在Powershell中,可以使用Hashtable类来创建哈希表。哈希表中的键和值可以是任意类型的数据。要排序包含数组的哈希表,可以使用Sort-Object cmdlet来对哈希表中的键进行排序。 下面是一个示例代码,演示如何创建一个包含数组的哈希表,并对其进行排序: 代码语言:txt 复制 # 创建包含数组的哈希表 $hash
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 hash table might contain a series of IP addresses and com...
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 ...
