Tips & Tricks:

Remember to free buffer, see NetApiBufferFree

Sample Code:

static void Main(string[] args)

        {
            IntPtr buf;
            if (args[0] != "")
            {
                int res=NetDfsGetInfo(args[0], null, null, 4, out buf);      
                if (res == 0)
                {
                    try
                    {
                        DFS_INFO_4 info = (DFS_INFO_4)Marshal.PtrToStructure(buf, typeof(DFS_INFO_4));
                        Console.WriteLine("{0}, {1}, {2} ", info.EntryPath, info.Comment, info.NumberOfStorages);

                        for (int i = 0; i < info.NumberOfStorages; i++)
                        {
                            IntPtr pStorage = new IntPtr(info.Storage.ToInt64() + i * Marshal.SizeOf(typeof(DFS_STORAGE_INFO)));
                            DFS_STORAGE_INFO storage = (DFS_STORAGE_INFO)Marshal.PtrToStructure(pStorage, typeof(DFS_STORAGE_INFO));
                            Console.WriteLine("  {0}, {1}, {2} ", storage.ServerName, storage.ShareName, storage.State);
                        }
                    }
                    finally
                    {
                        NetApiBufferFree(buf);
                    }
                }
            }
        }
