In this program, we add a new elementCityto the hashtable. $person = @{ Name = "John Doe" Age = 35 } $person.City = "New York" We create a hashtable$personcontaining two key-value pairs. We add a new key-value pairCityto the hashtable. Write-Output "Name: $($person.Name)"...
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...
$table.Add(key, value)# 示例 :$table.Add("KunLong",76) 删除表中的某个键值对, 使用 Remove 方法: $table.Remove(key)# 示例 :$table.Remove("KingHans") 哈希表和数组一样支持选择多个值, 只需要在索引运算符中指定多个键: $table[key1,key2,...,keyn]$table[(key1,key2,...,keyn)]$tab...
哈希表, 即 HashTable. 在 PowerShell 中这样创建 HashTable: AI检测代码解析 $table = @{ key = value key = value } # 示例 : $table = @{} # 创建空表 $table = @{ # 创建有初始值的表, 下面的示例将使用这个表 "NullSlime" = 100 "MoYuro" = 96 "Muchen" = 94 "KingHans" = 88 }...
If you're ever in a situation where performance matters, this approach needs to be considered. I won't say that it's faster, but it does fit into the rule of If performance matters, test it. Multiselection Generally, you think of a hashtable as a key/value pair, where you provide...

This tells me that the add method takes two values. The first value is a key, and the second one is a value. Both of these input values are objects. The following code illustrates adding an additional key/value pair to the hash table stored in the $hash variable. The first line of ...
