.net - Powershell [System.IO.Compression.ZipArchiveEntry] 不包含名为 'ExtractToFile' 的方法

Question

我有一个 powershell 脚本，我想从中提取特定条目。我似乎无法弄清楚如何解决无法在 .NET ZipArchiveEntry 对象上找到扩展方法的错误。

下面我的脚本将运行并将“写出”zip 中的文件，但是当它到达 $entry.ExtractToFile($dst) 行时，它会产生以下错误:

Method invocation failed because [System.IO.Compression.ZipArchiveEntry] does not contain a method named 'ExtractToFile'.

Add-Type -AssemblyName System.IO.Compression -ErrorAction Stop
Add-Type -AssemblyName System.IO.Compression.FileSystem -ErrorAction Stop

$filesToExtract = @(
    "appsettings.json";
    "Content\cms\index.xml";
)
$archive = "C:\Users\User1\Desktop\archive.zip"
$dstRoot = "C:\Users\User1\Desktop\test"
$zip = [IO.Compression.ZipFile]::OpenRead($archive)
foreach($entry in $zip.Entries){
    if ($filesToExtract -contains $entry.FullName){
        $dst = [io.path]::combine($dstRoot, $entry.FullName)
        %{ "Extract ==> " + $dst }        

        $entry.ExtractToFile($dst)

    }
}
$zip.Dispose()

尝试使用 [System.IO.Compression.ZipFileExtensions]。如果提取文件已经存在，它将失败。

[cmdletbinding()]

Add-Type -AssemblyName System.IO.Compression.FileSystem -ErrorAction Stop

$filesToExtract = @(
    "t.txt";
)
$archive = "$PSScriptRoot\t.zip"
$dstRoot = "$PSScriptRoot"
$zip = [System.IO.Compression.ZipFile]::OpenRead($archive)

foreach($entry in $zip.Entries){
    if ($filesToExtract -contains $entry.FullName){
        $dst = [io.path]::combine($dstRoot, $entry.FullName)

        if (Test-Path -Path $dst) { Remove-Item -Path $dst }

        Write-Verbose $("Extract ==> {0}" -f @($dst))
        [System.IO.Compression.ZipFileExtensions]::ExtractToFile($entry, $dst)
    }
}
$zip.Dispose()
