ASP.NET标识成员身份登录失败错误

Question

我已使用默认字符串作为用户ID实现了ASP.NET Identity。

当我尝试使用无效的用户名登录时，它会起作用并显示消息＆＃34;无效的登录尝试＆＃34;。 当我尝试使用正确的用户名和密码登录时，它让我进入并正常工作。

问题是当我尝试使用正确的用户名和错误的密码时，我得到了类型转换异常。某种程度上有些东西试图将用户ID转换为int。

尝试了一切，但似乎没有效果。 这是我的身份配置代码：

public class ApplicationUserManager : UserManager<ApplicationUser>
{
    public ApplicationUserManager(IUserStore<ApplicationUser> store) : base(store)
    {
        this.UserValidator = new UserValidator<ApplicationUser>(this)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true
        };
        this.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = false,
            RequireDigit = false,
            RequireLowercase = false,
            RequireUppercase = false,
        };

        this.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
