I am using hashtables (or dictionaries) more and more in Powershell – once I figured out that syntax $Hashtable.Key works, it turned out to be extremely useful as something similar to custom class.
However I run into an issue (maybe bug?) with sorting hashtables:
PS C:\> $X.Martin = "Zugec"
PS C:\> $X.Kamila = "Vlasakova"
PS C:\> $X.Filip = "Puntik"
PS C:\> $X.Tereza = "Liska"
PS C:\> $X | Sort Name
Name Value
---- -----
Filip Puntik
Kamila Vlasakova
Tereza Liska
Martin Zugec
As you can see, output is not sorted. After a while I tried to use raw method that is used in .NET:
PS C:\> $X.psbase.GetEnumerator() | Sort Name
Name Value
---- -----
Filip Puntik
Kamila Vlasakova
Martin Zugec
Tereza Liska
As you can see, everything is sorted out correctly in this case. Another scenario where you could use GetEnumerator is if you want to handle name (key) and value:
PS C:\> $X.psbase.GetEnumerator() | Where {$_.Name -eq "Martin"}
Name Value
---- -----
Martin Zugec
Without using enumerator, you got access only to values.
