Describes how to create, use, and sort hashtables in PowerShell. Long description A hashtable, also known as a dictionary or associative array, is a compact data structure that stores one or more key-value pairs. For example, a hashtable might contain a series of IP addresses and computer...
我在工作中经常用到它,现在想停下来讨论一下它(hashtable).昨天夜里小组会议后我教了一些同事如何使用hashtable,我很快意识到初识hashtable时我也曾经有与他们相同的困惑.Hashtable在powershell里着实非常重要因此我们需要对它有充会的理解. hashtable是元素的集合 首先,我想让你们把hastable看作传统意义上定义的集合....
PS (11) > $user[[string[]] ($user.keys | sort)] John Smith 555-1212 You’ll notice something funny about the last example: we had to cast or convert the sorted list into an array of strings. This is because the hashtable keys mechanism expects strings, not objects, as keys. There...

字典排序: 字典(也称为哈希表或关联数组)是一种存储键值对的数据结构。在Powershell中,可以使用Hashtable类型来表示字典。要对字典进行排序,可以使用Sort-Object命令,结合Get-Enumerator命令来获取字典的键值对并进行排序。下面是一个示例: 该示例中,我们创建了一个字典$dict,其中包含三个键值对。通过$dict.Keys获取...
Hashtable/Dictionary类型 哈希表就是一个Key-Value对的集合。哈希表的创建格式如下: @{Key1=Value1;Key2=Value2;…} 这里Key一般是字符串,但是并不需要用引号引起来(当然,使用了引号更好),Value可以是任意类型。比如我们创建一个员工和部门的Hashtable,命令如下: ...
Ergh! What happened? Well, without going into tons of detail, it has to do with the type that backs HashTable and how you can’t sort the object itself. You’ve got to generate a list of key-value pairs and sort that. Here’s the correct way to do it: ...
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} } } ...
The service objects are sent down the pipeline to the Sort-Object cmdlet. Sort-Object uses the Property parameter with a hash table to specify the property names and sort orders. The Property parameter is sorted by two properties, Status in descending order and DisplayName in ascending order. ...
