Question

我发誓我已经看到了一个示例，说明如何“导入”.ps1（是的，故意不是.ps m 1）文件的内容。我的目标是在$变量中封装.ps1文件的内容，其中函数甚至可以在函数外部声明变量。所以，如果我有以下内容：

# ps1 file
Function myFunc {

  [CmdletBinding()]
  Param(...)

  # Function stuff

}

我想做这样的事情：

$newObject = New-Object (New-Module -ScriptBlock (%GET_CONTENT_FROM_PS1_FILE%))
$newObject.myFunc()
# etc.

这可能吗？

如PetSerAl's comment中精彩的例子，你已经走上了正确的道路：

耶！问题是，这只导出函数，而不是任何变量。

您可以做的是将PS> $newObject=New-Module -ScriptBlock (Get-Command .\Test.ps1).ScriptBlock -AsCustomObject PS> $newObject.myFunc Script : OverloadDefinitions : {System.Object myFunc();} MemberType : ScriptMethod TypeNameOfValue : System.Object Value : System.Object myFunc(); Name : myFunc IsInstance : True添加到ScriptBlock参数：

Export-ModuleMember

现在，变量$ps1ScriptBlock = Get-Content .\Test.ps1 -Raw $exportCommand = 'Export-ModuleMember -Function * -Variable *' $moduleScriptBlock = [scriptblock]::Create(@($ps1ScriptBlock,$exportCommand) -join "`r`n") $moduleObject = New-Module -ScriptBlock $moduleScriptBlock -AsCustomObject将可以访问：

$myVar

从ps1文件
