Concatenating objects with linq

Question

I have a class like this

public class test{
        public string a { get; set; }
        public string b { get; set; }
}

and a list of objects

List<test> list= new List<test>();
list.Add(new test() {a = "1a", b = "1b" });
list.Add(new test() {a = "2a", b = "2b" });
...

i want concatenate the elements and have a string like

"1a 1b + 2a 2b" ... etc

Can i use Linq to do this?

This can be done in Linq by mapping to a string as follows.

string Result =
    String.Join(" + ", 
        list.Select(iObj => String.Format("{0} {1}", iObj.a, iObj.b)));

String.Join(" + ", list.Select(x => /*What you want*/));

will do the trick!
