ASP.NET 2.1身份改变PK为int错误 [英] ASP.NET Identity 2.1 change PK to int error

问题描述

我已经改变了PK中的 http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity ，但是经过我尝试登录，我得到的下面的错误。登录部分是成功的，因为这个包含了所有approperate数据，但创造的身份似乎失败

从物化'System.String'指定的强制转换类型的'System.Int32'类型无效。

在该行

  VAR的UserIdentity =等待manager.CreateIdentityAsync（这一点，DefaultAuthenticationTypes.ApplicationCookie）; 
  

该方法

 公共类ApplicationUser：IdentityUser< INT，CustomUserLogin，CustomUserRole，CustomUserClaim> 
 {
公共异步任务< ClaimsIdentity> GenerateUserIdentityAsync（的UserManager< ApplicationUser，INT>经理）
 {
 //注意authenticationType必须CookieAuthenticationOptions.AuthenticationType 
变种的UserIdentity =定义的匹配等待manager.CreateIdentityAsync（这一点，DefaultAuthenticationTypes.ApplicationCookie ）; 
 //添加自定义的用户要求在这里
返回的UserIdentity; 
} 
公共字符串名字{获得;组; } 
公共字符串名字{获得;组; } 
 
} 
  

解决方案

我有同样的问题以及..唯一的区别是，在我的错误是 AddToRole 或 AddToRoleAsync 。

从物化System.String类型指定的强制转换到'System.Int32'类型无效。

出错的行为：等待UserManager.AddToRoleAsync（user.Id，model.RoleId）;

事实证明，我需要更改表的键 AspNetRoles ，以及......也许这幅画使得它更清晰。

的

I have changed the PK as described in http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity, however after I try to login, i get the following error. The login part is successful because "this" contains all the approperate data, however creating identity seems to fail

The specified cast from a materialized 'System.String' type to the 'System.Int32' type is not valid.

at the line

var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

of the method

 public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> 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 string FirstName { get; set; }
    public string LastName { get; set; }

}

解决方案

I had the same problem as well.. the only difference is that my error is during AddToRole or AddToRoleAsync.

The specified cast from a materialized 'System.String' type to the 'System.Int32' type is not valid.

The offending line is at: await UserManager.AddToRoleAsync(user.Id, model.RoleId);

As it turns out, I need to change the key for table AspNetRoles as well... perhaps this picture makes it clearer..
