PowerTip: Creating an Empty Hash Table

hi ed,

here another variant:

PS II> $ht=New-Object Hashtable

PS II> $ht.GetType()

To create more than one:

@{} | sv hash1,hash2,hash3,hash4

Now you have 4 of them: $hash1, $hash2, $hash3, and $hash4.

Create and empty ordered hash table

#requires -version 3

$h=[ordered]@{}

@mjolinor & @Doug Finke

---> this is a great suggestion, thanks for sharing.

I can not test with ps3, are that this works ?

PS III> [ordered]@{} | sv hash1,hash2,hash3,hash

sorry for my english

@Walid It does indeed.

PS C:\> [ordered]@{}|sv hash1,hash2,has3,hash4

PS C:\>

PS C:\> $hash2.gettype()

IsPublic IsSerial Name                                     BaseType

-------- -------- ----                                     --------

True     True     OrderedDictionary                        System.Object

PS C:\>

Always, helpful.

Also folks, depending on your font, be careful about these 2 declarations:

@()

@{}

I've just about torn my hair out on a script when I accidentally declared an array instead of a hashtable...
