如果<condition>表达式为 false,则执行<if-false>表达式 例如: PowerShell复制 $message= (Test-Path$path) ?"Path exists":"Path not found" 在此示例中,当 返回 时,$message的值为Path exists。Test-Path$true$false返回 时Test-Path,的$messagePath not found值为 。
if语句 下面是if语句的基本示例: PowerShell $condition=$trueif($condition) {Write-Output"The condition was true"} if语句执行的第一步是计算括号中的表达式。 如果计算结果为$true,则执行大括号中的scriptblock。 如果值为$false,则会跳过该脚本块。
