我写了这个Power
Shell脚本,该脚本应该在特定日期范围内对所有日志文件进行归档.
$currentDate = Get-Date;
$currentDate | Get-Member -Membertype Method Add;
$daysBefore = -1;
$archiveTillDate = $currentDate.AddDays($daysBefore);
$sourcePath = 'C:\LOGS';
$destPath='C:\LogArchieve\'+$archiveTillDate.Day+$archiveTillDate.Month+$archiveTillDate.Year+'.zip';
foreach( $item in (Get-ChildItem $sourcePath | Where-Object { $_.CreationTime -le $archiveTillDate }) )
{
[Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem");
$compressionLevel = [System.IO.Compression.CompressionLevel]::Optimal;
[System.IO.Compression.ZipFile]::CreateFromDirectory($sourcePath,$destPath,$compressionLevel,$false);
}
它工作直到foreach循环,但一旦循环它给出这些错误：
Unable to find type [System.IO.Compression.CompressionLevel]: make sure that the assembly containing this type is loaded. At line:4 char:65 + $compressionLevel = [System.IO.Compression.CompressionLevel] <<<< ::Optimal; + CategoryInfo : InvalidOperation: (System.IO.Compression.CompressionLevel:String) [],RuntimeException + FullyQualifiedErrorId : TypeNotFound
由于System.IO.Compression是.NET 4.5的一部分,我已经将其安装在系统上,但是我仍然收到这些错误.
我在Windows Server 2008 R2和PowerShell v2.0.
我该如何让它工作？
您可以手动将
.NET类添加到PowerShell会话.
原文链接：https://www.f2er.com/windows/371428.html删除[Reflection.Assembly] :: LoadWithPartialName(“System.IO.Compression.FileSystem”);从您的脚本,并添加以下在顶部：
Add-Type -Path "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.IO.Compression.FileSystem.dll"
或在一个32位盒子上：
Add-Type -Path "C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.IO.Compression.FileSystem.dll"
这假定您的系统上的.NET 4.5安装OK,System.IO.Compression.FileSystem.dll实际上存在.
