How is it "not working" exactly? Is it throwing an exception? If so, which one? We need more details to give you any help.

Can not apply indexing by [] to an expression of type "object"

So I'm guessing that second part is in a different function then?

To "object" -- you could not, but you apply to a list of objects, so it will work.

OP added a "solution" and accepted it! Why? To get reported for abuse?

Yeah, I think his really a noob, or for his/her sake so I hope. Asking questions here would only get him/her a slow learning curve, with an enormus punch to the ego. I saw your other answer (were I gave you a 5) and I agree with you.

Thank you, Kenneth.

Look, what the hell you are doing? Not only you post a comment as "solution", but you even accept this "solution" formally, with green button? Why?! Please, no abuse anymore, OK?

Are you want to write items.Add(...) or List.Add(...). o_O

Solution 1

C#

List<object> items= new List<object>();
items.Add(1);
items.Add(2);
items.Add(3);

var s = items[0];

The above works for me. Check your syntax.

Of course it should work. OP just presents a dirty question. Well, a 5.

Excuse me, who is missing what?

I caught the problem, hence the comment about syntax. ;-)

Solution 2

Of course it's working, in all senses of this word. Just try your own code, as you post it and nothing else. But why using the type object with generic collection? It makes sense to use some more concrete type.

Solution 3

Think your mistake is confusing List with item.... You adds the new variables to the list and not the item... SO yes they are right in that your syntax is wrong...

You should just take a note that the new list you created is named "item" an not "List"
