如何使用 PowerShell 从 GAC 中已存在的给定路径中删除所有 dll?
How to delete all dlls from given path that already exist in the GAC using PowerShell?
这里是否有任何 PowerShell 专家知道如何从 GAC 中已存在的给定路径中删除所有 dll?
您可以通过名称确定程序集是否已在 GAC 中:
$AssemblyName = [System.Reflection.AssemblyName]::GetAssemblyName("C:\Path\to\assembly.dll")
$IsInGAC = [System.Reflection.Assembly]::ReflectionOnlyLoad($AssemblyName).GlobalAssemblyCache
您可以将其包装在测试函数中以过滤您的输入程序集:
function Test-GACPresence {
param(
[Parameter(Mandatory=$true,ParameterSetName='Path')]
[string]$Path,
[Parameter(Mandatory=$true,ParameterSetName='LiteralPath',ValueFromPipelineByPropertyName=$true)]
[Alias('PsPath')]
[string]$LiteralPath
)
$LiteralPath = if($PSCmdlet.ParameterSetName -eq 'Path'){
(Resolve-Path $Path).ProviderPath
} else {
(Resolve-Path $LiteralPath).ProviderPath
}
try{
return [System.Reflection.Assembly]::ReflectionOnlyLoad([System.Reflection.AssemblyName]::GetAssemblyName($LiteralPath)).GlobalAssemblyCache
}
catch{
return $false
}
}
$ExistsInGAC = Get-ChildItem "path\to\test" -Filter *.dll -Recurse |?{$_|Test-GACPresence}
$ExistsInGAC |Remove-Item
