Help C# "this keyword"

Question

The this Keyword

The program you are given takes 2 numbers as input and should calculate and output their average. But something is wrong.
Complete the Avg class by creating the constructor, where the 2 parameters will be assigned to members of the class.

Sample Input
5.0
4.0

Sample Output
4.5
Inside the constructor, use this keyword with class members for assignation.
my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
double num1 = Convert.ToDouble(Console.ReadLine());
double num2 = Convert.ToDouble(Console.ReadLine());

Avg avg = new Avg(num1, num2);

Console.WriteLine(avg.GetAvg());
}
}

class Avg
{
double num1;
double num2;

//create the constructor
public Con(double num1, double num2)
{
this.num1 = num1;
this.num2 = num2;
}

public double GetAvg()
{
return (num1 + num2)/2;
}
}
}
this code isn't working please help.

Answer 1

The constructor should have the same name as the class. Rename Con() to Avg(). Then your program will compile and run correctly.

Answer 4

I think this is the best solution and the easiest one
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.CompilerServices;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
double num1 = Convert.ToDouble(Console.ReadLine());
double num2 = Convert.ToDouble(Console.ReadLine());

Avg avg = new Avg(num1, num2);

Console.WriteLine(avg.GetAvg());
}
}

class Avg
{
double num1;
double num2;

//create the constructor
public Avg( double num1,double num2){
this.num1=num1;
this.num2=num2;
}

public double GetAvg()
{
return (num1 + num2)/2;
}
}
}

using System.Threading.Tasks;

namespace SoloLearn

Avg avg = new Avg(num1, num2);

Console.WriteLine(avg.GetAvg());
}
}

class Avg
{
readonly double num1;
readonly double num2;

//create the constructor
public Avg(double num1, double num2)
{
this.num1 = num1;
this.num2 = num2;
}

public double GetAvg()
{
return (num1 + num2)/2;
}
}
