how to add ith item from one List to another

Suppose I have 2 lists:

List<string> CharactersInStringEnteredByUser = new List<string>();
List<string> CharactersInAutomaticallyGeneratedString = new List<string>();

while (CharactersInStringEnteredByUser.Count < 25)
{
    CharactersInStringEnteredByUser.Add(????);
}

I want to add ith item from CharactersInAutomaticallyGeneratedString to CharactersInStringEnteredByUser.

*Update: *

Let me clarify my question.

I want to check if CharactersInStringEnteredByUser < 25 ? If so then add first item from CharactersInAutomaticallyGeneratedString.

Now again check if CharactersInStringEnteredByUser < 25 ? If so then add second item from CharactersInAutomaticallyGeneratedString.

And so on......

Probably you want to take first 25 values from first list and save them into second. So you can do this

CharactersInStringEnteredByUser = CharactersInAutomaticallyGeneratedString.Take(25).ToList();

If your list may be already filled (as you are checking its count) then you can do this.

int count = CharactersInStringEnteredByUser.Count;
if(count < 25)
  CharactersInStringEnteredByUser = CharactersInAutomaticallyGeneratedString.Take(25-count).ToList();

List<string> CharactersInStringEnteredByUser = new List<string>();
List<string> CharactersInAutomaticallyGeneratedString = new List<string>();

int i = 0;
while (CharactersInStringEnteredByUser.Count < 25)
{
    CharactersInStringEnteredByUser.Add(CharactersInAutomaticallyGeneratedString[i]);
    i++;
}

You should also verify that CharactersInAutomaticallyGeneratedString has enough items. I would add a check in the loop's body.

The final code can be:

int i = 0;
while (CharactersInStringEnteredByUser.Count < 25)
{
    if (i >= CharactersInAutomaticallyGeneratedString.Count)
        break;

    CharactersInStringEnteredByUser.Add(CharactersInAutomaticallyGeneratedString[i]);
    i++;
}
