I want to have something like:

class Main{
   SomeClass[] classArray = new SomeClass[199];   // Problem --> All elements are null
   for(int i=0; i<classArray.Length; i++){
      classArray[i] = new SomeClass();
   }
}

class SomeClass{
   int x = 1;
   public SomeClass(){}
}

but without loop and without doing something like:

SomeClass[] classArray = new SomeClass[] {new SomeClass(), new SomeClass(), ...}

Is this possible?

    Consider using List<T>. Commented Dec 12, 2016 at 20:07

    With using List<T> i also have to use a loop to add a fixed number of elements or am i wrong? Commented Dec 12, 2016 at 20:13

Enumerable.Range method will generate collection of integers in the given range.
Select method will create new instance for every number.
ToArray will enumerate generated collection and create an array

var yourArray = Enumerable.Range(1, 199).Select(i => new SomeClass()).ToArray();

That's not really possible. You can do several things that result in loops, but don't quite look like loops. For example:

var list = Enumerable.Range(0, 199)
           .Select(_ => new SomeClass())
           .ToList();
