Like a Do-While loop, a Do-Until loop always runs at least once before the condition is evaluated. However, the script block runs only while the condition is false. The continue and break flow control keywords can be used in a Do-While loop or in a Do-Until loop. Syntax The following...
Den första metoden är en specifik parametersyntax som kan användas för alla parametrar, men du ser oftast att den används för växelparametrar. Du anger ett kolon för att koppla ett värde till parametern.PowerShell Kopiera ...
This syntax breaks down as follows: $_ 表示通过管道的当前对象。 。Id 指定哪个特定属性值与操作相关联。 -ErrorAction -SilentlyContinue 用于忽略 Get-NetTCPConnection CmdLet 期间可能出现的任何错误。例如,如果进程 ID 未链接到指定的 TCPConnection,CmdLet 将引发异常。该参数允许忽略这些异常。 Format-Table -...

不带标签的 continue 语句会立即将程序流返回到由 for、foreach、do 或while 语句控制的最内层循环的顶部。 循环的当前迭代将终止,循环将继续进行下一次迭代。 在下面的示例中,如果 $ctr 变量等于 5,程序流将返回到 while 循环的顶部。 因此,除了 5 之外,将显示介于 1 和 10 之间的所有数字...

suppress the expanding nature of the expanding string for the first$ivariable so that we can see which variable we are talking about. As soon as we have done this, we increment the value of the$ivariable by one. To do this, we use the$i++syntax. This is identical to saying the ...
