c# - 从部分视图发布表单时返回的内容

Question

我是 MVC 新手，正在尝试实现联系页面。我为联系人部分创建了一个部分视图，并在我的索引页面上添加了这一行

@Html.Partial("_Contact")

当我的表单提交时，我的代码将执行，当表单无效时，我必须返回一些东西。我的问题是我必须返回什么才能使其正常工作。我想将我的模型返回到我的联系人部分视图，但我仍然必须显示我的索引页面，因为联系人部分显示在那里。还是我看错了？

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";
}

<form asp-controller="Home" asp-action="_Contact" method="post" class="form-horizontal" role="form">

    <!-- Contact Page Section Start -->
