Question

I am looking at better way of writing following code using linq/lambda expression..

I am trying to form a string from list. I have function that convert t to string. So what i want is have a string from list.

Here is pseudo code:

  string strTemp;

  foreach (SearchTerm s in terms)
  {
    strTemp +=  string.Format(" and {0} ", s.CreateToString());
  }

where terms is list<searchTerms>.

Answer 1

Like this:

string temp = String.Join(" and ", terms.Select(s => s.CreateString()));

If you’re not using .Net 4.0, you’ll need to add .ToArray().

If you’re calling the ToString method on each term (as opposed to a different method) and you are using .Net 4.0, you can simply write

string temp = String.Join(" and ", terms);
