1,228 PointsNo matter what I do, I keep getting Did you convert the property to a single-lined, expression bodied property? error
I must be blind here, because no matter what I do, I can't seem to get pass the challenge. I Literally converted(?) all the Expressions into single-lined, expression bodied property based on the Expression Bodied Members video. but I still get the error.
Also I get a compiling error when I remove the '()' from public double Area() => SideLength * SideLength;
I can't seem to get a good answer on what I'm doing wrong here.
help?
namespace Treehouse.CodeChallenges
{
class Square : Polygon
{
public double SideLength { get; private set; }
public double Area() => SideLength * SideLength;
public Square(double sideLength) : base(4) => SideLength = sideLength;
public void Scale(double factor) => SideLength *= factor;
}
}
namespace Treehouse.CodeChallenges
{
class Polygon
{
public int NumSides { get; private set; }
public Polygon(int numSides) => NumSides = numSides;
}
}

Your code is correct, however the treehouse compiler is failing because it did not ask you to change the polygon.cs as well as did not ask you to change the square method.
If you revert these back you will pass.
namespace Treehouse.CodeChallenges
{
class Square : Polygon
{
public double SideLength { get; private set; }
public double Area => SideLength * SideLength;
public Square(double sideLength) : base(4)
{
SideLength = sideLength;
}
public void Scale(double factor) => SideLength *= factor;
}
}

One thing which may be helpful is checking out the different operators
Good Luck!

Well this is embarrassing! I re-read the instructions for the challenge, and now I see what I was supposed to do.
Thought I was supposed to convert all of Square.cs into a single line property.
I guess I was not at %100 when I was doing the challenge at the time.
Live and learn in this case.
By the way, would this:
public Square(double sideLength) : base(4) => SideLength = sideLength;Be valid normally? I didn't see an error in the preview, so I was just wondering.
