Hi
Found solutions as below

            byte[] ticksAsBytes = BitConverter.GetBytes(DateTime.Now.Ticks);
            Array.Reverse(ticksAsBytes);
            int increment = Interlocked.Increment(ref guidCounter);
            byte[] currentAsBytes = BitConverter.GetBytes(increment);
            Array.Reverse(currentAsBytes);
            byte[] bytes = new byte[16];
            Array.Copy(ticksAsBytes, 0, bytes, 0, ticksAsBytes.Length);
            Array.Copy(currentAsBytes, 0, bytes, 12, currentAsBytes.Length);
            Array.Copy(GuidUtil.machineId, 0, bytes, 8, machineId.Length);

            //return bytes.TransfromToGuidWithProperSorting();

            return new Guid(bytes);

But I didn't transform it using TransfromToGuidWithProperSorting() because found that it doesn't sorted actually by dump the generated guid to SQL table and added clustered index to the field.
