$hashtable.<key> <value> 例如: PowerShell 复制 $hash.Number 1 $hash.Color Blue 哈希表具有 Count 属性,指示 hashtable中的键值对数。 PowerShell 复制 $hash.count 3 hashtable 表不是数组,因此不能将整数用作 hashtable中的索引,但可以使用键名称为 hashtable编制索引。如果键是字符串值,请将...
hashtable是一个类似于数组的数据结构,除了你使用键来存储一个值(或者对象),它是一个基本的键/值对存储.首先,我们来创建一个空的hashtable $ageList= @{} 注意这里用的是花括号,而上面定义数组用的是小括号. 然后我们使得键来添加一些值: $key='Kevin'$value= 36$ageList.add($key,$value)$ageList.add...
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-value pairs where the key and value are separated by an equals sign “=”. Formally,the syntax for a ...
Example 11: Sort hashtables by key value Beginning in PowerShell 6,Sort-Objectsupports sorting ofhashtableinput by key values. The following example sorts an array of hashtables by the value of each hashtable'sweightkey. PowerShell
functionGet-DeepClone{ [CmdletBinding()]param($InputObject)process{if($InputObject-is[hashtable]) {$clone= @{}foreach($keyin$InputObject.Keys) {$clone[$key] =Get-DeepClone$InputObject[$key] }return$clone}else{return$InputObject} } } ...
虽然无法对哈希表进行排序,但可以使用哈希表的GetEnumerator()方法来枚举键和值,然后使用Sort-Objectcmdlet 对枚举值进行排序以显示。 例如,以下命令枚举$p变量中哈希表中的键和值,然后按字母顺序对键进行排序。 PowerShell PS>$p.GetEnumerator() |Sort-Object-PropertyKey Name Value --- --- Hash2 {[a,1]...
Hashtables are inherently unsorted, but when you’re printing a hashtable’s contents to the console, it can certainly be helpful to sort its contents by key. Although it’s not obvious, the way to do it is pretty easy. Let’s start with defining a hashtable and play with it ...
还可以让返回的对象是个HashTable——key-value的键值对数组,指定-AsHashTable参数: 8. Measure-Object:对列表项或输出结果进行计算 使用Measure-Object(measure)计算对象的数字属性以及字符串对象(如文本文件)中的字符数、单词数和行数。它计算某些类型对象的属性值。Measure-Object 执行三种类型测量,具体取决于命令中...
