The typical solution is to move the initialization code to the constructor of the class.

class MyClass
{
    Array colorValues = Enum.GetValues(typeof(ColorType));
    Array shapeValues = Enum.GetValues(typeof(ShapeType));
    Polygon[] allPolygons = new Polygon[colorValues.Length * shapeValues.Length];

    public MyClass()
    {
        int index = 0;
        foreach (ColorType color in colorValues)
        {
            foreach (ShapeType shape in shapeValues)
            {
                allPolygons[index] = new Polygon(color, shape);
                Console.WriteLine(allPolygons[index]);
                index++;
            }
        }
    }
}

static void Main(string[] args)
{
    MyClass myClass = new MyClass();
}

Should new be called (for instance in constructor) before assigning it a value?

string foo = new string();
foo = "bar";

  string foo;

  public string Foo
  {
    get { return foo; }
    set { foo= value; }
  }
...
  // in constructor
  foo = new string();

....

  class.Foo = "string";
