Thanks

Answer 1

Read the Manual:

http://msdn.microsoft.com/en-us/library/fxeahc5f.aspx

Directory.Delete(folderPath, true);

Answer 2

dir.Delete(true); // true => recursive delete

Answer 3

The Directory.Delete method has a recursive boolean parameter, it should do what you need

Answer 4

Err, what about just calling Directory.Delete(path, true); ?

Answer 5

Try:

System.IO.Directory.Delete(path,true)

This will recursively delete all files and folders underneath "path" assuming you have the permissions to do so.

Answer 6

You should use:

dir.Delete(true);

for recursively deleting the contents of that folder too. See MSDN DirectoryInfo.Delete() overloads.
