LINQ Distinct Query

Question

I have a C# application that loads a List of CLR objects called \"Tasks\". Each Task has the following properties:

public int ID { get; set; }
public int Typ         


        

Answer 1

Let me make sure I understand the problem: you have a sequence of tasks called allTasks, and you would like a sequence without duplicates of all the ids, yes?

Transform the sequence of tasks into a sequence of ids:

var ids = allTasks.Select(p=>p.TypeId);

Now you have a sequence of ids. You wish to filter out the duplicates from that sequence:

var distinctIds = ids.Distinct();

And you're done. Is that what you were after?
