Solution 1

interface IThing { int DoStuff(); }
class Thing: IThing { public int DoStuff(){ return 42; } }

void UnityTest(){
 // Here's how you register
 unityContainer.RegisterType<IThing, Thing>();

 // ... and here's how you resolve
 IThing thing = unityContainer.Resolve<IThing>();
 
 int answer = thing.DoStuff(); // will be 42
}

I'm sure Google could have found you that. Please put a bit of effort in before asking on here.

thanks for ur code snippet...actually i want to know what is the purpose of using unity container...in simple words...what is the advantage of this concept...as u said i can get this in google...but the real concept is where i can learn from seniors like you...pls correct me if im wrong...
Just want to know the advantage of using this design pattern(Ioc)...and how does it makes difference from normal approach...

What it gives you is that you can change registrations at runtime, so you can get an IThing which is appropriate to the current context. It is commonly used for modular applications to get information providers for display regions, menus, statusbars etc. I am not an expert, though (just happen to be using Unity on a project right now).
