我不明白为什么我没有得到数据时，开始DeletePost行动方法，我得到了日期在删除方法，但没有得到在DeletePost有人能解释吗？

//Get - Delete
public IActionResult Delete(int? id)
{
    if (id == null || id == 0)
    {
        return NotFound();
    }
    var obj = _db.Event.Find(id);
    if (obj == null)
    {
        return NotFound();
    }
    return View(obj);
}

//Post - Delete
[HttpPost]
[ValidateAntiForgeryToken]
public IActionResult DeletePost(int? id)
{
    var obj = _db.Event.Find(id);

    if (obj == null)
    {
        return NotFound();
    }
    _db.Event.Remove(obj);
    _db.SaveChanges();
    return RedirectToAction("Index");
}

这里是删除视图，我发送请求到DeletePost，不要不如果它帮助一些如何。但mby它帮助一些如何。我得到后的方法，并得到asp-action删除视图
