A couple of points here: you can just grab the instance from the session as a list and keep a reference to it, then you can check it is something (not null) and that it contains something which is also something (if nullable), before grabbing a reference of that and performing desired actions:

var fruitList = Session["listSession"] as List<Fruit>;
if (fruitList != null && fruitList.Count > 0) 
{
    var fruit = fruitList[0];
    if (fruit != null && fruit.name == "apple ")
    { 
        fruit.Consume();
    }
}

That ought to help, though I'm sure you'll need to build on it to further your purpose.

List<Fruit> fruits = Session["listSession"] as List<Fruit>;
if(fruits != null)
{
    foreach(Fruit fruit in fruits)
    {
        if(fruit.name=="apple")
            fruit.Method();
        else
            //do something else
    }
}
