PowerShell - 使用另一個腳本文件的param調用和執行函數

Question

我無法從其他文件加載並執行函數。現在函數使用一個「虛擬」字符串變量，在主腳本中給出一個值（所以函數本身中的參數只是一個空的佔位符字符串，在主腳本中給出了值。

主腳本：下面的代碼之後更遍歷實例（$ InstanceList）的列表，併爲每個$例如，它會嘗試連接，然後應與參數$實例

#Loads Server Management Libraries 
    [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | Out-Null 
    [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.Management.RegisteredServers') | Out-Null 

    #Adds SQL Snapins 
    Add-PSSnapin SqlServerCmdletSnapin100 
    Add-PSSnapin SqlServerProviderSnapin100 

    #Loads CMS Function File 
    . .C:\Scripts\CMS_Functions\Environment_Functions.ps1; 

    #Variable for CMS Instance 
    $CMSInstance = 'CMSInstanceName'; 

    #Variable for the list of sql instances and their path 
    $InstanceList = Get-Content "C:\Scripts\InPutFiles\instancestest.txt"; 

    foreach($instance in $InstanceList) 
    {    
     #Creates a Server Management Object for the given $instance 
     $instanceObject = New-Object Microsoft.SqlServer.Management.Smo.Server($instance) 

     #Obtains the name of the instance from the sql server object 
     $InstanceName = $instanceObject.Name 

     #Connects to the Central Management Registered Server Instance 
     $connectionString = "Data Source=$CMSInstance;Initial Catalog=master;Integrated Security=SSPI;" 
     $sqlConnection = New-Object System.Data.SqlClient.SqlConnection($connectionString) 
     $conn = New-Object System.Data.SqlClient.SqlConnection("Server=$CMSInstance;Database=master;Integrated Security=True") 
     $CMSStore = New-Object Microsoft.SqlServer.Management.RegisteredServers.RegisteredServersStore($conn) 

    #Call Function 
     getProdInstances $InstanceName 
    } 

執行函數

功能腳本它基本上查詢一個sql表並找到實例，然後如果這些$ ins tances等於$ prodQuery數組中的第一條記錄，然後它補充說，例如一組在中央管理服務器（SQL的東西）（$實例是虛擬佔位符PARAM）

function getProdInstances $instance 
{ 
    $prodQuery = "SELECT DISTINCT INSTANCE 
       FROM TABLE where INSTANCE = '$instance' 
       ORDER BY INSTANCE;" 

    $prodQuery = Invoke-Sqlcmd -Query $prodQuery; 
    $prodResult = $prodQuery[0] 

    if($prodResult -eq $instance) 
    { 
     #Variable for the highest level group directory 
     $CMSDBStore = $CMSStore.ServerGroups["DatabaseEngineServerGroup"].ServerGroups["By Environment"].ServerGroups["PROD"] 

     #Sets the Registered Server Variables 
     $RegServerName = $prodResult 
     $RegServerInstance = $RegServerName 

     #Creates a Server Management Object for the Registered Server Group and Instance to be added to it 
     $NewServer = New-Object Microsoft.SqlServer.Management.RegisteredServers.RegisteredServer($CMSDBStore, "$RegServerName") 

     #Creates a secure connection to the Registered Server Instance 
     $NewServer.SecureConnectionString = "server=$RegServerInstance;integrated security=true" 
     $NewServer.ConnectionString = "server=$RegServerInstance;integrated security=true" 
     $NewServer.ServerName = "$RegServerInstance" 

     #Displays information to the command prompt that the instanec $RegServerName has been added to the $CMSInstance 
     Write-Host -ForegroundColor DarkGreen "Adding $RegServerName to $CMSInstance"; 

     #Adds the instance to the Registered Server CMS 
     $NewServer.Create() 
    } 

我得到的錯誤「getProdInstances」不被識別爲cmdlet的名稱，函數，等等等等等等。指向我稱之爲主腳本的行。我知道PS通過自上而下逐行執行，所以我不知道它是我設置主腳本的方式，還是如何設置函數。

對不起，我評論，而不是回答，所以你可能已經看到了刪除評論。

加載該函數的行不應該在末尾需要該分號，並且它不應該在路徑之前立即存在該句點。嘗試：

. C:\Scripts\CMS_Functions\Environment_Functions.ps1 

看看是否不會爲您加載函數，並解決問題。或者只是在腳本的開頭放置這個函數，而不是將它分解到它自己的文件中以避免所有問題。
