本文介绍了更改用户ID类型在ASP.NET中的身份为int在VS2015的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

在默认情况下ASP.NET的身份在2015年VS使用一个字符串作为主键ASPNET ***表。我想用INT类型的的ID来代替。经过一番研究，事实证明，不同的类型化ID是由框架开箱即用的支持。在回答以下我将展示什么样的变化，使以实现这一目标。

更新：加入我的回答后，我发现在asp.net网站这个博客帖子描述相同，但多个COM prehensive：<一href=\"http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity\" rel=\"nofollow\">http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity

解决方案

IdentityModels.cs 改成这样：

  //新的派生类
公共类的UserRole：IdentityUserRole＆LT; INT＆GT;
{
}公共类UserClaim：IdentityUserClaim＆LT;＆诠释GT;
{
}公共类用户登陆：IdentityUserLogin＆LT;＆诠释GT;
{
}公共类角色：IdentityRole＆LT; INT，UserRole的＆GT;
{
    公共角色（）{}
    公共角色（字符串名称）{名称=名称; }
}公共类UserStore：UserStore＆LT; ApplicationUser，角色，INT，
    用户登陆，UserRole的，UserClaim＆GT;
{
    公共UserStore（ApplicationDbContext上下文）：基地（上下文）
    {
    }
}公共类Rolestore的：Rolestore的＆LT;作用，INT的UserRole＆GT;
{
    公共Rolestore的（ApplicationDbContext上下文）：基地（上下文）
    {
    }
}//你可以通过添加更多的属性你ApplicationUser类用户添加配置文件数据，请访问http://go.microsoft.com/fwlink/?LinkID=317594，以了解更多信息。
公共类ApplicationUser：IdentityUser＆LT; INT，用户登陆，UserRole的，UserClaim＆GT;
{
    公众的DateTime？ ActiveUntil;    公共异步任务＆LT; ClaimsIdentity＆GT; GenerateUserIdentityAsync（ApplicationUserManager经理）
    {
        //注意authenticationType必须CookieAuthenticationOptions.AuthenticationType定义的匹配
        VAR的UserIdentity =等待manager.CreateIdentityAsync（这一点，DefaultAuthenticationTypes.ApplicationCookie）;
        //添加自定义的用户在这里声明
        返回的UserIdentity;
    }
}公共类ApplicationDbContext：IdentityDbContext＆LT; ApplicationUser，角色，INT，
    用户登陆，UserRole的，UserClaim＆GT;
{
    公共ApplicationDbContext（）
        ：基地（DefaultConnection）
    {
    }    公共静态ApplicationDbContext的Create（）
    {
        返回新ApplicationDbContext（）;
    }
}

在`App_Start \\ IdentityConfig.cs，更改以下类：

 公共类ApplicationUserManager：＆的UserManager LT; ApplicationUser，INT＆GT;
{
    公共ApplicationUserManager（IUserStore＆LT; ApplicationUser，INT＆GT;存储）
        ：基地（存储）
    {
    }    公共静态ApplicationUserManager创建（IdentityFactoryOptions＆LT; ApplicationUserManager＆gt;选项，IOwinContext上下文）
    {
        VAR经理=新ApplicationUserManager（新UserStore（context.Get＆LT; ApplicationDbContext＆GT;（）））;
        //配置用户名验证逻辑
        manager.UserValidator =新UserValidator＆LT; ApplicationUser，INT＆GT;（经理）
        {
            AllowOnlyAlphanumericUserNames =假，
            RequireUniqueEmail =真
        };        //配置密码验证逻辑
        manager.PasswordValidator =新PasswordValidator
        {
            RequiredLength = 8，
            // RequireNonLetterOrDigit = TRUE，
            RequireDigit = TRUE，
            RequireLowercase = TRUE，
            RequireUppercase = TRUE，
        };        //配置用户锁定默认
        manager.UserLockoutEnabledByDefault = TRUE;
        manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes（5）;
        manager.MaxFailedAccessAttemptsBeforeLockout = 5;        //注册双因素身份验证提供者。此应用程序使用手机和电子邮件作为接收code用于验证用户的步骤
        //你可以写自己的供应商，并在这里插入。
        manager.RegisterTwoFactorProvider（手机code，新PhoneNumberTokenProvider＆LT; ApplicationUser，INT＆GT;
        {
            MessageFormat =您的安全code是{0}
        }）;
        manager.RegisterTwoFactorProvider（电子邮件code，新EmailTokenProvider＆LT; ApplicationUser，INT＆GT;
        {
            主题=安全code，
            BodyFormat =您的安全code是{0}
        }）;
        manager.EmailService =新EmailService（）;
        manager.SmsService =新SmsService（）;
        VAR dataProtectionProvider = options.DataProtectionProvider;
        如果（dataProtectionProvider！= NULL）
        {
            manager.UserTokenProvider =
                新DataProtectorTokenProvider＆LT; ApplicationUser，INT＆GT;（dataProtectionProvider.Create（ASP.NET身份））;
        }
        返回经理;
    }
}//配置应用程序登录管理器，它是本应用中使用。
公共类ApplicationSignInManager：SignInManager＆LT; ApplicationUser，INT＆GT;
{
    公共ApplicationSignInManager（ApplicationUserManager的UserManager，IAuthenticationManager AuthenticationManager会）
        ：基地（的UserManager，AuthenticationManager会）
    {
    }    公共覆盖任务＆LT; ClaimsIdentity＆GT; CreateUserIdentityAsync（ApplicationUser用户）
    {
        返回user.GenerateUserIdentityAsync（（ApplicationUserManager）的UserManager）;
    }    公共静态ApplicationSignInManager创建（IdentityFactoryOptions＆LT; ApplicationSignInManager＆gt;选项，IOwinContext上下文）
    {
        返回新ApplicationSignInManager（context.GetUserManager＆LT; ApplicationUserManager＆GT;（），context.Authentication）;
    }
}

