Windows Powershell中的io.compression.zipfile异常

我正在使用powershell脚本自动归档目录及其子目录。我用的是一个非常简单的

    Add-Type -AssemblyName "system.io.compression.filesystem"
    [io.compression.zipfile]::CreateFromDirectory($d, $destinationFilename)

在很大程度上，这正是我需要它做的；但是最近出现了空子目录的问题。这些空子目录以某种方式被压缩为文件，而不是目录

首先，还有其他人遇到过这种情况吗

问题是否与此.NETAPI有关，或者是否存在环境问题

我应该使用不同版本的：：CreateFromDirectory函数吗

谢谢你的帮助

我正在使用Bryan的脚本，它做到了它所说的，并且也应该满足您的要求

有很多参数可以使用，比如压缩类型、时间戳、确认

# Purpose: Creates a .zip file of a file or folder.
#
# Sample: zipstuff.ps1 -target "C:\Projects\wsubi" -zip_to "C:\Users\Bryan\Desktop\wsubi" [-compression fast] [-timestamp] [-confirm]
#
# Params:
# -target: The file or folder you would like to zip.
#
# -zip_to: The location where the zip file will be created. If an old version
# exists, it will be deleted.
#
# -compression (optional): Sets the compression level for your zip file. Options:
# a. fast - Higher process speed, larger file size (default option).
# b. small - Slower process speed, smaller file size.
# c. none - Fastest process speed, largest file size.
#
# -add_timestamp (optional): Applies a timestamp to the .zip file name.
# By default, no timestamp is used.
#
# -confirm (optional): When provided, indicates that you would like to be
# prompted when the zip process is finished.

用法：

zipstuff.ps1 -target "C:\Projects\wsubi" -zip_to "C:\Users\Bryan\Desktop\wsubi" [-compression fast] [-timestamp] [-confirm]

希望有帮助。

考虑过了吗？我很乐意尝试一下。谢谢它使用的不是.Net framework库吗？您能描述一下发生这种情况的示例目录结构吗？似乎无法复制添加为文件的目录有什么特殊之处吗？是否仅在压缩网络共享上的文件时使用？是否只有名称中包含特定字符的文件？是否仅当您从特定服务器运行脚本时？您是否尝试过指定程序集的全名（例如，

Add Type-AssemblyName'System.IO.Compression.FileSystem，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089'

）？大家好，目录结构是一个专用的额外驱动器；但它不是一种共享资源。结构很深，但并不复杂。D:\Parent\…，其中空目录位于父目录下两层或两层以上的位置。空目录所在的位置没有特定的模式。注意，在某些情况下，即使目录是空的，它们也是必需的。没有它们会干扰其他流程。考虑过了吗？我很乐意尝试一下。谢谢它使用的不是.Net framework库吗？您能描述一下发生这种情况的示例目录结构吗？似乎无法复制添加为文件的目录有什么特殊之处吗？是否仅在压缩网络共享上的文件时使用？是否只有名称中包含特定字符的文件？是否仅当您从特定服务器运行脚本时？您是否尝试过指定程序集的全名（例如，
