Question

我正在检查将默认用户添加到MVC 5应用程序。这段代码工作正常，但是如何通过种子方法在数据库中更新这些数据？例如，如果我想更改电子邮件地址？或者将用户添加到角色？任何帮助赞赏。

if (!context.Users.Any(u => u.UserName == "someone@someplace.com"))
{
    var store = new UserStore<ApplicationUser>(context);
    var manager = new UserManager<ApplicationUser>(store);
    var user = new ApplicationUser { UserName =
                                 "someone@someplace.com",
                              Email = "someone@someplace.com",
                              EmailConfirmed = true };
    manager.Create(user, "password");
}

您可以直接从DbContext进行修改。您不需要致电身份库。这是一个例子。

 using System.Data.Entity;
 using System.Linq;

 public class NameDbContextSeedData : 
 DropCreateDatabaseIfModelChanges<NameDbContext>
 {
    protected override void Seed(NameDbContext context)
    {
        var user = context.Users.Single(c => c.UserName ==
        "someone@someplace.com");

        user.UserName = "someone@someplace.com";
        user.Email = "someone@someplace.com";
        user.EmailConfirmed = true;

        context.SaveChanges();
    }
}
