嵌套循环是编程中的一个强大概念，涉及在另一个循环中使用一个循环。在 PowerShell 中，您可以利用嵌套的 While 循环来处理需要重复操作中的重复操作的复杂场景。让我们通过一个例子来说明这个概念：代码 $outerCounter = 1 while ($outerCounter -le 3) { Write-Host "Outer Loop Iteration: $outerCounter" $i...
代码语言:txt 复制 $counter = 1 $shouldExit = $false while ($counter -le 10 -and !$shouldExit) { Write-Host "Counter: $counter" if ($counter -eq 5) { $shouldExit = $true } $counter++ } 上述代码通过$shouldExit变量来控制是否跳出循环,当$counter等于5时,将$shouldExit设为真,结束循...
The while statement (also known as a while loop) is a language construct for creating a loop that runs commands in a command block as long as a conditional test evaluates to true. The while statement is easier to construct than a for statement because its syntax is less complicated. In ad...
} //End ForEach loop. } // End of If if script exists. // If script block exists, see if this line matches any // of the match patterns. else { int patternIndex = 0; while (patternIndex < patterns.Length) { if ((simpleMatch && wildcardPattern[patternIndex].IsMatch(line)...
这种用法的好处尤其体现在“错误发生在嵌套循环”的时候，我们不用每一层循环都加一个标志位，逐级退出...

ADo-Whileloop is a variety of theWhileloop. In aDo-Whileloop, the condition is evaluated after the script block has run. As in a While loop, the script block is repeated as long as the condition evaluates to true. Like aDo-Whileloop, aDo-Untilloop always runs at least once before the...
