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....
$hash.values Output 复制 1 Square Blue 每个键名称也是 hashtable的属性,其值是键名称属性的值。 使用以下格式显示属性值。 Syntax 复制 $hashtable.<key> <value> 例如: PowerShell 复制 $hash.Number 1 $hash.Color Blue 哈希表具有 Count 属性,指示 hashtable中的键值对数。 PowerShell 复制 ...
You might have noticed that the keys property didn’t return the keys in alphabetical order. This is because of the way hashtables work; i.e., keys are randomly distributed in the table to speed up access. If you do need to get the values in alphabetical order,here’s how you can d...
如果您需要在匯入時是[hashtable],則必須使用Export-CliXml和Import-CliXml命令。 將JSON 轉換為哈希表 如果您需要將 JSON 轉換成[hashtable],我知道有一種方式可透過 .NET 中的JavaScriptSerializer來執行此動作。 PowerShell [Reflection.Assembly]::LoadWithPartialName("System.Web.Script.Serialization")$JSSeriali...
最常用的属性是Count、Keys、Values和Item。 指示对象中的键值对数的 Count属性。 Keys属性是哈希表或字典中的键名集合。 PowerShell PS>$hash.Keys three21PS>$dictionary.Keys12three Values属性是哈希表或字典中的值的集合。 PowerShell PS>$hash.Values3two one PS>$dictionary.Values one two3 ...
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. Status is an enumerated property. Stopped has a value of 1 and Running ...
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 ...
Selects objects from indexed collections, such as arrays and hash tables. 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. ...
