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);
            }
        }
    }
}
