Powershell是一种用于自动化任务和配置管理的脚本语言和命令行工具。它是Windows操作系统的一部分,可以通过命令行或脚本文件执行各种操作。 哈希表(Hash Table)是一种数据结构,也被称为关联数组或字典。它使用键值对的方式存储数据,通过计算键的哈希值来快速定位对应的值。哈希表具有快速的查找和插入操作,适用于需要频繁访问和
$hash.GetEnumerator().ForEach({"The value of '$($_.Key)' is: $($_.Value)"}) Adding and Removing Keys and Values Typically, when you create a hashtable you include the key-value pairs in the definition. However, you can add and remove key-value pairs from a hashtable at any time...
$content=Get-Content-Path$Path-Raw-ErrorActionStop$scriptBlock= [scriptblock]::Create($content)$scriptBlock.CheckRestrictedLanguage($allowedCommands,$allowedVariables,$true)$hashtable= ( &$scriptBlock) 它会将文件的内容导入scriptblock,然后在执行之前进行检查以确保它没有任何其他 PowerShell 命令。
In Powershell,you use hash literals to create a hashtable inline a script.Here it is a simple example: This example created a hashtable that contained three key-value pairs. The hashtable starts with the token “@{” and ends with “}”. Inside the delimiters, you define a set of key...
$hash= @{ Name ="Server30"System ="Server Core"PSVersion ="4.0"}$Asset= [pscustomobject]$hash$Asset 输出 System Name PSVersion --- --- --- Server Core Server30 4.0 从哈希表中Create非自定义对象 还可以使用哈希表为非自定义类创建对象。 为非自定义类创建对象时,需要命名空间限定的类型名称...
{ write-verbose "Beginning process loop" foreach ($computer in $computername) { Write-Verbose "Processing $computer" # use $computer to target a single computer # create a hashtable with your output info $info = @{ 'info1'=$value1; 'info2'=$value2; 'info3'=$value3; 'info4'=$...
To specify a calculated property we need to create a hash table; that’s what the @{} syntax does for us. Inside the curly braces we specify the two elements of our hash table: the property Name (in this case, Kybtes) and the property Expression (that is, the script block we’re ...

Next I noticed that it was using a foreach loop to create a hashtable. I’ve seen lots of code like this and in talking to a lot of new users, I’ve come the the conclusion that there are a set of beginner users that have a difficult time getting their heads around control structu...
