C# Unit Test Visual Studio 2013 Test Failed

I wrote a class Complex and class for unit tests. When the + operator performs tests crashes my error. Why?

Complex:

    private double re,im;

    public Complex(double re = 0.0, double im = 0.0)
    {
        this.re = re;
        this.im = im;
    }

    public static Complex operator +(Complex C1, Complex C2)
    {

        return new Complex(C1.re+C2.re,C1.im+C2.im);
    }

Unit test:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    public void ComplexPlus()
    {
        Complex c1 = new Complex(4.6, 1.6), c2 = new Complex(6.63, 2.67);
        Complex c3 = c1 + c2;
        Complex c4 =  new Complex(11.23, 4.27);
        Assert.AreEqual(c3,c4 );
    }
}

It's look your declared the same class in 2 projects. Delete one and add reference from one project to other (add reference to base project to test project).

The problem is that you are call AreEqual to the both classes Complex. You should check if their properties are equal !

Here is the code which you need.

Assert.AreEqual(c3.Re,c4.Re);
Assert.AreEqual(c3.Im,c4.Im);

EDIT: Add properties

private double _re, _im;

public Complex(double re = 0.0, double im = 0.0)
{
    _re = re;
    _im = im;
}

public double Re
{
     get { return _re; }
     set { _re = value; }//or just get !
}

public double Im
{
     get { return _re; }
     set { _re = value; }//or just get !
}

And the check will be this.

Assert.AreEqual(c3.Re,c4.Re);
Assert.AreEqual(c3.Im,c4.Im);
