You can also get the hashtable key value as a regular property of a PowerShell object: Note. By default, when you create a hashtable object using the @ {} syntax, its keys are not case-sensitive (where username and UserName are the same). To change the value of a key in a hashtable, use the assignment operator (=) or the Set_Item () method:

It provides a fast way to retrieve values based on their associated key. In PowerShell, a hash table is created using the “@ {}” symbol. The key is on the left side of the symbol, and the value is on the right side of the symbol. PowerShell hash tables are similar to dictionaries in other languages.

Below is the syntax for adding a key-value pair to a PowerShell hashtable, where: $hashtable – The name of the hashtable. $key – The name of the key, which are case-insensitive. For example, “FirstName” and “firstname” would be considered the same key in a hashtable $value – The value to associate with the key.

Or Use the Where-Object cmdlet to get all values without keys of a hash table in PowerShell. This approach is useful when we want to get all values in the form of an object. After creating a hash table with three key-value pairs, it accessed the PSObject property of the $hashTable object and its Properties collection.
