Get a list of distinct values in List
c#, distinct, linq, list
Solution
Notes.Select(x => x.Author).Distinct();
This will return a sequence (`IEnumerable<string>`) of `Author` values -- one per unique value.
Problem
In C#, say I have a class called `Note` with three string member variables. ``` public class Note { public string Title; public string Author; public string Text; } ``` And I have a list of type `Note`: ``` List<Note> Notes = new List<Note>(); ``` What would be the cleanest way to get a list of all distinct values in the Author column? I could iterate through the list and add all values that aren't duplicates to another list of strings, but this seems dirty and inefficient. I have a feeling there's some magical Linq construction that'll do this in one line, but I haven't been able to come up with anything.