在 App_Start \\ Startup.Auth.cs 变更 OnValidateIdentity 属性如下：

  OnValidateIdentity = SecurityStampValidator.OnValidateIdentity＆LT; ApplicationUserManager，ApplicationUser，INT＆GT;（
    validateInterval：TimeSpan.FromMinutes（30），
    regenerateIdentityCallback：（经理，用户）=＆GT; user.GenerateUserIdentityAsync（经理）
    getUserIdCallback：ID =＆GT; id.GetUserId＆LT; INT＆GT;（））

更改ManageController与新的PK类型的工作：

替换 User.Identity.GetUserId的所有条目（）到 User.Identity.GetUserId＆LT; INT＆GT;（）

有可能是一对夫妇的字符串需要更改为 INT ID 参数，但仅此而已

By default ASP.NET Identity in VS 2015 uses a string as a primary key for AspNet*** tables. I wanted to to use int-typed id's instead. After some research it turned out that different typed id's are supported by the framework out of the box. In the answer below I will show what changes to make to achieve that.

UPDATE: After adding my answer I found this blog post on asp.net site that describes the same but more comprehensive: http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity

解决方案

IdentityModels.cs change to this:

// New derived classes
public class UserRole : IdentityUserRole<int>
{
}

public class UserClaim : IdentityUserClaim<int>
{
}

public class UserLogin : IdentityUserLogin<int>
{
}

public class Role : IdentityRole<int, UserRole>
{
    public Role() { }
    public Role(string name) { Name = name; }
}

public class UserStore : UserStore<ApplicationUser, Role, int,
    UserLogin, UserRole, UserClaim>
{
    public UserStore(ApplicationDbContext context): base(context)
    {
    }
}

public class RoleStore : RoleStore<Role, int, UserRole>
{
    public RoleStore(ApplicationDbContext context): base(context)
    {
    }
}

// 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<int, UserLogin, UserRole, UserClaim>
{
    public DateTime? ActiveUntil;

    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager 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 ApplicationDbContext : IdentityDbContext<ApplicationUser, Role, int,
    UserLogin, UserRole, UserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

In `App_Start\IdentityConfig.cs, change the following classes:

public class ApplicationUserManager : UserManager<ApplicationUser, int>
{
    public ApplicationUserManager(IUserStore<ApplicationUser, int> store)
        : base(store)
    {
    }

    public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context) 
    {
        var manager = new ApplicationUserManager(new UserStore(context.Get<ApplicationDbContext>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser, int>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };

        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 8,
            // RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };

        // Configure user lockout defaults
        manager.UserLockoutEnabledByDefault = true;
        manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
        manager.MaxFailedAccessAttemptsBeforeLockout = 5;

        // Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
        // You can write your own provider and plug it in here.
        manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser, int>
        {
            MessageFormat = "Your security code is {0}"
        });
        manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser, int>
        {
            Subject = "Security Code",
            BodyFormat = "Your security code is {0}"
        });
        manager.EmailService = new EmailService();
        manager.SmsService = new SmsService();
        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            manager.UserTokenProvider = 
                new DataProtectorTokenProvider<ApplicationUser, int>(dataProtectionProvider.Create("ASP.NET Identity"));
        }
        return manager;
    }
}

// Configure the application sign-in manager which is used in this application.
public class ApplicationSignInManager : SignInManager<ApplicationUser, int>
{
    public ApplicationSignInManager(ApplicationUserManager userManager, IAuthenticationManager authenticationManager)
        : base(userManager, authenticationManager)
    {
    }

    public override Task<ClaimsIdentity> CreateUserIdentityAsync(ApplicationUser user)
    {
        return user.GenerateUserIdentityAsync((ApplicationUserManager)UserManager);
    }

    public static ApplicationSignInManager Create(IdentityFactoryOptions<ApplicationSignInManager> options, IOwinContext context)
    {
        return new ApplicationSignInManager(context.GetUserManager<ApplicationUserManager>(), context.Authentication);
    }
}

In App_Start\Startup.Auth.cs change OnValidateIdentity property to this:

OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser, int>(
    validateInterval: TimeSpan.FromMinutes(30),
    regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager),
    getUserIdCallback: id => id.GetUserId<int>())

Change ManageController to work with the new pk type:

Replace all entries of User.Identity.GetUserId() to User.Identity.GetUserId<int>()

There might be a couple of string id arguments that need to be changed to int, but that's about it.
