LINQ list to sentence format (insert commas & “and”)

Question

I have a linq query that does something simple like:

var k = people.Select(x=>new{x.ID, x.Name});

I then want a function or linq lambda,

Answer 1

This can be the way you can achieve your goal

var list = new[] { new { ID = 1, Name = "John" }, 
                   new { ID = 2, Name = "Mark" }, 
                   new { ID = 3, Name = "George" }
                 }.ToList();

int i = 0;

string str = string.Empty;

var k = list.Select(x => x.ID.ToString() + ":" + x.Name + ", ").ToList();

k.ForEach(a => { if (i < k.Count() - 1) { str = str +  a; } else { str = str.Substring(0, str.Length -2) + " and " + a.Replace("," , ""); } i++; });
