CSV string handling

Question

Typical way of creating a CSV string (pseudocode):

1. Create a CSV container object (like a StringBuilder in C#).
2. Loop through the strings you want to ad

Answer 1

You could use LINQ to Objects:

string [] strings = contactList.Select(c => c.Name).ToArray();
string csv = string.Join(",", strings);

Obviously that could all be done in one line, but it's a bit clearer on two.
