selenium to select an option from drop down menu

Is it possible to make selenium select a 'title' among many in a drop down menu?

That is I have a windows app which gets a user input. I want selenium to select an option from a drop down menu based on what the user entered. It is not possible to select that based on CSS,Id or any other attribute since we can't predict what the user enters. So, I think the only possibility is that to search the exact string inside the drop down menu.

I could make selenium focus on that drop down and the menu is now viewable. I want the rest of the things done..Can this be implemented?If yes, Can anyone give me an idea on how to achieve that?

Would be nice if you can give me an idea based on c# since I am using it for the development.

Selenium can be used only for Web application not for Windows application.
