Using .Databases with a misspelled database name changes database name in SMO

This bug was found using dbatools: https://github.com/dataplat/dbatools/issues/8598

There are two ways to select a single database from the list of databases from a Microsoft.SqlServer.Management.Smo.Server object: $server.Databases | Where-Object Name -EQ <dbname> and $server['<dbname>'].

The first one works without problems. But the second one changes the casing of the name from the original one to the one used to query the database.

Here is the code to show that:

Import-Module -Name dbatools

# correct:
$server = [Microsoft.SqlServer.Management.Smo.Server]::new('sql01')
$server.Databases | Where-Object Name -EQ Master | Select-Object -ExpandProperty Name
$server.Databases['Master'] | Select-Object -ExpandProperty Name

# wrong:
$server = [Microsoft.SqlServer.Management.Smo.Server]::new('sql01')
$server.Databases['Master'] | Select-Object -ExpandProperty Name
$server.Databases | Where-Object Name -EQ Master | Select-Object -ExpandProperty Name

And here is a screenshot:

Yes, I'm using not the current version - but I don't have the current version at hand. But I think it will take you only minutes to test this in your test environment. If it is fixed with the current version: Sorry to bother you.

Inizia riproducendo il comportamento con gli esempi PowerShell usando Server.Databases e il relativo indicizzatore di stringhe. Poi segui l’implementazione alla base della ricerca nella raccolta Databases e aggiungi una copertura di regressione per una query con maiuscole e minuscole diverse o con un errore di ortografia. Il lavoro è completato quando interrogare un database non modifica più il nome originale del database né la relativa combinazione di maiuscole e minuscole.
