How can I get a console listing that shows the values of fields from an object IList?

Question

I have the following code:

IList<Question> oldObj = _questionService.GetQuestions(id);

The Question class has a field of QuestionId.

Can someone tell me how can I get a console list of all the QuestionIds

Answer 1

You can create a single string for the QuestionIDs separated by NewLine using string.Join and can output using Console.WriteLine

Console.WriteLine(string.Join
                        (Environment.NewLine, oldObj.Select(r=> r.QuestionId)));

For Web application/ ASP.Net:

System.Diagnostics.Debug.WriteLine(string.Join
                        (Environment.NewLine, oldObj.Select(r=> r.QuestionId)));
