我对着提交在ASP.NET核心2.2.1 MVC一个形式的问题。我意识到，当我点击提交按钮的形式不提交。我已经证实，确认标记是存在的，我已经表明了操作路径。
我生成从一个视图模型的形式。这里低于视图模型
public class SignUpViewModel
{
[Required]
public string Surname { get; set; }
[Required,Display(Name ="Other Names")]
public string Othernames { get; set; }
[EmailAddress,Required,Display(Name ="Email Address")]
public string EmailAddress { get; set; }
[Display(Name ="Phone Number"),DataType(DataType.PhoneNumber),MinLength(11,ErrorMessage ="Phone number should be a valid GSM Mobile number"),Required]
public string PhoneNumber { get; set; }
[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }
public Gender Gender { get; set; }
[Display(Name ="State of Residence"),Required]
public int? ResidenceState { get; set; }
[Display(Name ="Local Government of Residence")]
public int? ResidenceLga { get; set; }
[Display(Name ="Date of Birth"),DataType(DataType.Date)]
public DateTime? DateOfBirth { get; set; }
}
形式是这里
<form asp-action="signup" method="POST">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label asp-for="Surname" class="control-label"></label>

</div>
<div class="form-group">
<label asp-for="Othernames" class="control-label"></label>
<input asp-for="Othernames" class="form-control" />
<span asp-validation-for="Othernames" class="text-danger">
</span>
</div>
<div class="form-group">
<label asp-for="EmailAddress" class="control-label"></label>
<input asp-for="EmailAddress" class="form-control" />
<span asp-validation-for="EmailAddress" class="text-danger"></span>

<div class="form-group">

<select asp-for="Gender" class="form-control" asp-
items="@Html.GetEnumSelectList<Gender>()">
<option selected="selected" value="">--Select--</option>
</select>
<span asp-validation-for="Gender" class="text-danger"></span>
</div>
<div class="form-group">
<label asp-for="ResidenceState" class="control-label"></label>
<select asp-for="ResidenceState" class="form-control" asp-
items="ViewBag.StateId">
<option value="">-Select-</option>
</select>
<span asp-validation-for="ResidenceState" class="text-danger">
</span>
</div>
<div class="form-group">
<label asp-for="ResidenceLga" class="control-label"></label>
<select asp-for="ResidenceLga" class="form-control"><option
value="">-Select State First-</option></select>
<span asp-validation-for="ResidenceLga" class="text-danger">

<div class="form-group">
<label asp-for="DateOfBirth" class="control-label"></label>
<input asp-for="DateOfBirth" class="form-control" />

</span>
</div>
<div class="form-group">
<input type="submit" value="Register" class="btn btn-primary" />
</div>
</form>
所述控制器被如下：
public IActionResult Signup()
{
ViewData["StateId"] = new SelectList(_context.States, "Id", "Name");
return View();
}
[HttpPost]
//[ValidateAntiForgeryToken]
public async Task<ActionResult> Signup(SignUpViewModel model)
{
if (EmailExists(model.EmailAddress))
{
ModelState.AddModelError("", "This email address is already registered with us.");
}
if (ModelState.IsValid)
{
try
{
Enrollee enrollee = new Enrollee {
Surname=model.Surname,
OtherNames=model.Othernames,
Email=model.EmailAddress,
Gender=model.Gender,
StateId=model.ResidenceState,
LgaId=model.ResidenceLga,
DateOfBirth=model.DateOfBirth
};
var result = await _userManager.CreateAsync(enrollee, model.Password);
if (result.Succeeded)
{
//send password the new staff's email
var body = "<p>Email From {0} ({1})</p><p>Message:</p><p>{2}</p>";
var baseurl = $"{Request.Scheme}://{Request.Host}{Request.PathBase}";
var loginurl = baseurl + "/User/Login";
var msg = "Congratulations! " + model.Othernames + "," + "<br />" + "You have just been registered on the eSchool portal." + "<br />" + "Use this email as your login username and the password you registered with to login to the portal:" + "<br />" + "<br />" + "Click <strong><a href='" + loginurl + "'>here</a></strong> to login" + "\r" + "\r";
var message = string.Format(body, "eSchool Portal", "[email protected]", msg);
await _emailSender.SendEmailAsync(model.EmailAddress, "Registration on eSchool portal", message);
return RedirectToAction(nameof(Signup));
}
foreach (var error in result.Errors)
{
ModelState.AddModelError(string.Empty,
error.Description);
}
}
catch (Exception e)
{
ModelState.AddModelError("",e.Message.ToString());
}
}
else
{
ModelState.AddModelError(string.Empty, "Something went wrong
with the process. Please retry");
}
return RedirectToAction(nameof(Signup));
}
我会感谢任何指导，以使错误的形式不提交。
谢谢
在你[HttpPost] Signup(...)动作你总是返回RedirectToAction(nameof(Signup))这将导致你与一个空白表格回在同一页上结束
