How to do lists comprehension (compact way to transform a list into another list) in c#?

Question

In my code I frequently have the sequences like:

List<type1> list1 = ...;
List<type2> list2 = new List<type2>();
foreach(type1 l1 in list1)
{
    list2.Add(myTransformFunc(l1));
}

In Python, I can write it as

list2 = [myTransformFunc(l1) for l1 in list1]

Is there a compact way to write it in C#?

Answer 1

var newList = list.Select(x => YourTransformFunc(x)).ToList();

Or:

var newList = list.Select(YourTransformFunc).ToList();

Func signature should be:

type2 YourTransformFunc(type1 value)
{
}

Edit:

Extension methods Select and ToList are in System.Linq namespace.

Answer 2

You are thinking about this:

list1.ForEach(x=> list2.Add(myTransformFunc(x)));
