Is there an AddUnique method similar to Addrange() for alist in C#

Question

I have a list in C#:

       var list = new List();
       list.AddRange(GetGreenCars());
       list.AddRange(GetBigCars());
       list.AddRange(         


        

Answer 1

One choice is to add them and remove the repeated ones:

var list = new List();
list.AddRange(GetGreenCars());
list.AddRange(GetBigCars());
list.AddRange(GetSmallCars());
list = list.Distinct().ToList();
