CodePudding user response：

You can try to replace asp-for with id and name,asp-for will set the value of textarea with AnswerList,and then convert AnswerList to string.Here is a demo:

Action:

public IActionResult AddOrEditPoll() {
            PollViewModel model = new PollViewModel();
            model.AnswerList = new List<string> { "answer1", "answer2" , "answer3" };
            return View(model);
        }

View:

 <div >
            <label >Answer</label>
            <textarea name="AnswerList"  style="text-align:right">@string.Join("\n ", Model.AnswerList)</textarea>
        </div>

result:
