Question

I have got two lists of two different type which has the following common properties.

Id –>used to identify corresponding objects

Bunch of other Properties

ModificationDate

Need to compare these two lists based on Modification date.If the modified date is different (first list ModificationDate greater than second list’s ModificationDate then, copy all the properties if that item from first list to second.

Please let me know the best way to do this.

EDITED:Second list may or maynot contain all elements of the first and vice versa.My first list is always the source list. so if an item is present in list 1 and not present in list 2 we need to add it in list 2. also if an item present in list 2 but in not in list 1 then remove it from list2.
