If an interface inherits IEquatable the implementing class can define the behavior of the Equals method. Is it possible to define the behavior of == operations?

public interface IFoo : IEquatable  
{}  

public class Foo : IFoo  
{  
    // IEquatable.Equals  
    public bool Equals(IFoo other)  
    {  
        // Compare by value here...
    }  
}

To check that two IFoo references are equal by comparing their values:

IFoo X = new Foo();  
IFoo Y = new Foo();
  
if (X.Equals(Y))  
{  
     // Do something  
}

Is it possible to make if (X == Y) use the Equals method on Foo?
