Looping through a hash, or using an array in PowerShell

Question

I\'m using this (simplified) chunk of code to extract a set of tables from SQL Server with BCP.

$OutputDirectory = \"c:\\junk\\\"
$ServerOption =   \"-SServe         


        

Answer 1

Here is another quick way, just using the key as an index into the hash table to get the value:

$hash = @{
    'a' = 1;
    'b' = 2;
    'c' = 3
};

foreach($key in $hash.keys) {
    Write-Host ("Key = " + $key + " and Value = " + $hash[$key]);
}
