问题： 我已经创建了一个自定义配置文件对象，正如 Joel在这里所描述的那样。然后，我使用 Jeremy 的方法（此处）扩展自定义配置文件以允许我使用生成用户并设置这些值。然后我创建了一个 ViewModel 来显示会员信息和个人资料信息，以便用户可以更新他们的会员信息（电子邮件）和个人资料信息。**视图显示我在视图中的更新信息中输入的所有字段，然后单击保存，出现以下错误
System.Configuration.SettingsPropertyNotFoundException：未找到设置属性“FirstName”。**
这是我的自定义配置文件对象（模型）：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Profile;
using System.Web.Security;
namespace NDAC.Models
{
public class ProfileInformation : ProfileBase
{
static public ProfileInformation CurrentUser
{
get
{
if (Membership.GetUser() != null)
{
return (ProfileInformation)(ProfileBase.Create(Membership.GetUser().UserName));
}
else
{
return null;
}
}
}
public virtual string FirstName {
get
{
return ((string)(base["FirstName"]));
}
set
{
base["FirstName"] = value; Save();
}
}
public virtual string LastName {
get
{
return ((string)(base["LastName"]));
}
set
{
base["LastName"] = value; Save();
}
}
public string Street
{
get
{
return ((string)(base["Street"]));
}
set
{
base["Street"] = value; Save();
}
}
public string Street2
{
get
{
return ((string)(base["Street2"]));
}
set
{
base["Street2"] = value; Save();
}
}
public string City
{
get
{
return ((string)(base["City"]));
}
set
{
base["City"] = value; Save();
}
}
public string State
{
get
{
return ((string)(base["State"]));
}
set
{
base["State"] = value; Save();
}
}
public string ZipCode
{
get
{
return ((string)(base["ZipCode"]));
}
set
{
base["ZipCode"] = value; Save();
}
}
public string PhoneNumber
{
get
{
return ((string)(base["PhoneNumber"]));
}
set
{
base["PhoneNumber"] = value; Save();
}
}
public string SemesterID
{
get
{
return ((string)(base["SemesterID"]));
}
set
{
base["SemesterID"] = value; Save();
}
}
static public ProfileInformation GetProfile(string username)
{
return Create(username) as ProfileInformation;
}
internal static ProfileInformation NewUser
{
get { return System.Web.HttpContext.Current.Profile as ProfileInformation; }
}
}
}
这是 UserProfile 获取方法：
[Authorize]
public ActionResult UserProfile()
{
string id = User.Identity.Name.ToString();
MembershipUser user = Membership.GetUser(id);
var model = new UserViewModel();
UserInformation userInf = new UserInformation();
userInf.Username = user.UserName;
userInf.Email = user.Email;
ProfileInformation currentProfile = ProfileInformation.GetProfile(user.UserName);
model.Profile = currentProfile;
model.UserInf = userInf;
return View(model);
}
如您所见，我正在使用视图模型来显示视图。视图模型是这样的：
public class UserViewModel
{
public UserInformation UserInf{ get; set; }
public ProfileInformation Profile { get; set; }
}
最后更新 UserProfile 的 HttpPost 方法是：
[Authorize]
[HttpPost]
public ActionResult UserProfile(UserViewModel model)
{
ProfileInformation currentProfile = ProfileInformation.GetProfile(User.Identity.Name.ToString());
ProfileInformation.CurrentUser.FirstName = model.Profile.FirstName;
currentProfile.LastName = model.Profile.LastName;
currentProfile.Street = model.Profile.Street;
currentProfile.Street2 = model.Profile.Street2;
currentProfile.City = model.Profile.City;
currentProfile.State= model.Profile.State;
currentProfile.ZipCode = model.Profile.ZipCode;
currentProfile.PhoneNumber = model.Profile.PhoneNumber;
currentProfile.Save();
MembershipUser user = Membership.GetUser(User.Identity.Name.ToString());
user.Email = model.UserInf.Email;
Membership.UpdateUser(user);
TempData["SuccessMessage"] = "Your Profile information has been saved";
ViewBag.Title = "My Profile";
return RedirectToAction("ProfileUpdated");
}
问题是我无法弄清楚错误来自哪里。表单呈现我输入有效信息，然后我被告知“未找到设置属性 'FirstName'。” 就像 UserViewModel 正在尝试更新 ProfileInformation.cs （自定义配置文件对象），但它说它找不到对象......我想这是因为它没有要更新的配置文件......但我在发布之前无法解决错误……太令人沮丧了！任何帮助将不胜感激！！！感谢您抽出宝贵时间查看此内容。
我还将向您介绍我的 Register 方法，该方法成功地使用了自定义 Profile 对象，甚至将 name 属性更新为“ScoobyDoo”以进行测试:)
[HttpPost]
public ActionResult Register(RegisterModel model)
{
if (ModelState.IsValid)
{
// Attempt to register the user
MembershipCreateStatus createStatus = MembershipService.CreateUser(model.UserName, model.Password, model.Email, model.SecretQuestion, model.SecretAnswer);
if (createStatus == MembershipCreateStatus.Success)
{
FormsService.SignIn(model.UserName, false /* createPersistentCookie */);
Roles.AddUserToRole(model.UserName, "Student");
ProfileInformation.NewUser.Initialize(model.UserName, true);
ProfileInformation.NewUser.Save();
string currentSemesterID = CurrentSemester;
ProfileInformation profile = ProfileInformation.GetProfile(model.UserName);
profile.SemesterID = currentSemesterID;
profile.FirstName = "ScoobyDoo";
return RedirectToAction("Index", "Home");
}
else
{
ModelState.AddModelError("", AccountValidation.ErrorCodeToString(createStatus));
}
}
// If we got this far, something failed, redisplay form
ViewBag.PasswordLength = MembershipService.MinPasswordLength;
return View(model);
}
