我已經(jīng)成功創(chuàng)建了一個(gè)視圖來(lái)顯示一些投票記錄。但在同一個(gè)視圖上，我嘗試調(diào)用控制器上的另一個(gè)方法來(lái)導(dǎo)出這些記錄，但它只接收 0 作為參數(shù)。這是我的模型。public class Vote    {        public int Id { get; set; }        public int CPF { get; set; }        public virtual Candidate Candidate { get; set; }        public int CandidateID { get; set; }        public DateTime Moment { get; set; }}這是我的索引。public async Task<IActionResult> Index()        {            var context = _context.Vote.Include(v => v.Candidate).Include(v => v.Candidate.Election);            //This is going to be on the view for the user to select the year to export data            ViewData["Election"] = new SelectList(_context.Election, "Id", "Year");            return View(await context.ToListAsync());        }這就是我試圖呼吁的行動(dòng)。[HttpPost]public IActionResult Export(int electionYear)這是我用來(lái)發(fā)布到控制器的表單。@model IEnumerable<Models.Vote>...//Here i show the votes and then below i show this form with the Elections<form asp-action="Export">    <div class="form-group">        <select class="form-control" asp-items="ViewBag.Election"></select>    </div>    <div class="form-group">        <input type="submit" value="Exportar" class="btn btn-default" />    </div></form>我用 [FormBody] 嘗試過(guò)，它給了我 415 錯(cuò)誤
