對於函式,這三種方法是由函式的 begin、 process和end 區塊表示。 PowerShell 7.3 新增區塊 clean 進程方法。 您不需要在函式中使用任何這些區塊。 如果您沒有使用具名區塊,PowerShell 會將程式代碼 end 放入函式的 區塊中。 不過,如果您使用這些具名區塊中的任何一個 dynamicparam ,或定義區塊,則必須將所有程式...
如果不在定义中使用其中一个关键字(begin、、process、endclean),PowerShell 会将语句放在块中end。function 有关函数中的 dynamicparam 关键字和动态参数的详细信息,请参阅 about_Functions_Advanced_Parameters。 函数可以像以下一样简单: PowerShell 复制 function Get-PowerShellProcess { Get-Process pwsh } 定...

Other restrictions such as the BEGIN, PROCESS, and END blocks that you can use in functions impact features that don’t really fit with the workflow concept. The other restriction that can have a big impact is that you can’t use inline comment-based Help. You have to use XML-based ...

在执行每个命令的每个实例之前,执行将停止。 如果命令是一个函数,则每次调用函数时,执行都会停止,每次调用该函数时,都会在每个begin、process和end块处停止。 类型:String[] 别名:C Position:Named 默认值:None 必需:True 接受管道输入:False 接受通配符:True ...
function <name> { BEGIN { # } PROCESS { # } END { # } } As you can see, this function contains three independent script blocks, named BEGIN, PROCESS, and END. A filtering function—that is, a function designed to work within the pipeline to filter objects—can have any combination ...

PowerShell executes the begin statement when it loads your script, the process statement for each item passed down the pipeline, and the end statement after all pipeline input has been processed. 3. 采用main函数的script语句 function Main
