powershell 的选择字符串没有返回结果

我尝试使用 powershell 的选择字符串在文档中查找特定的单词（Gate），但它没有返回任何结果。

Get-ChildItem -path '.\somedocument.docx' | Select-String -pattern 'Gate'

我做错了什么？我正处于学习 powershell 的初始阶段。

由于您是 PoSH 世界的新手。首先获得一些指导/培训非常重要，以防止您迷失/沮丧。请参阅此讨论。

CConard96 关于 Get-Children 的说法是正确的，您可以使用 Get-Content 或 .Net 文件库读取文件。

PowerShell 可以完全访问 Windows 提供的任何 .Net 库、COM 和 DOM 接口。

因此，您需要了解并使用正确的工具集。对于您所追求的目标，我不会将 Select-String 用于此用例。

您可以使用 PoSH 来执行此操作，但您还必须使用 Word DOM。例如：

# Instantiate Word object
$wd = New-Object -com word.application

# Oepn a Word doc
$doc = $wd.Documents.Open('D:\Documents\Microsoft Graph API.docx')

# Read all the doc contents
$doc.Range().text

您不需要上述所有方法，因为我已经为您解决了用例，因为它可以简化。然而，您看，这是可以做到的。

本论坛上还有其他示例。

从 Word 文档中获取特定数据 https://www.reddit.com/r/PowerShell/comments/38dcm7/getting_specific_data_out_of_a_word_document

您甚至可以将文档转换为其他文件类型，然后使用 cmdlet 读取它，但这只是额外的工作。如果没有必要，为什么要这么做呢？
