帶參數*和*函數的Powershell腳本

Question

我想編寫一個接受參數並使用函數的powershell腳本。

我嘗試這樣做：

param 
(
    $arg 
) 

Func $arg; 


function Func($arg) 
{ 
    Write-Output $arg; 
} 

，但我得到這個：

The term 'Func' is not recognized as the name 
of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, 
verify that the path is correct and try again. 
At func.ps1:6 char:5 
+ Func <<<< $arg; 
    + CategoryInfo   : ObjectNotFound: (Func:String) [], CommandNotFoundException 
    + FullyQualifiedErrorId : CommandNotFoundException 

很好，我想。我會代替試試這個：

function Func($arg) 
{ 
    Write-Output $arg; 
} 


param 
(
    $arg 
) 

Func $arg; 

但後來，我得到這個：

The term 'param' is not recognized as the name 
of a cmdlet, function, script file, or operable program. 
Check the spelling of the name, or if a path was included, 
verify that the path is correct and try again. 
At C:\Users\akina\Documents\Work\ADDC\func.ps1:7 char:10 
+  param <<<< 
    + CategoryInfo   : ObjectNotFound: (param:String) [], CommandNotFoundException 
    + FullyQualifiedErrorId : CommandNotFoundException 

就是我要求的可行？或者我的要求不合理？

Answer 1

腳本中的參數塊必須是第一個非註釋代碼。在此之後，你需要定義函數調用之前，例如： -

param 
(
    $arg 
) 

function Func($arg) 
{ 
    $arg 
} 

Func $arg 

寫產出是你的榜樣不必要的，因爲默認的行爲是輸出對象到輸出流。

Answer 2

你可以把param標籤裏面的功能..

事情是這樣的：

function func($avg) 
{ 
    param 
    (
     $avg 
    ) 
}

所有你需要學聯確保參數是腳本的第一個字符串。
