Stop loops early with break. Usually each C# loop has an exit condition. A while loop, for instance, goes on until its condition tests true. Then when that condition is false, the loop ends. But we can also stop the loop earlier. For that we use C#’s break statement.
C# has several ways to exit a nested loop right away: The goto statement stops a nested loop easily, no matter how many loops inside each other we got. The return statement immediately ends a nested loop we got in a separate method.
The break statement is the most common way to end C# loops. This statement immediately ends the loop that executes it. But to exit from nested loops, we have to execute break several times. That isn’t the most practical. With the goto statement, on the other hand, we can immediately jump out of loops to a particular labelled statement. That ...
14 mar 2023 · The break statement terminates the closest enclosing iteration statement (that is, for, foreach, while, or do loop) or switch statement. The break statement transfers control to the statement that follows the terminated statement, if any.
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; } }
C# only allows you to use the break statement inside a loop (or a switch statement). This tutorial focuses on how to use the break statement inside a loop. In practice, you’ll use the break statement to terminate a loop based on a condition prematurely.
