问题解决 $FinalCityList = @($CityList | Where-object -filterScript {$_[2] -like "Chong*"}) 把Where-Object 方法用 @() 进行对象转换即可。 完整的PowerShell脚本为: $CityList = [System.Collections.ArrayList]::new() $CityList.Add(@(“A”,“11”,“Cheng Du”)) | Out-Null $CityList...
Where-Object 参考 反馈 模块: Microsoft.PowerShell.Core 根据集合的属性值从集合中选择对象。 语法 PowerShell Where-Object[-InputObject <PSObject>] [-Property] <String> [[-Value] <Object>] [-EQ] [<CommonParameters>] PowerShell Where-Object[-InputObject <PSObject>] [-FilterScript] <ScriptBlock...
Script blocks can be used in conjunction with theWhere-Objectcmdlet. They are especially useful when you need more advanced filtering options. Script blocks allow users to add multiple filters to the sameWhere-Objectstatement. Here is a basic example of aWhere-Objectstatement using a script block...
从$FinalCityList 的打印结果分析,当 Where-Object 查看到结果只有一个的时候,就把结果对象进行了多维到一维的转换。所以结果变为了一个包含三行内容的一位数组。 问题解决 $FinalCityList = @($CityList | Where-object -filterScript {$_[2] -like "Chong*"}) 1. 把Where-Object 方法用 @() 进行对象转...

首先看看where-object筛选: Get-WmiObject -Class Win32_Product -ComputerName . | Where-Object -FilterScript {$_.Name -eq "Microsoft .NET Framework 2.0"} | Format-List -Property * 1. 下面是WQL语法筛选的两种格式(一个是常规方式,另外一个是转义符方式) ...
PowerShell是一种任务自动化和配置管理框架，由Microsoft为Windows操作系统提供。它包含了一个命令行shell和一个脚本语言环境。对于系统管理员和开发者来说，PowerShell是一种强大的工具，可以用于管理和自动化任务。在本篇文章中，我们将专注于其中一个特定的命令：Get-WinEvent。
-contains運算子會檢查集合中是否包含您的值。 一旦找到匹配項目,就會傳回$true。 PowerShell $array=1..6if($array-contains3) {# do something} 這是查看集合是否包含您值的慣用方式。 每次使用Where-Object(或-eq)遍歷整個清單,速度會明顯變慢。

All the functions and filters in PowerShell are automatically stored in theFunction:drive. This drive is exposed by the PowerShellFunctionprovider. When referring to theFunction:drive, type a colon afterFunction, just as you would do when referencing theCorDdrive of a computer. ...
