你没有说你有什么问题。您没有显示错误并解释您的代码问题。
如果您尝试对纯文本文件以外的任何内容执行此操作，这将永远不会起作用。
当你在这两种情况下都可以使用 Select-String 时，你为什么还要调用一个 exe？
为什么要混合别名？
这有什么期待……
Matched regex $pattern*
... Select-Object 永远不会知道这是什么，因此会失败。您必须在 Select 中使用合法属性（或计算属性）。
运行您的代码，稍作修改，返回指定的正则表达式模式的结果。
Findstr details
# /m Prints only the file name if a file contains a match.
# /p Skips files with non-printable characters.
# /r Processes search strings as regular expressions. This is the default setting.
# /c:<String> Uses the specified text as a literal search string.
$pattern1 = 'localhost'
$pattern2 = 'COMPUTERNAME'

where-Object { $PSItem | Select-String -pattern $pattern1, $pattern2 } |
Select-Object -Property FullName, CreationTime, LastWriteTime

会给你这个...

...您将看到它永远不会返回，因此您无法检索它，因为它永远不会在您的代码中传递，并且无法通过您编码的方式返回。
您还必须考虑到该模式匹配可以是您传入的一个或多个模式，因此，它不是每行单个条目，而是一个数组。因此，现在您需要决定当所有模式都匹配时，您希望该输出的外观。
例如，修改代码以处理捕获该模式，确实会给出输出...
（现在，这只是一个快速的组合，并不优雅。）
$pattern1 = 'localhost'
$pattern2 = 'COMPUTERNAME'
Get-ChildItem -Recurse -file -force -path "E:\Temp" |
Where-Object { findstr.exe /mprc:. $PSItem.FullName } |
where-Object { $PatternMatch = (Select-String -pattern $pattern1, $pattern2 -Path $PSItem.FullName )
Select-String -pattern $pattern1, $pattern2 -Path $PSItem.FullName
} |
Select-Object -Property FullName, CreationTime, LastWriteTime,
@{Name = 'PatternMatch';Expression = {$PatternMatch.Pattern}}
# Results

...现在，这是您想要的最后一列的外观还是您想要每个模式匹配一行，所以，所有的东西都将是每列一个条目？
如果您正在查看 1:1 比赛，即每次比赛多次显示文件，那么您最终需要明确的循环工作。
例如：
$pattern1 = 'localhost'
$pattern2 = 'COMPUTERNAME'
Get-ChildItem -Recurse -file -force -path "E:\Temp" |
Where-Object { findstr.exe /mprc:. $PSItem.FullName } |
ForEach {
Select-String -pattern $pattern1, $pattern2 -Path $PSItem.FullName |
Select-Object -Property Path, Pattern,
@{Name = 'CreationDate';Expression = {(Get-ChildItem -Path $PSItem.Path).CreationTime}},
@{Name = 'LastWriteTime';Expression = {(Get-ChildItem -Path $PSItem.Path).LastWriteTime}}
}
# Results
Path Pattern CreationDate LastWriteTime
