loop) before its execution is complete.

To make it a little simpler, let us take the below example.

'Break' with 'for loop'

Say you have a for loop that is used to print the numbers from 1 to 5.

Example :

public class MyApplication
{
    public static void Main(string[] args)
    {
     	for(int x = 1; x <= 5 ; x++) 
     	{
          System.Console.WriteLine(x);
       	}
    }
}

Output :

1
2
3
4
5

But let us say, you want to break out of the for loop, if the value of x is 3. i.e. You want to get out of the loop, right after printing 1, 2 and 3.

And we can achieve it using break statement.

Let us modify the above program using the break statement.

Example :

public class MyApplication
{
    public static void Main(string[] args)
    {
     	for(int x = 1; x <= 5 ; x++) 
     	{
            System.Console.WriteLine(x);
      	    if (x == 3) {
 			    break;
 		    }
       	}
    }
}

Output :

1
2
3

And all we have done is placed an if condition, right after the print statement, checking if the value of x is equal to 3. If so we break out of the loop.

if (i == 3) {
	break;
}

And the break statement helps to get out of the for loop.
