I have 2 classes like below

class ParentAddress
CommonId
Id
Name
ChildAddress

class ChildAddress
CommonId
City
State

I got 2 lists from db with the above fields

I want to combind child list items to parent list items



like below which has list

ParentAddress
       CommonId
       Id
       Name
       ChildAddress
           CommonId
           City
           State


What I have tried:

tried to maintain 2 separate dictionaries and try to get by key and add object but not working.
Could you please suggest a better approach?

Just add the ChildAddress object to the ParentAddress object. As you would for any variable of the class.

For a "simple" list, you merge both sets and "indent" the children; by padding a string (name) on the left with spaces, for example. You can construct entire trees this way without actually building a tree. The "indent level" (size) is one way to know what level you're on.

There are 2 solutions: 1) as Richard pointed out, just add the children class (or a list of it) as property to your parent class and 2) add the parent class as property to your children class. Instead of adding the classes, you could also add the corresponding IDs and use class methods to GetParent() or GetChildren().
