c# - Comparison and re-structuring of 3 lists into a single list? -

so have following:

class item {     string name;     bool isselected; }

and have 3 lists:

list<item> list1; list<item> list2; list<item> list3;

my objective translate above single collection similar 'item' objects grouped (similar = objects have same 'name').

so want:

list<itemcontainer> resultantlist;

where:

class itemcontainer {     string name;     ilist<item> items;  //items same 'name' (potentially) }

notes:

the lists can have different number of items.
an 'item' object can belong 1 list. it's can have different objects same 'name' in different lists.
if no other object same 'name' found, still need included in resulting list.

what concise , clearest way of implementing this?

note: performance not concern.

thanks help.

you can try groupby,

var groupyname = list1.concat(list2).concat(list3).groupby(i => i.name);
