Visual Studio 2008 - form tool that allows you to locate a file on your drive

What is the name of the tool that you can load on a开发者_运维技巧 form, that when a user clicks it it allows them to find a find by navigatin the drive? And if I remember rightly don't I have to add a reference to the project to find it?? Just can't remember the name...

I am using visual studio 2008, c# project.

Thanks, R

OpenFileDialog is the name, there is also FolderBrowserDialog
