What are some good alternatives to multiple-inheritance in .NET?

Question

I\'ve run into a bit of a problem with my class hierarchy, in a WPF application. It\'s one of those issues where you have two inheritance trees merging together, and you can

Answer 1

I think is a one of solution.

public interface IClassA
{
    void Foo1();
    void Foo2();
}

public interface IClassB
{
    void Foo3();
    void Foo4();
}

public class ClassA :IClassA
{
    #region IClassA Members

    public void Foo1()
    {
    }

    public void Foo2()
    {
    }

    #endregion
}

public class ClassB :IClassB
{
    #region IClassB Members

    public void Foo3()
    {
    }

    public void Foo4()
    {
    }

    #endregion
}

public class MultipleInheritance :IClassA, IClassB
{
    private IClassA _classA;
    private IClassB _classB;

    public MultipleInheritance(IClassA classA, IClassB classB)
    {
        _classA = classA;
        _classB = classB;
    }

    public void Foo1()
    {
        _classA.Foo1();
    }

    public void Foo2()
    {
        _classA.Foo2();
        AddedBehavior1();
    }

    public void Foo3()
    {
        _classB.Foo3();
        AddedBehavior2();
    }

    public void Foo4()
    {
        _classB.Foo4();
    }

    private void AddedBehavior1()
    {

    }

    private void AddedBehavior2()
    {

    }
}

Class MultipleInheritance add new behavior to two different object without affecting the behavior of this objects. MultipleInheritance have the same behaviors as delivered objects (Inherits both behaviors).
