数组(Array) 数组是一种有序的数据结构,可以存储多个相同类型的元素。在 PowerShell 中,可以使用@()符号创建数组,例如: 代码语言:txt 复制 $array = @(1, 2, 3, 4, 5) 哈希表(Hashtable) 哈希表是一种键值对(Key-Value Pair)的数据结构,可以通过键来访问对应的值。在 PowerShell 中,可以
$newKeyValuePair = @{ "key" = "value" } $jsonContent.array += $newKeyValuePair 最后,将更新后的JSON内容转换回字符串,并使用Set-Content命令将其写入到原始JSON文件中,例如: 代码语言:txt 复制 $jsonString = $jsonContent | ConvertTo-Json -Depth 100 $jsonString | Set-Content -Path "...
$array = @(1..4) $array[2] = 114514 echo $array[2] # 输出 114514 1. 2. 3. PowerShell 的数组还支持获取多个值, 它返回一个新的数组: $array = @(1..4) $array2 = $array[0, 2] echo $array2[0] # 输出 1 echo $array2[1] # 输出 3 1. 2. 3. 4. 添加元素, 可以用 ‘...
$myArray = 1,2,3,4,5,6,7,8,9,10; [int] $sum = 0; foreach ($val in $myArray) { write-host ("Index with value:$val"); $sum = $sum + $val; } Write-host(“The sum is: $sum”); 3.Associative Arrays 类似于C++ map, key,value pair. ## Declaration syntax: # $<ar...
Remove(Key) For example, to remove theTime=Nowkey-value pair from the hashtable in the value of the$hashvariable, type: PowerShell $hash.Remove("Time") You can use all of the properties and methods of Hashtable objects in PowerShell, includingContains,Clear,Clone, andCopyTo. For more...
foreach($pairin$table.GetEnumerator()) {echo("{0}: {1}"-f($pair.Key,$pair.Value)) } 当通过foreach对哈希表进行迭代时, 不可以对哈希表进行删减: 4. 脚本函数 - 关于函数 PowerShell 官方文档 : 关于函数 PowerShell 中定义函数很简单, 它的本质是脚本块(ScriptBlock): ...
Arrays and array elements are discussed in §9.5.2.4 Hashtable key/value pairsA Hashtable is created via a hash literal (§2.3.5.6) or the New-Object cmdlet. A new key/value pair can be added via the [] operator (§7.1.4.3).Memory for creating and deleting Hashtables is managed ...

Array indexes are zero-based, so the first object is indexed as [0]. You can also use negative indexes to get the last values. Hash tables are indexed by key value. Given a list of indices, the index operator returns a list of members corresponding to those indices. PowerShell Copy ...
APSObjectis very much like a hashtable where data is stored in key-value pairs. You can create as many key-value pairs as you like for eachPSObject. Creating a PSObject As mentioned, the PowerShellPSObjectuses a key & value pair type structure. To store data in thePSObjectall you need...
