How do I send an invitation request using the Facebook API?

Question

I would like to send an invitation request from my Facebook application written in C #.

Here is what I tried:

_fbService.API.notifications.sendEmail(DataList1.DataKeys[e.Item.ItemIndex].ToString(),"Invitation to play a game", "You are invited to play the game","");

This does not work; it sends a notification, not a request.
What am I doing wrong?

If you ask how you can send invitations to users who have not allowed your application (i.e. do not invite application users to use a new feature or participate in an event), you cannot use the API.

From the API documentation - Notifications.sendEmail :

API, , Notifications.sendRequest, , , - . . .
