Powershell3.0_4.0解压zip

当你安装了.Net4.5及以后版本，你可以这样尝试解压缩：

#requires -Version 2
# .NET Framework 4.5 required!

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

$Source = 'C:\somezipfile.zip'
$Destination = 'C:\somefolder'
$Overwrite = $true
$ShowDestinationFolder = $true

if ((Test-Path $Destination) -eq $false) 
{
 $null = mkdir $Destination 
}

$Content = [IO.Compression.ZipFile]::OpenRead($Source).Entries
$Content | 
 ForEach-Object -Process {
    $FilePath = Join-Path -Path $Destination -ChildPath $_
                [IO.Compression.ZipFileExtensions]::ExtractToFile($_,$FilePath,$Overwrite)
            }
if ($ShowDestinationFolder) 
{
 explorer.exe $Destination 
}
