arrays - Quick File to Hashtable in PowerShell -

given array of key-value pairs (for example read in through convertfrom-stringdata), there streamlined way of turning hashtable or similar allow quick lookup? i.e. way not requiring me loop through array , manually build hashtable myself.

example data

10.0.0.1=alice.example.com 10.0.0.2=bob.example.com 

example usage

$names = gc .\data.txt | convertfrom-stringdata // $names object[] $map = ? // $map should hashtable or equivalent echo $map['10.0.0.2']  // output should bob.example.com 

basically i'm looking a, preferably, built-in file-to-hashtable function. or array-to-hashtable function.

note: @mjolnior explained, got hash tables, array of single value ones. fixed reading file -raw , hence didn't require array hashtable conversion. updated question title match that.

convertfrom-stringdata create hash table.

you need give key-value pairs single multi-line string (not string array)

$map = get-content -raw .\data.txt | convertfrom-stringdata  $map['10.0.0.2']  bob.example.com 

when use get-content without -raw switch, you're giving convertfrom-stringdata array of single-line strings, , it's giving array of single-element hash tables:

$map = get-content .\data.txt | convertfrom-stringdata  $map.gettype()  $map[0].gettype()  $map[0]    ispublic isserial name                                     basetype                                                                    -------- -------- ----                                     --------                                                                    true     true     object[]                                 system.array                                                                true     true     hashtable                                system.object                                                                key   : 10.0.0.1 value : alice.example.com name  : 10.0.0.1
