Question

var a = new []{"a"};
var b = new []{"b"};
var c = new []{"c"};

Is it possible to declare / initialise a generic list, providing the three collections above in one line?

var l = new List<string>(a); //fine for one
var l2 = new List<string>(new[] { a, b, c }.SelectMany(x => x)); //this will work but its horrible!

Answer 1

How about:

var list = a.Concat(b).Concat(c).ToList();
