Question

I need to convert LinkedList<String> to LinkedList<int> using Linq ?
What is the best way to achieve this functionality ?

Answer 1

LinkedList<T> contains a constructor that receives an IEnumerable<T> and initializes based on it. So all you have to do is use LINQ’s Select operator to convert all strings to int:

LinkedList<string> stringList = ...;
IEnumerable<int> ints = stringList.Select(str => int.Parse(str));
LinkedList<int> intList = new LinkedList<int>(ints);
