convert values of List objects to string

Question

I have a list of objects, Model is:

public class Rule
{
    public bool IsValid { get; set; }
    public string RuleName { get; set; }
    public string Description { get; set; }
}

To get values of RuleName and IsValid from a list of Rules I did the following:

string.Join(", ", list.Select(rule=> new { rule.RuleName, rule.IsValid }))

Current output is in the following format:

{ RuleName = name1, IsValid = True}, { RuleName = name2, IsValid = False }

How to convert it to a format similar to the following without using loops?

name1 is True, name2 is False

whats so bad about loops? you could do it with linq but its still internally using loops — BugFinder

You can use string.format inside the select as string.Join(", ", list.Select(rule => string.Format("{0} is {1}", rule.RuleName, rule.IsValid.ToString()))); — Sivaprasath

It's simple with String.Join, Enumerable.Select and string interpolation(C#6):

string.Join(", ", list.Select(r=> $"{r.RuleName} is {r.IsValid}"));
