Hash table in PowerShell

hashtable is easy to create, access and manipulate.

we simply use

1
$hashTable = @{}

to create an empty hash table.

and use

1
$hashTable.color = "Blue"

to set the key and value pair.

 

refer to http://ss64.com/ps/syntax-hash-tables.html, it is very flexible to use hash table.

one thing I want to point out is that whenver we want to traverse the hashtable, what can we do ?

just like an Array in PowerShell, using ForEach can do it.

 

For hashtable, we can use like:

1
2
3
4
foreach ($dog in $dogs.GetEnumerator())
{
       # do what you like
}

  or

1
$hashtable.GetEnumerator() | ForEach-Object { … }
