$array = 1..5 | ForEach-Object { "ATX-SQL-$PSItem" } 通常,当我们考虑使用管道时,我们会想到典型的 PowerShell 单行命令。 可以通过 foreach() 语句和其他循环来利用管道。 因此,我们可以将项放到管道中,而不是在循环中向数组添加项。PowerShell 复制 ...
foreach($itemin$array) {Write-Output$item}Write-Output$array[3] 您也可以以相同方式使用索引來更新值。 PowerShell $array[2] =13 我只是初步了解了陣列,不過這應該能幫助我在進一步學習哈希表時更好地理解它們。 什麼是哈希表? 從一般意義上說,我會先從基本技術描述哈希表開始,再轉換到 PowerShell 使用...

$a = New-Object System.Collections.ArrayList That command gives us an empty array named $a. If we then want to populate that array with some information (which we probably do), all we have to do is call theAddmethod followed by the item we want to add to the array. For example, her...
Therefore we need to set $objAverage aside until later; one easy way to do that is to add the object to an array: Copy $colAverages += $objAverage And then it’s back to the top of the loop, where we repeat this process with the next player in the text file. OK, so then...
the actual values in the message text, a more robust way to access them is to retrieve the message with theGet-WinEventcmdlet, and then use thePropertiesarray of the message. Here’s an example of how this functionality can help unwrap a malicious attempt to encrypt and obfuscate a script...
