C# Course - Drawing Application Issue

Question

Im working on the Drawing application where Im working with interfaces and my answer is the code contained below:

using System;
using System.Collections.Generic;

namespace Code_Coach_Challenge
{
class Program
{
static void Main(string[] args)
{
Draw pencil = new Draw();
Draw brush = new Brush();
Draw spray = new Spray();

pencil.StartDraw();
brush.StartDraw();
spray.StartDraw();

}
}

/*
Draw => "Using pencil"
Brush => "Using brush"
Spray => "Using spray"
*/

public interface IDraw
{
void StartDraw();
}

class Draw : IDraw
{
public virtual void StartDraw()
{
Console.WriteLine("Using pencil");
}
}

//inherit this class from the class Draw
class Brush : Draw
{
//implement the StartDraw() method
public override void StartDraw(){
Console.WriteLine("Using brush");
}
}

//inherit this class from the class Draw
class Spray : Draw
{
//implement the StartDraw() method
public override void StartDraw() {
Console.WriteLine("Using Spray");
}
}
}

When I run the code It says the my output is:

Using pencil
Using brush
Using Spray

But that is wrong because the expected output is:

Using pencil
Using brush
Using spray

I cant seem to find what the issue is but I imagine that it has something to do with how my code was structured and not the actual results. Can anyone point out exactly what I'm doing wrong?

Thanks in advance!

Answer 1

Difference found only in
"Using Spray" Vs "Using spray"

expected small case s in spray.
