How does Unity.Resolve know which constructor to use?
- by stiank81
Given a class with several constructors - how can I tell Resolve which constructor to use?
Consider the following example class:
public class Foo
{
public Foo() { }
public Foo(IBar bar)
{
Bar = bar;
}
public Foo(string name, IBar bar)
{
Bar = bar;
Name = name;
}
public IBar Bar { get; set; }
public string Name { get; set; }
}
If I want to create an object of type Foo using Resolve how will Resolve know which constructor to use? And how can I tell it to use the right one? Let's say I have a container with an IBar registered - will it understand that it should favor the constructor taking IBar? And if I specify a string too - will it use the (string, IBar) constructor?
Foo foo = unityContainer.Resolve<Foo>();
And please ignore the fact that it would probably be easier if the class just had a single constructor...
