Question

当我按保存按钮时，所有字段{email，name ..}都为空为什么代码不起作用。只需要从html文本框中获取数据并使用控制器块中的值。

 @model RenderCshtml.Models.ContactModel

            ViewBag.Title = "Contact";

            </div>

控制器：----

  public ActionResult Contact()
        {       
            return View(new ContactModel());
        }
        [HttpPost]
        public ActionResult Contact(ContactModel vm)
        {
            if (ModelState.IsValid)
            {

                {
                    MailMessage msz = new MailMessage();
                    msz.From = new MailAddress(vm.Email);//Email which you are getting 
                                                         //from contact us page 
                    msz.To.Add("dinesh.joshi1794@gmail.com");//Where mail will be sent 
                    msz.Subject = vm.Subject;
                    msz.Body = vm.Message;
                    SmtpClient smtp = new SmtpClient();

                    smtp.Host = "smtp.gmail.com";

                    smtp.Port = 587;

                    smtp.Credentials = new System.Net.NetworkCredential
                    ("securedj94@gmail.com", "!l0veum0m");

                    smtp.EnableSsl = true;

                    smtp.Send(msz);

                    ModelState.Clear();
                    ViewBag.Message = "Thank you for Contacting us ";
                }
                catch (Exception ex)
                {
                    ModelState.Clear();
                    ViewBag.Message = $" Sorry we are facing Problem here {ex.Message}";
                }
            }
            return View();
        }

型号：------

 public class ContactModel
{


    public string Name { get; set; }    

    public string Email { get; set; }

    public string Subject { get; set; }

    public string Message { get; set; }       

}

Answer 1

如果您使用的是asp.net mvc4或更高版本，这可能会对您有用，但是您没有指定您使用的版本，所以如果它有帮助就会发布它

而不是像这样使用输入：

<input asp-for="Name" class="form-control"/>

您可以使用textboxfor，因为它将链接到模型并发布到控制器

这是一个文本框的例子，用于输入你的名字，你可以为其他人做同样的事情

@Html.TextBoxfor(m => n.Name, new { @class = "form-control" })

数据没有移动视图到控制器，我尝试了所有可能的解决方案
