实体类型IdentityUser不是ASP.NET Identity中当前上下文的模型的一部分 [英] The entity type IdentityUser is not part of the model for the current context in ASP.NET Identity

问题描述

我想检查ASP.NET Identity中是否存在具有特定用户名和密码的用户.我试过了，这就是我的代码:

I want to check if there is a user with particular username and password in ASP.NET Identity. I tried and that is my code:

UserManager<IdentityUser> userManager = new UserManager<IdentityUser>(new UserStore<IdentityUser>(new ApplicationDbContext()));
var user = await userManager.FindAsync(userName, password);

但是，出了点问题，那就是错误:

However, something goes wrong and that is the error:

实体类型IdentityUser不是当前模型的一部分 上下文.

The entity type IdentityUser is not part of the model for the current context.

您能告诉我解决方案吗?

Would you tell me a solution?

推荐答案

如果使用默认的MVC项目，则必须使用ApplicationUser模型而不是IdentityUser并按如下所示更新代码:

If you are using default MVC project you have to use ApplicationUser model instead of IdentityUser and update your code as follow:

  public async Task<ViewResult> Index()
    {
        UserManager<ApplicationUser> userManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(new ApplicationDbContext()));
        var user = await userManager.FindAsync("UserName", "Password");
        return View(user);
    }
