Question

I have a list called listitems which contains information on items.

I want to separate each list item by a comma and put it in a string called gh

But when I use the following I get the output as :

",a,b" which is incorrect

but I want the output as "a,b".

How can I modify the code ?

foreach(var a in listitems)
{
  gh = gh +"," + a;
}

Answer 1

string gh = String.Join(",", listitems); //
