C # the realization of the function of the List-CodePudding

List A is A, b, d, e,
List B is a, B, c, d, f

To achieve a C, a, b, C, d, e, f

How to implement?

Linq and difference and complement
Do it again, all the 4 90% of the things you can do

The remaining 10% is left connection, connection (cartesian), selectmany this

C # Linq intersection and set, difference set to heavy

List ListA=new List (a);
List By=new List (a);
List ListResult=new List (a);

ListResult=ListA. Distinct (.) ToList ();//to heavy
ListResult=ListA. Except (by). ToList ();//difference set
ListResult=ListA. Union (by). ToList ();//and set
ListResult=ListA. Intersects (by). ToList ();//intersection
