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...
PowerShell While 循环可以与break 和 continue 语句结合使用以进一步控制流程。让我们看看它们是如何工作的：代码 $counter = 1 while ($counter -le 5) { if ($counter -eq 3) { Write-Host "Skipping 3..." $counter++ continue } if ($counter -eq 5) { Write-Host "Breaking the loop at 5." ...
这种形式的循环出即for…loop结构,其一般格式如下: for(<initializer>;<exit condition>;<step action>) { <action> } 这种循环通过初始化计数器,每次循环的过程中递增或者递减该计数器,直到计数器达到退出要求。下例使用for循环重写前一节的while循环: PS C:\> for($i=0;$i -lt 3;$i++){ >> Write-...
The while statement (also known as a while loop) is a language construct for creating a loop that runs commands in a command block as long as a conditional test evaluates to true. The while statement is easier to construct than a for statement because its syntax is less complicated. In ad...
while(<condition>) 2. for循环 for(<initializer>;<exit condition>;<step action>) { <action> } 初始化和步进值为可选 3. 遍历集合的循环语句 for each Loop foreach($item in $collection) { <action> } 4. 强制退出循环使用break语句;反复遍历一个集合并操作其中的大多数对象,可以使用continue语句。
PowerShell：循环语句 1. 简单循环语句while while(<condition>){ <action block> } do { <action block> } while(<condition>)2. for循环 for(<initializer>;<exit condition>;<step action>){ <action> } 初始化和步进值为可选 3. 遍历集合的循环语句 for each Loop foreach($item in $collection){...
"While loop: " + $i $i ++ } "程式結束" ‧Do While Do While 迴圈的使用語法如下: Do { <程式碼區塊> } While (<條件式>) Do While 和 While 迴圈幾乎相同,差別只在 Do While 會先執行所屬的程式碼區塊,再檢查 <條件式>,若條件式成立會再次執行所屬的程式碼區塊,然後再檢查條件式,並以此...
try{$reader= [System.IO.StreamReader]::new($path)while(-not$reader.EndOfStream) {$line=$reader.ReadLine()if($line.Length-gt10) {$line} } }finally{if($reader) {$reader.Dispose() } } 也可以使用[System.IO.File]的ReadLines方法,它包装了StreamReader,简化了读取过程: ...
PowerShell默认情况是,当您在PowerShell控制台内单击时,PowerShell进入“选择模式”并暂停脚本,直到您单击空格、输入或转义。我有一个具有无限循环while ($true) {}的脚本,应该始终运行,当有人意外地单击PowerShell窗口时,我如何告诉PowerShell不要停止脚本呢?
[int]$range2 = Read-Host "Enter the last limit"; <#The for loop is setting the range of numbers#> for ($i = $range1; $i -le $range2; $i++) { $temp = $i; $originalnumber = $i; $revnum = 0; <#The while loop is to check the reverse of each number #> while ($temp...
