How do I make an if statement for when list is empty

I am trying to ask a series of random questions to the player until all are asked then end the game. I get this error when the randomly generated list is empty. I'm wondering how to make an if statement for once the list is empty. I've tried all the different variations of if list = 0 or if i or if list.Count but I have no idea what I'm doing.

Code (CSharp):

1.   List<int> list = new List<int>();   //  Declare list
2.   for (int n = 0; n < 10; n++)    //  Populate list
3.   {
4.       list.Add(n);
5.   }
6.   int index = Random.Range(0, list.Count - 1);    //  Pick random element from the list
7.   int i = list[index];    //  i = the number that was randomly picked
8.   list.RemoveAt(index);   //  Remove chosen element
9.   //  Loop lines 10-13 as many times as needed

 

You can check if the list is empty with

Code (CSharp):

1. if (list.Count == 0)

This will avoid getting an error because the random index was out of range

 

Thank you for your help. I'm using this

Code (CSharp):

1. if (list.Count == 0)
2.             {
3.                 Debug.Log("you win!");
4.             }

and I get this error

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

 

Actually I am using

Code (CSharp):

1. for (int n = 1; n < 6; n++)    //  Populate list
2.             {
3.             list.Add(n);
4.             }

so the n isn't = 0

im fiddling with it now

 

Please copy and paste the entire error message. It will include a line number in your code. It's really hard to tell what the problem is without having that line number.
