Question

Please consider the following code :

string[] words =
{ "Too", "much", "of", "anything", "is" ,"good","for","nothing"};

var groups =from word in words
            orderby word ascending
            group word by word.Length into lengthGroups
            orderby lengthGroups.Key descending
           select new {Length=lengthGroups.Key, Words=lengthGroups};

   foreach (var group in groups)
   {
     Console.WriteLine("Words of length " + group.Length);
     foreach (string word in group.Words)
     Console.WriteLine(" " + word);
   }

Why do we need the keyword “new” here?.can you give some other simple example to understand it properly?

Answer 1

The new keyword is used to create an instance of a class.

In this case it’s an anonymous class. You can use the same syntax to create an anonmyous object outside the scope of a LINQ query:

object o = new { Name = "Göran" };
