C# .NET Web Service output

Question

Hi, Using the .NET Framework to build a Web Service that outputs a certain struct or object. The output should look like this (XML):

value value value value value value value value

*CLIST can contain 1 or more elements. **There can be several E but it should contain only one F-G pair. There is no problem to create a class or struct for one object but I run into trouble when it comes to arrays (CLIST and DLIST above). How can I structure a class or other with the output above in mind?
