Using a for loop gives more control over limits and conditions on when the code should exit. This is compared with the foreach loop or the ForEach-Object cmdlet, where iteration stops after the last item in the collection was processed. Below is the syntax of the for loop statement for ...
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;$i++){ >> Write-...
for(<initializer>;<exit condition>;<step action>) { <action> } 初始化和步进值为可选 3. 遍历集合的循环语句 for each Loop foreach($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。break所在的程序段的条件满足的情况...
$numList=1,2,3,4,5,6,7,8foreach($numberin$numList){if($number-eq8){#Terminate loop if number variable is equal to 8break}Write-Output$number} 输出: 1234567 如果我们有嵌套循环,我们只会从调用break命令的循环中中断。 示例代码: While($true) {While($true) {#The break command will onl...

✅ Powershell: I need to exit the Switch and Try and continue the Loop:I have a condition embedded in a Loop, Try, Switch and if the condition is met, I want to gracefully exit the Loop iteration and go onto the next Loop...
Current: one Current: two Reset Loop: 0 Current: one Current: two Reset Loop: 1 Current: one Current: two Current: three 範例5:使用 $switch 變數 變數$switch的規則與變數完全相同$foreach。 下列範例示範所有列舉值概念。 備註 請注意,NotEvaluated案例永遠不會執行,即使MoveNextbreak沒有語句也一樣。

Additionally, instead of using an explicit $loaded variable, I could have used the Windows PowerShell break statement to exit the delay loop. Windows PowerShell has a rich set of control structures that allow you to program in many different styles, including whatever programming style you are ...
