if陳述 以下是if語句的基本範例: PowerShell $condition=$trueif($condition) {Write-Output"The condition was true"} if語句所做的第一件事就是計算括號中的運算式。 如果計算結果為$true,則會在大括號中執行scriptblock。 如果值是$false,則會略過該腳本區塊。

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$false,则会跳过该脚本块。
<condition>如果 、<if-true>或<if-false>表达式调用命令,则必须将其括在括号中。 否则,PowerShell 会为 表达式中的<condition>命令引发参数异常,并分析 和<if-false>表达式的<if-true>异常。 例如,PowerShell 会为以下三元项引发异常: PowerShell
if($a -gt 1) {"$a 大于 1"} elseif ($a -lt 1){"$a 小于 1"} else {"1等于1"} 1. 2. 3. 4. SWITCH 条件判断语句: AI检测代码解析 #一般执行语法 $a=10 switch($a) { 1 {"return 1"} 2 {"return 2"} 3 {"return 3"} ...
PowerShell 中的 if 语句用于执行条件判断,当条件为 true 时,执行相应的命令或代码块。语法结构如下: if (condition) { # commands or script block } 其中,condition 是一个条件表达式,如果该表达式的值为 $true$ 则执行 commands or script block, 否则不执行. 例如, 下面这段代码检查变量 $x$ 是否大于 ...
If / elseif /else functionality PowerShell In the above examples, we have seen that if and else conditions are not satisfied if we have multiple if conditions, so it checks every If condition and when they are not true then else statement is executed. Here, to meet execution time criteria...
Also, by default Powershell already includes the Boolean variables $True and $False to represent True and False. You can use them in any session or script. Evan7191(Evan7191)July 17, 2017, 1:09pm9 Example: If (condition is true) ...
