copy structure of the sourcefolder to destinationfolder?

Question

I am working on C#.net console application in my app i have two folders 
1)D:\Working Projects\Alticore\AssetXML\LIS,  
2)D:\Working Projects\Alticore\AssetXMLProcessed. 

I want to copy only sub-folder(i.e LIS) from D:\Working Projects\Alticore\AssetXML\LIS to D:\Working Projects\Alticore\AssetXMLProcessed.

This should exactly like this `"D:\Working Projects\Alticore\AssetXMLProcessed/LIS" and Source folder should be remain same i.e don't want to move source folder to destination folder.

Any solution to this problem I'll be appreciate.
