JavaScript spread syntax in C#

Question

Is there any implementation in C# like JavaScript\'s spread syntax?

var arr = new []{
   \"1\",
   \"2\"//...
};

Console.WriteLine(...arr);

Answer 1

you can also do the following

    var a  = new List(new int[]{1,2,3}){5};
    Console.WriteLine(a.Count);

will print 4

if you want to achieve initialization of lists or arrays with both an accompanying enumerable and parameters
