Concatenating list item properties

Question

I'm looking for an elegant way of creating a readable form some property of all items living in a Generic.List.

Let me illustrate it by an example. I have a data structure like this:

public class InfoItem {
    public string Name { get; set; }
    public string Description { get; set; }
}

Here is how I would use it in my code:

List<InfoItem> data = new List<InfoItem>();
data.Add(new InfoItem() { Name = "Germany", Description = "Describes something" });
data.Add(new InfoItem() { Name = "Japan", Description = "Describes something else" });
data.Add(new InfoItem() { Name = "Austria", Description = "And yet something else" });

Now, what I want to get, is a string like "Germany, Japan, Austria". Is there some LINQ or generics magic that would do it better than this primitive loop?

string readableNames = "";
foreach (var item in data) {
    readableNames += item.Name + ", ";
}
readableNames = readableNames.TrimEnd(new char[] { ',', ' ' });

Answer 1

Just use string.Join and Enumerable.Select:

string readableNames = string.Join(", ", data.Select(i => i.Name));

Answer 2

Easy

var str = String.Join(", ", data.Select(x => x.Name));
