Dependency and parameter to constructor

Question

I have:

[Dependency]
public qwe property { get; set; }

And:

class qwe
{
    public qwe()
    {
        MessageBox.Show("qwe");
    }

    public qwe(int x)
    {
        MessageBox.Show("qwe INT");
    }  
}

How can I configure Unity so that when I have registered an int Unity creates my class qwe with the constructor that takes an int, but when I haven't registered an int value, Unity uses the constructor with zero parameters.

You can either configure Unity to use the default constructor, the constructor that takes an integer parameter or declare a factory function that does that.

Default c'tor:

container.RegisterType<qwe>(new InjectionConstructor());

c'tor with integer parameter:

container.RegisterType<qwe>(new InjectionConstructor(myIntValue));

Factory:

container.RegisterType<qwe>(new InjectionFactory(c => (myIntValue > 0) ? new qwe(myIntValue) : new qwe()));
