Custom Authorization Attribute

like below fixes the issue I am implementing a CustomAuthorizeAttribute. I need to get the name of the action being executed. How can i get the name of current action name getting executed in the AuthorizeCore function which i am overriding ? , You can get the Action Name like this:
public class CustomAuthFilter : IAuthorizationFilter
    {
        public void OnAuthorization(AuthorizationContext filterContext)
        {
            filterContext.ActionDescriptor.ActionName;
        }
    }
public class CustomAuthAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        base.OnAuthorization(filterContext);
    }
}

Creating my custom security role and custom user group tables, to implement custom authorization for my asp.net mvc web

I hope this helps . If the ability exists to maintain the active domain groups there is no reason to maintain a local groups table isinrole can be used for group access checks

getting Roles that already set to custom Authorization attribute?

To fix the issue you can do by default it inhirits the Roles property from the base Authorize class so you can get the roles directly by using the Roles property
For Example
if (HttpContext.Current.User.Identity.IsAuthenticated && HttpContext.Current.User.IsInRole(Roles))
    {
        return true;
    }

Custom Authorization attribute asp.net core

To fix this issue Using policies for something like this isn't overkill. You need a requirement:
public class WhitelistRequirement: IAuthorizationRequirement
{
}
public class WhitelistHandler : AuthorizationHandler<WhitelistRequirement>
{

    // Implement a constructor to inject dependencies, such as your whitelist

    protected override Task HandleRequirementAsync(AuthorizationHandlerContext context,
                                                   WhitelistRequirement requirement)
    {
        if (isInWhitelist) // Your implementation here
        {
            context.Succeed(requirement);
        }

        return Task.CompletedTask;
    }
}
services.AddAuthorization(options =>
            options.AddPolicy("WhitelistPolicy",
            b => b.AddRequirements(new WhitelistRequirement())));

services.AddSingleton<IAuthorizationHandler, WhitelistHandler>();
[Authorize(Policy = "WhitelistPolicy")]
services.AddMvc(config =>
{
    var policy = new AuthorizationPolicyBuilder()
                     .AddRequirements(new WhitelistRequirement())
                     .Build();
    config.Filters.Add(new AuthorizeFilter(policy));
})
