我是MVC的新手，正在尝试建立联系页面。 我为接触部分创建了局部视图，并使用此行将其添加到索引页面上
@Html.Partial("_Contact")
提交表单后，我的代码将执行，而表单无效时，我必须返回一些内容。 我的问题是我必须返回什么才能使其正常工作。 我想将模型返回到我的联系人局部视图，但是我仍然必须显示我的索引页面，因为那里显示了联系人部分。 还是我看错了方向？
这是邮政编码：
[ValidateAntiForgeryToken]
public IActionResult _Contact(EmailFormModel model)
{
if (ModelState.IsValid)
{
var path = _hostingEnvironment.WebRootPath;
string html = System.IO.File.ReadAllText(path);
var message = new MailMessage();
var templatePath = path + _configuration.GetSection("Email.PathToHtmlTemplate").Value;
var smtpHost = _configuration.GetSection("Email.Smtp.Host").Value;
var smtpPort = Convert.ToInt32(_configuration.GetSection("Email.Smtp.Port").Value);
var smtpUser = _configuration.GetSection("Email.Smtp.UserName").Value;
var smtpPass = _configuration.GetSection("Email.Smtp.Password").Value;
var from = _configuration.GetSection("Email.From").Value;
var to = _configuration.GetSection("Email.To").Value;
var cc = _configuration.GetSection("Email.Cc").Value;
var bcc = _configuration.GetSection("Email.Bcc").Value;
var subject = _configuration.GetSection("Email.Subject").Value;
var dic = new Dictionary<string, string>()
{
{ "{{NAME}}", model.Name },
{ "{{TEL}}", model.Telephone },
{ "{{EMAIL}}", model.Email },
{ "{{MESSAGE}}", model.Message },
};
dic.ForEach(x => html = html.Replace(x.Key, x.Value));
foreach (var t in to.Split(';'))
{
message.To.Add(new MailAddress(t));
}
foreach (var t in cc.Split(';'))
{
message.CC.Add(new MailAddress(t));
}
foreach (var t in bcc.Split(';'))
{
message.Bcc.Add(new MailAddress(t));
}
message.From = new MailAddress(from);
message.Subject = subject;
message.Body = html;
message.IsBodyHtml = true;
using (var smtp = new SmtpClient())
{
var credential = new NetworkCredential
{
UserName = smtpUser,
Password = smtpPass
};
smtp.Credentials = credential;
smtp.Host = smtpHost;
smtp.Port = smtpPort;
smtp.Send(message);
return View("EmailSent");
}
}
return View(model);
}
索引视图：
@{
ViewData["Title"] = "Home Page";
}
...
@Html.Partial("_Contact")
联系人视图：
@model EmailFormModel;
@{
ViewData["Title"] = "Contact";
}
