ForEach-Object循環中字符串的破壞性處理？

Question

我是PowerShell的新手，瞭解cmdlet的工作原理。我有三條路徑，我想確保它們都有尾部斜線。下面的代碼應該檢查每一個並附加一個\如果不存在，但它不會最終改變它們本身。

# append trailing slash if not present 
$engineXCopyPath, $engineXBackupPath, $enlistmentBuildTargetPath | ForEach-Object { 
    if(!$_.EndsWith("\")) { 
     $_ += "\" 
    } 
} 

感謝您的幫助！

試試這樣說：

# append trailing slash if not present 
$engineXCopyPath, $engineXBackupPath, $enlistmentBuildTargetPath = 
$engineXCopyPath, $engineXBackupPath, $enlistmentBuildTargetPath | ForEach-Object { 
    if(!$_.EndsWith("\")) { 
     $_ + "\" 
    } 
    else { 
     $_ # keep the original value if appending isn't needed 
    }  
}
