c# - Eliminate consecutive duplicates of list elements

Question

Is there a "nice" way to eliminate consecutive duplicates of list elements?

Example:

["red"; "red"; "blue"; "green"; "green"; "red"; "red"; "yellow"; "white"; "white"; "red"; "white"; "white"] 

should become

["red"; "blue"; "green"; "red"; "yellow"; "white"; "red"; "white"]

--By "nice" I mean most readable and understandable to a new user and fast execution :)

Answer 1

A simple and very readable solution:

List<string> results = new List<string>();
foreach (var element in array)
{
    if(results.Count == 0 || results.Last() != element)
        results.Add(element);
}
