14,045 PointsGetting a runtime error on my Level class constructor
Hi!
I'm getting the following error:
Level.cs(9,10): error CS1520: Class, struct, or interface method must have a return type
Up to that point, my code looks like this: (Line 9 is the "public Level(Invader[] invaders)" line)
namespace TreehouseDefense
{
class level
{
private readonly Invader[] _invaders;
public Tower[] Towers { get; set; }
public Level(Invader[] invaders)
{
_invaders = invaders;
}
This looks identical to the code in the video. What am I missing?
Thanks!

231,269 PointsSince the class is named "level" (with lower-case "l"), the method "Level" (capital "L") is not recognized as a constructor; and since normal methods must have a return type this message is generated.
Always be sure the class name and constructor name(s) are exactly the same, including case.
