如何在ASP.net MVC 5應用程序上更新我的用戶帳戶數據

Question

我是新來的asp.net MVC 5身份框架，我嘗試直接更新我的詳細信息。直接轉發，我想要做的是將我的用戶信息更新到數據庫。 以前，我通過使用Migrations更改了用戶詳細信息，並使用實體框架爲了生成我的控制器，查看並自行建模。 但是，如何更新我的用戶詳細信息。我見過角色方法......但我從不明白，我該怎麼辦？沒有使用角色..因爲， 我想要更新UserManageController中所需的所有用戶信息...

可能嗎？在不同的控制器中直接在生成的用戶帳戶上獲取值？如何檢索呢？

這裏是我的身份識別模型

// You can add profile data for the user by adding more properties to your ApplicationUser class, please visit http://go.microsoft.com/fwlink/?LinkID=317594 to learn more. 
    public class ApplicationUser : IdentityUser 
    { 
     public string userFname { get; set; } 
     public string userLname { get; set; } 
     public string address { get; set; } 
     public string userContactNo { get; set; } 
     public string commercialName { get; set; } 
     public string commercialAddress { get; set; } 
     public string commercialEmail { get; set; } 
     public string userType { get; set; } 

     public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager) 
     { 
      // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType 
      var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie); 
      // Add custom user claims here 
      return userIdentity; 
     } 
    } 

這裏是我的Registeration模型

public class RegisterViewModel 
{ 
    [Required] 
    [Display(Name = "User First Name")] 
    public string userFname { get; set; } 

    [Required] 
    [Display(Name = "User Last Name")] 
    public string userLname { get; set; } 

    [Required] 
    [Display(Name = "User Address")] 
    public string address { get; set; } 

    [Required] 
    [Display(Name = "User Contact Number")] 
    public string userContactNo { get; set; } 

    [Display(Name = "Commercial Name")] 
    public string commercialName { get; set; } 

    [Display(Name = "Commercial Address")] 
    public string commercialAddress { get; set; } 

    [EmailAddress] 
    [Display(Name = "Commercial Email")] 
    public string commercialEmail { get; set; } 

    [Key] 
    [Required] 
    [EmailAddress] 
    [Display(Name = "Email")] 
    public string Email { get; set; } 

    [Required] 
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} 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; } 

    [Required]   
    public string userType { get; set; } 

}

我如何做到這一點，

更新：正如他在我的答案波紋管評論，他想在同樣的方法來更新用戶的列表。所以這會起作用。

[HttpPost] 
public async Task<ActionResult> UpdateUserInfo(List<RegisterViewModel> model) 
{ 
    if (!ModelState.IsValid) 
    { 
     return View(model); 
    } 

    var userStore = new UserStore<ApplicationUser>(new 
            ApplicationDbContext()); 
    var appManager = new UserManager<ApplicationUser>(userStore); 

    // here you can do a foreach loop and get the email and assign new datas 
    foreach(var i in model) 
    { 
     var currentUser = appManager.FindByEmail(i.Email); 

     // here you can assign the updated values 
     currentUser.userFname = i.userFname; 
     // and rest fields are goes here 
     await appManager.UpdateAsync(currentUser); 
    } 
    var ctx = userStore.Context; 
    ctx.SaveChanges(); 
    // now you can redirect to some other method or-else you can return 
    // to this view itself by returning the data 

    return RedirectToAction("SomeActionMethod"); 
} 

是的，你應該在你的視場，並會有一個@Html.BeginForm和submit button來發表您的數據。或者 - 你可以通過ajax方法

希望它有幫助。

假設你ApplicationUser類是你的實體框架的DbContext的一部分，你可以檢索和更新用戶像這樣，使用實體框架;

var userId = "user id here"; // Set a user ID that you would like to retrieve 

var dbContext = new YourDbContext(); // Your entity framework DbContext 

// Retrieve a user from the database 
var user = dbContext.Set<ApplicationUser>().Find(userId); 

// Update a property on your user 
user.address = "New value"; 

// Save the new value to the database 
dbContext.SaveChanges(); 

如果您需要在當前的登錄用戶的用戶id，使用方法：

var userId = this.User.Identity.GetUserId(); 

多個用戶可以進行檢索和更新這樣的：

var dbContext = new YourDbContext(); 

// Get all users 
var users = dbContext.Set<ApplicationUser>().ToList(); 

foreach (var user in users) 
{ 
    user.address = "New value"; 
} 

// Save the new value to the database 
dbContext.SaveChanges(); 

實體框架會自動追蹤當你保存的時候每個變化。
