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$false,则会跳过该脚本块。 在上面的示例中,if语句仅计算$condition变量。 其计算结果为$true,将在脚本块内执行Write-Output命令。 在某些语言中,可以在if语句后放置一行代码,它将会得以执行。 在 PowerSh...

Tracepoints allow you to emit information to the Debug Console (or change state in your script) without ever pausing the debugger. These are effectively the same as using Set-PSBreakpoint -Action {scriptblock} where the scriptblock tests for a certain condition, and if met, executes some scr...
This may seem obvious, but the order in which multilevelIfconditions are checked can have an impact on a script’s speed. This is based on how many condition checks you have and which condition is likely to occur the most often. Windows PowerShell will stop checking the remaining conditions...
It is always a best practice when using the Switch statement to create a default action. If the script is not running with the –debug switch, the script will print out the value of the $action variable and tell the user to use either Start or Stop. If it is running with the debug ...
