Passing SharePoint List values to DataSet to build email in Powershell

Hi,

I'm new to powershell and SharePoint... I'm creating script to generate an email body and send it to the assignee.  Currently we don't have VS2010 so the only way i can do this that i know is using powershell.

No| Status | assignee
1| Open | Dona
2| Open | Dona
3  | Open  | Rey
4  | Open  | Charice

Can you please tell me how to pass the sharePoint list items in a dataset so i can generate this kind of email below. For example ill be sending the email to Dona.

Sample Email to Dona.

Item No: 1  / Status: Open /Assignee: Dona

Item No:2 /Status: Open / Assignee: Dona

Thanks in Advance.
