A Do-While loop is a variety of the while loop. In a Do-While loop, 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 a Do-While loop, a Do-Until loop always runs at leas...
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;$i++){ >> Write-...
Do..While 构造运行脚本块,直到指定条件不为 true。 此构造保证脚本块至少运行一次。 Do..While 构造使用以下语法: PowerShell 复制 Do { Write-Host "Script block to process" } While ($answer -eq "go") Do..Until Do..Until 构造运行脚本块,直到指定条件为 true。 此构造保证脚本块至少...
