Question about comparing an array of names to a hash table

Question

I'm still learning Powershell but feel like I have the basics now. I have a new project I'm working on and want some input as the best way to do this:
The Problem:
Let's say you have a list of several hundred video game titles and the dollar value of each in a text or two column CSV file.
The example CSV file looks likes this:
Game, Price
Metroid, $15.00
The Legend of Zelda!, $12.00
Mike Tyson's Punch-Out!, $18.00
Super Mario Bros., $16.00
Kung Fu, $7.00
You have another list of just the video game titles, this most likely is just a text file with each title listed on its own line.
The example text file looks like this:
Kung Fu
Metroid
Mike Tysons Punch-Out
Legend of Zelda
What I think would happen in the Script:
Use import-csv and create a hash table that will contain a key = Title and the value = the price.
Use import-csv and create an array for the title names.
Foreach loop through each Game Title and match the value against the Hash Table, if there's a match found, put that into another array that will later add all prices of each item and give you a total sum.
The challenge:
So far when I try and do one line examples of comparing names against the hash table it seems to only work with exact name matches. In the above example I've purposely made the game titles slightly different because in the real world people just write things
differently.
With that said, I've tried using the following single line to match things up and it only seems to work if the values match exactly.
$hash_table.ContainsKey("Game Title")
Is there a regex I should use to change the input of the game titles before creating the hash table or doing the compare? Is there another matching operator that is better and matching with String values that have slightly different grammar. An example would
be the game "The Legend of Zelda". Sometimes people just put "Legend of Zelda", that's close but not exact. I think using a regex to remove extra spaces and symbols would work, but what about for matching of words or letters??
Any ideas would be very helpful and thanks!

Answer 1

There's no pat answer for this.
You can create an array from the hash table keys:
$hashtable = @{"The Legend of Zelda" = 15.00}
$titles = $hashtable.getenumerator() | select -ExpandProperty Name
And then test that using a wildcard match:
$titles -like "*Game Title*"
and see if it returns just one match.  If it does then use that match to do your lookup in the hash table.  If it returns 0, or more than one match then you need to check the spelling or qualify the title search some more.
