実際には PS 6+ では呼び出しがなくなりました。ドキュメントのよう-CompilerParameters
に置き換えられ、-CompilerOptions
文字列パラメーターが必要です。
次のように直接呼び出す必要があります
Add-Type -CompilerOptions "/unsafe" -TypeDefinition
ここから来ている場合function New-IsoFile
は、完全なコードです
function New-IsoFile
{
[CmdletBinding(DefaultParameterSetName='Source')]Param(
[parameter(Position=1,Mandatory=$true,ValueFromPipeline=$true, ParameterSetName='Source')]$Source,
