我对 MVC 很陌生。我是工作角色经理。在此之前,我将用户 ID 数据类型从字符串更改为 int。现在,我想在我的网站中担任角色。我已经创建了页面并添加了代码来运行该部分。运行网站后,当我点击创建新用户角色时,我在后台收到以下错误。这是我的代码:
private List<SelectListItem> GetAllRolesAsSelectList()
{
List<SelectListItem> SelectRoleListItems =
new List<SelectListItem>();
var roleManager =
new RoleManager<IdentityRole>(
new RoleStore<IdentityRole>(new ApplicationDbContext()));
var colRoleSelectList = roleManager.Roles.OrderBy(x => x.Name).ToList();
SelectRoleListItems.Add(
new SelectListItem
{
Text = "Select",
Value = "0"
});
foreach (var item in colRoleSelectList)
{
SelectRoleListItems.Add(
new SelectListItem
{
Text = item.Name.ToString(),
Value = item.Name.ToString()
});
}
return SelectRoleListItems;
}
这是引发错误的行
var roleManager =
new RoleManager<IdentityRole>(
new RoleStore<IdentityRole>(new ApplicationDbContext()));
这是我的 IdentityModel 页面代码:
public class CustomUserRole : IdentityUserRole<int>
{
}
public class CustomUserClaim : IdentityUserClaim<int>
{
}
public class CustomUserLogin : IdentityUserLogin<int>
{
}
public class CustomRole : IdentityRole<int, CustomUserRole>, IRole<int>
{
public CustomRole() : base() { }
public CustomRole(string name)
: this()
{
this.Name = name;
}
}
public class CustomUserStore : UserStore<ApplicationUser, CustomRole, int,
CustomUserLogin, CustomUserRole, CustomUserClaim>
{
public CustomUserStore(ApplicationDbContext context)
: base(context)
{
}
}
public class CustomRoleStore : RoleStore<CustomRole, int, CustomUserRole>
{
public CustomRoleStore(ApplicationDbContext context)
: base(context)
{
}
}
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, CustomRole,
int, CustomUserLogin, CustomUserRole, CustomUserClaim>
{
public ApplicationDbContext()
: base("SMSGoConnection")
{
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
}
帮助将不胜感激。
