Question

我有一个PowerShell脚本，我想提取特定的条目。我似乎无法弄清楚如何在.NET ZipArchiveEntry对象上找不到扩展方法的错误。

我的下面的脚本会运行，并且会写出＆＃34;写出＆＃34;来自zip的文件，但当它到达 $ entry.ExtractToFile（$ dst）行时，会产生以下错误：

方法调用失败，因为[System.IO.Compression.ZipArchiveEntry]不包含名为＆＃39; ExtractToFile＆＃39;的方法。

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()]
Param()

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()

Powershell [System.IO.Compression.ZipArchiveEntry]不包含名为＆＃39; ExtractToFile＆＃39;
