MVC - post视图模型没有被填充
本文关键字：填充 模型 post 视图 MVC | 更新日期: 2023-09-27 18:01:51
操作方法:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Register(RegisterViewModel blahblah)
{
HttpPostedFileBase uploadFile;
if (ModelState.IsValid)

public class RegisterViewModel
{
public string Title;
public string FirstName;
public string LastName;
public string Address;
public string Suburb;
public string HomePhone;
public string Mobile;
public string Email;
public string EmergencyContactName;
public string EmergencyContactRelation;
public string EmergencyContactPhone;
public string EmergencyContactEmail;
public string DrivingLicenceNo;
// [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
public DateTime DrivingLicenceExpiryDate;
public string DrivingLicenceImage;
// [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString ="{0:yyyy-MM-dd}")]
public DateTime DateofBirth;
public string Notes;
public string NextAppointment;
public string Name
{
get
{
return $"{FirstName} {LastName}";
}
}
}
viewmodel on post全部为空。如果我使用实体框架生成的tblPersonalDetail模型类，然后更改视图中的引用(Register.cshtml)，它将与数据一起发布。但是对于自定义视图模型不是这样。——Register.cshtml
@model Leo.ViewModel.RegisterViewModel
@{
ViewBag.Title = "Register New User";

如果您有字段而不是属性，则需要更改视图模型定义以拥有如下属性:
public class RegisterViewModel
{
public string Title { get; set;}
public string FirstName { get; set;}
//............
//............
}
ASP中默认的模型绑定器。. NET MVC将只绑定到可公开访问的属性，但你目前使用的是字段，这将不会被绑定。
你只需要用必要的getter/setter来修饰它们，如下所示，使它们成为属性:
public class RegisterViewModel
{
public string Title { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
// Others omitted for brevity
}
