Question

Let’s say I have this object:

public class Role {
    public string Name { get; set; }
    public string Slug { get; set; }
    public DateTime DateAssigned { get; set; }
    ...
}

A member can have multiple roles: member.Roles = List<Role>();

If I wanted to join the member’s roles into a comma separated list of the role names, is there an easy way (similar to string.Join(",", member.Roles); – which doesn’t work because a role is a complex type)?

Answer 1

using System.Linq

string.Join(",", member.Roles.Select(r => r.Name))
