【问题描述】：

使用http://www.asp.net/identity 中的示例我已经做到了这一点。 RoleManager 工作完美，我对待 UserManager 也是一样的。我认为一切都是正确的，但我似乎无法在控制器中正确地新建 UserManager。怎么了？有一次，我成功地让UserManager 工作，但是在使用UserManager.Create(user, password); 创建一个新用户时得到一个EntityValidationError 说“需要ID”，正如在这个问题UserManager.Create(user, password) thowing EntityValidationError saying Id is required? 中发布的那样。

因此，经过一段时间的碰碰运气，我创建了如下所示的所有内容，但在 new ApplicationUserManager(new ApplicationUserStore(new MyAppDb())) 上出现编译时错误说：

MyApp.Models.ApplicationUserManager.ApplicationUserManager(Microsoft.AspNet.Identity.IUserStore)'的最佳重载方法匹配 有一些无效的参数”

尝试在我的控制器中创建 UserManager 时：

这里是控制器：

namespace MyApp.Controllers

    [Authorize]
    public class AccountController : BaseController
    
        public AccountController()
            : this(new ApplicationUserManager(new ApplicationUserStore(new MyAppDb())))
        
        

        public AccountController(ApplicationUserManager userManager)
        
            UserManager = userManager;
        

        public ApplicationUserManager UserManager  get; private set; 
...

这是模型：

namespace MyApp.Models

    public class ApplicationUser : IdentityUser<string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    
        [Required]
        [StringLength(50)]
        public string FirstName  get; set; 

        [Required]
        [StringLength(50)]
        public string LastName  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;
        
    

    public class ApplicationUserLogin : IdentityUserLogin<string>
    
    

    public class ApplicationUserClaim : IdentityUserClaim<string>
    
    

    public class ApplicationUserRole : IdentityUserRole<string>
    
    

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
    
        [Required]
        [StringLength(50)]
        public string ProperName  get; set; 

        [Required]
        public string Description  get; set; 
    


    public class MyAppDb : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    
        public MyAppDb()
            : base("MyAppDb")
        
        
    


    public class ApplicationUserManager : UserManager<ApplicationUser>
    
        public ApplicationUserManager(IUserStore<ApplicationUser> store)
            : base(store)
        
            this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
            this.UserValidator = new UserValidator<ApplicationUser>(this)  AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true ;
        

    

    public class ApplicationUserStore : UserStore<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
    
        public ApplicationUserStore(MyAppDb context)
            : base(context)
        
        

        public override async Task CreateAsync(ApplicationUser user)
        
            await base.CreateAsync(user);

        
    

    
    public class ApplicationRoleStore : RoleStore<ApplicationRole, string, ApplicationUserRole>
    
        public ApplicationRoleStore(MyAppDb context)
            : base(context)
        
        
    

    public class ApplicationRoleManager : RoleManager<ApplicationRole>
    
        public ApplicationRoleManager(IRoleStore<ApplicationRole, string> store)
            : base(store)
        
        

    

更新：我可以通过更改以下内容来消除创建 UserManager 时出现的错误：

public class ApplicationUserManager : UserManager<ApplicationUser>

    public ApplicationUserManager(IUserStore<ApplicationUser> store)
        : base(store)
    
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this)  AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true ;
    

到这里：

public class ApplicationUserManager : UserManager<ApplicationUser>

    public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        : base(store)
    
        this.PasswordValidator = (IIdentityValidator<string>)new MinimumLengthValidator(8);
        this.UserValidator = new UserValidator<ApplicationUser>(this)  AllowOnlyAlphanumericUserNames = false, RequireUniqueEmail = true ;
    

注意我刚刚添加了, string，但随后出现错误“Microsoft.AspNet.Identity.UserMaager.UserManager(Microsoft.AspNet.Identity.IUserStore)' 在base(store) 上有一些无效参数。

更新 2：我改变了这个：

public class ApplicationUserManager : UserManager<ApplicationUser>
    
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    

到这里：

public class ApplicationUserManager : UserManager<ApplicationUser, string>
    
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
        ...
    

注意public class ApplicationUserManager : UserManager<ApplicationUser, string> 中的' string。但现在，你猜怎么着？你猜对了——回到这个问题：UserManager.Create(user, password) thowing EntityValidationError saying Id is required?

我错过了什么？

【问题讨论】：

UserManager.Create(user, password) thowing EntityValidationError saying Id is required?的可能重复

【参考方案1】：

试试这个方法。我有同样的问题，你需要提供身份证。

    //
    // POST: /Account/Register
    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegisterViewModel model)
    
        if (ModelState.IsValid)
        
            var user = new ApplicationUser()  
                UserName = model.UserName,
                Id = Guid.NewGuid().ToString(),
                Created = DateTime.Now,
                LastLogin = null
            ;

            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            
                await SignInAsync(user, isPersistent: false);
                return RedirectToAction("Index", "Home");
            
            else
            
                AddErrors(result);
            



        

        // If we got this far, something failed, redisplay form
        return View(model);
