Way to stor diferrent type of object c#?

There is, you just need to sort the syntax out.
First you need this line in your code file:

using System.Collections.Generic;

Then you can declare your collection:

var foo = new List<int>(); //List of integers
var bar = new Dictionary<string,int>();// A dictionary of bools, using a string as a key
var baz= new Queue<myclass>(); // A queue of objects of type myClass

etc...

The List<T> and List(T) you see on MSDN are really there to allow developers know the type is generic (the T part is the generic that needs to be specified, and is specified in different ways in the various languages supported). This is confusing when you are first getting started....
