C# Break and Continue


C# Break

You have already seen the break statement used in an earlier chapter of this tutorial. It was used to "jump out" of a switch statement.

The break statement can also be used to jump out of a loop.

This example jumps out of the loop when i is equal to 4:

Example

for (int i = 0; i < 10; i++) 
{
  if (i == 4) 
  {
    break;
  }
  Console.WriteLine(i);
}

C# Continue

The continue statement breaks one iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop.

This example skips the value of 4:

Example

for (int i = 0; i < 10; i++) 
{
  if (i == 4) 
  {
    continue;
  }
  Console.WriteLine(i);
}

Break and Continue in While Loop

You can also use break and continue in while loops:

Break Example

int i = 0;
while (i < 10) 
{
  Console.WriteLine(i);
  i++;
  if (i == 4) 
  {
    break;
  }
}

Continue Example

int i = 0;
while (i < 10) 
{
  if (i == 4) 
  {
    i++;
    continue;
  }
  Console.WriteLine(i);
  i++;
}
