為了將一個元素加入至Hashtable,可以藉由將值指派給不存在的索引鍵名稱(§7.11.1),或者使用不存在索引鍵名稱的下標(§7.1.4.3)。 移除元素需要使用「Remove」方法。 例如 PowerShell $h1= @{ FirstName ="James"; LastName ="Anderson"; IDNum =123}$h1.Dept ="Finance"# adds element Finance$h1["Salar...
可以使用.Remove()函数删除键。 PowerShell $person.remove('age') 向它们赋值$null后只会留下一个具有$null值的键。 清除哈希表的常用方法是将其初始化为空哈希表。 PowerShell $person= @{} 虽然这样做确实有用,但请尝试改用clear()函数。 PowerShell ...
In Powershell,you use hash literals to create a hashtable inline a script.Here it is a simple example: 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...
The Remove-Module cmdlet removes the members of a module, such as cmdlets and functions, from the current session. If the module includes an assembly (.dll), all members that are implemented by the assembly are removed, but the assembly isn't unloaded. T

The real power of hash tables comes by adding key value pairs automatically from within the script. When used in this way, hash tables are essentially temporary data storage. The advantage a hash table has over an array is the key value pairs. The keys provide a way to retrieve the associ...
Here is sample code to recombine a script from its log messages:$created = Get-WinEvent -FilterHashtable @{ ProviderName=“Microsoft-Windows-PowerShell”; Id = 4104 } | Where-Object { <Criteria> }$sortedScripts = $created | sort { $_.Properties[0].Value } $mergedScript = -join ($...
