Is it possible to find object's class in the list of objects?

Question

I've got a list of objects = { obj1,obj2,obj3 }

Every class of the objects is inherited from the same interface

interface IObjects
class Obj1:IObjects
class Obj2:IObjects
class Obj3:IObjects

And I want to find object of Obj1 class for examp. How to do it?

You can do so by:

var listOfObject1s = objects.Where(o => o is Obj1).ToList();

if(obj.GetType() == typeof(Obj1))
{
    // obj is an Obj1!
}

Linq method:

IObjects[] objList = new IObjects[] { obj1,obj2,obj3 };
obj1 o1 = objList.Where(o => o.GetType() = typeof(Obj1)).First();
