How to get a TreeView of a specific network directory

Question

Hi, (beginner in programming c#)

How can I get a TreeView of a specific Network directory and its subdirectories?

For my "Solution" in Visual Studio I also have created a settings form to select a "Projects" directory: e.g. "P:\Project".
This "Projects" directory I want to show in another form with TreeView/ListView.
The textbox where this directory is set is also a application setting (text) called Project_Dir.
