This should hopefully get you started:

Call Directory.GetAccessControl on the directory which gives you a DirectorySecurity instance that has a GetAccessRules which will give you a list of AuthorizationRule and if you cast that to FileSystemAccessRule then you should be able to get out the FileSystemRights and IdentityReference to get out the information you want.
