function ArrayToHash
{
Param($array, $indexproperty)
$hash = @{}
$array | %{$hash[$_.$indexproperty] = $_}
$hash
}
This should turn any enumerable collection into a hash using the named
property as an index. For example, you can collect filesystem objects from
the current location and use their FullName property as the index like this:
ArrayToHash (gci) FullName
or, to collect them into a variable:
$h = ArrayToHash (gci) FullName
