在Db Initializer的种子方法中创建Asp.net身份用户 [英] Creating Asp.net Identity user in Seed method of Db Initializer

问题描述

我已经用EF 6代码创建了我的数据层，我通过种子方法填充数据库 EvInitializer class继承自 DropCreateDatabaseIfModelChanges 。 Seed 方法的实现是

  protected override void Seed（EvContext context ）
 {
 //使用上下文方法添加其他实体
 ApplicationUserManager manager = new ApplicationUserManager（new UserStore< ApplicationUser>（context））; 
 var user = new ApplicationUser {Email =[e-mail]，UserName =[e-mail]}; 
 var result = await manager.CreateAsync（user，Temp_123）; //此行给出错误。显然等待不能用于非异步方法，我不能使种子异步
} 
  

我的问题是如何使用 UserManager 类添加 Seed 方法中的用户。当我更改
var result = awit manager.CreateAsync（user，Temp_123）;

to

var result = manager.CreateAsync（user，Temp_123）。 //或.Wait

应用程序无限期挂起

解决方案

在asp .net-identity-2 usermanager具有非异步方法来创建。

  var user = new ApplicationUser {Email =admin @ myemail .com，UserName =[e-mail]}; 
 manager.Create（user，Temp_123）; 
  

如果您要创建admin角色，则与rolemanager相同。

  var roleManager = new RoleManager< IdentityRole>（new RoleStore< IdentityRole>（context））; 
 roleManager.Create（new Role（admin））; 
  

使用户管理

  manager.AddToRole（user.Id，admin）; 
  

编辑：随着trailmax评论， Create（）扩展方法来自 Microsoft.AspNet.Identity 命名空间，所以不要忘记使用Microsoft.AspNet.Identity

I have created my data layer with EF 6 code first and I am populating the db through Seed method of EvInitializer class inheriting from DropCreateDatabaseIfModelChanges. The implementation of Seed method is

protected override void Seed(EvContext context)
{
   //Add other entities using context methods
   ApplicationUserManager manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context));
   var user = new ApplicationUser { Email = "[e-mail]" ,UserName = "[e-mail]"};
   var result = await manager.CreateAsync(user, "Temp_123");//this line gives error. obviously await cannot be used in non- async method and I cannot make Seed async
}

My question is how I can add a user in Seed method using UserManager class. when I change var result = awit manager.CreateAsync(user, "Temp_123");
to
var result = manager.CreateAsync(user, "Temp_123").Result; //or .Wait
the application hangs indefinitely

解决方案

In asp.net-identity-2 usermanager has non async methods to create.

var user = new ApplicationUser { Email = "[e-mail]", UserName = "[e-mail]" };
manager.Create(user, "Temp_123");

Same for rolemanager if you want to create "admin" role.

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));
roleManager.Create(new Role("admin"));

make the user admin

manager.AddToRole(user.Id, "admin");

Edit: As trailmax commented, Create() extension method comes in with Microsoft.AspNet.Identity namespace so do not forget using Microsoft.AspNet.Identity
