LINQ: How do I concatenate a list of integers into comma delimited string?

Question

It\'s probably something silly I missed, but I try to concatenate a list of integers instead of summing them with:

integerArray.Aggregate((accumulator, piece) =&         


        

Answer 1

Just to add another alternative to @Marc's

var list = string.Join( ",", integerArray.Select( i => i.ToString() ).ToArray() );
