Powershell 提取 Zip

当我在普通 PowerShell 窗口中运行此命令时，它运行正常：

Add-Type -AssemblyName System.IO.Compression.FileSystem; [System.IO.Compression.ZipFile]::ExtractToDirectory("c:/program/compressed.zip","c:/program")

但是当我按如下方式运行它时：

powershell Add-Type -AssemblyName System.IO.Compression.FileSystem; [System.IO.Compression.ZipFile]::ExtractToDirectory("c:/program/compressed.zip","c:/program")

或者

cmd /c powershell Add-Type -AssemblyName System.IO.Compression.FileSystem; [System.IO.Compression.ZipFile]::ExtractToDirectory("c:/program/compressed.zip","c:/program")

我收到此错误：

At line:1 char:119

                                                                  ~

Unexpected token 'compressed.zip' in expression or statement.

在前面添加 PowerShell 怎样才能使其工作？

感谢您的时间。

命令提示符（批处理）首先处理命令​​和参数，因此要小心任何可能被解释为 cmd 符号（在您的情况下为双引号）的内容，因为 cmd 会删除它们。

运行 powershell 命令时，我更喜欢引用实际的 powershell 部分：

powershell.exe -Command "Add-Type -AssemblyName System.IO.Compression.FileSystem; [System.IO.Compression.ZipFile]::ExtractToDirectory('c:/program/compressed.zip','c:/program')"
