F# List.map equivalent in C#?

Question

Is there an equivalent to F#'s List.map function in C#? i.e. apply a function to each element in the list and return a new list containing the results.

Something like:

    public static IEnumerable<TResult> Map<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, TResult> funky)
 {
  foreach (TSource element in source)
   yield return funky.Invoke(element);
 }

Is there already a built in way or should I just write the custom extension?

Answer 1

That is LINQ's Select - i.e.

var newSequence = originalSequence.Select(x => {translation});

or

var newSequence = from x in originalSequence
                  select {translation};

Answer 2

ConvertAll is the built-in function:

public List<TOutput> ConvertAll<TOutput>(
    Converter<T, TOutput> converter
)
