public class Forms
{
//Company Contact Information Customer
public string Company { get; set; }
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
[Required]
public string Email { get; set; }
[Required]
public long PhoneNumber { get; set; }
public string Comments { get; set; }
//Company Address Customer
[Required]
public string StreetAddress { get; set; }
[Required]
public string City { get; set; }
[Required]
public string State { get; set; }
[Required]
public string ZipCode { get; set; }
}
看看这个。
[HttpPost]
public IActionResult SendEmail()
{
var NewContact = new Forms();
// Existing code
}
您正在创建一个全新的类对象Forms。此新对象属性将具有默认值，而不是您发布表单中的值。
您可以做的是，向类型为 Forms 的SendEmail操作方法添加一个参数。提交表单后，DefaultModelBinder 会将表单字段映射到参数，因为属性名称与表单字段名称匹配。
[HttpPost]
public IActionResult SendEmail(Forms NewContact)
{
// Existing code which reads from NewContact object property values
}
您正在声明一个新的 Forms 对象，而不是在 post 方法中的参数中传递它。因此，这些字段都初始化为默认值。
正如 Nick 所说，您需要将模型作为参数传递给控制器方法。
在使用模型的值之前，还需要检查模型的验证状态，并且（通常）如果模型无效，则返回相同的视图，以便向用户显示验证错误。
因此，您的方法可能是这样的：
[HttpPost]
public IActionResult SendEmail(Forms NewContact)
{
if (ModelState.IsValid)
{
// model is valid, you can send email now
string body = "First Name: " + NewContact.FirstName + "'n"
+ "Last Name:" + NewContact.LastName + "'n"
+ "Company:" + NewContact.Company + "'n'n"
+ "Comments:" + NewContact.Comments;
MailMessage mailBody = new MailMessage("Something@example.com", "Somethingelse@example.com");
mailBody.Subject = "Contact Form";
mailBody.Body = body;
SmtpClient smtpClient = new SmtpClient("smtp.aol.com", 587);
smtpClient.Credentials = new NetworkCredential()
{
UserName = UserNameHidden,
Password = PasswordHidden
};
smtpClient.EnableSsl = true;
smtpClient.Send(mailBody);
return Redirect("Contact");
}
else
{
// model contains validation errors
// return the same view so form is populated with existing values,
// and validation errors are shown
//
// You are responsible for populating model values in view page
// it will be done automatically if you're using tag helpers like @Html.EditorFor()
return View("Contact", model);
}
}
此外，发送邮件可能需要一些时间，因此最好使控制器方法异步。
