C# .NET - Rational numbers overloaded operator - error

Hi,

I need to add 2 rational numbers by overloading the + operator. I have the rational class that has a constructor that takes in the integral portion, numerator and denominator portion.  

I am getting an error Rational does not contain a constructor that takes in 2 arguments. How can i resolve it.

The ouput should be in the form of a fraction. Can someone tell me what is the mistake that i am doing and how to fix it please.

Class Rational

{

#region Private Data Members

private int _integral;

private int _num;

private int _den;

#region Public Properties

public int Integral

{get{return _integral;}

set{_integral = value;}}

private int Num

{get {return _num;}

set {_num = value;}}

public int Den

{get {return _den;}

set {_den = value;}}

#region Constructor

public Rational(int integ, int num, int den)

this.Integral = integ;

this.Num = (den * integ)+ num;

this.Den = den;

//overload opertor +

public static Rational operator +(Rational a, Rational b)

return new Rational(a.Num * b.Den + b.Num * a.Den, a.Den * b.Den);

}

MAIN PROGRAM

static void Main(string[] args)

Rational a = new Rational(1, 1, 2);

Rational b = new Rational(1, 1, 2);

Console.WriteLine(a + b);

Console.ReadKey();

The problem is on the following line in your code:

return new Rational(a.Num * b.Den + b.Num * a.Den, a.Den * b.Den);

You are only passing 2 parameters to the constructor.  I believe this should be as follows:

return new Rational(a.Integral + b.Integral, a.Num * b.Den + b.Num * a.Den, a.Den * b.Den);
