Linq query to get the distinct values in a list

Question

Suppose this is my member class

class Member 
{
    public string CategoryId { get; set; }
    public string MemberName { get; set; }
    public int Distance { g         


        

Answer 1

This also works, if you do not require items ordered by (little modified Kjartan's answer)

var grouped = list.GroupBy(item => item.CategoryId).ToList();
var shortest = grouped.Select(grp => grp.OrderBy(item => item.Distance).First());
