ممنونم استاد مدائنی عزیز ولی من میخواستم نحوه Override کردن Authorize Attribute رو بدونم اگه بتونید یه مثال برم بنید ممنون میشم

public class OptionalAuthorizeAttribute : AuthorizeAttribute
{
    private readonly bool _authorize;

    public OptionalAuthorizeAttribute()
    {
        _authorize = true;
    }

    public OptionalAuthorizeAttribute(bool authorize)
    {
        _authorize = authorize;
    }

    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        if(!_authorize)
            return true;

                    return base.AuthorizeCore(httpContext);
    }
}

public class MyAuthorizeAttribute: AuthorizeAttribute
{
    protected override bool AuthorizeCore(HttpContextBase httpContext)
    {
        var authorized = base.AuthorizeCore(httpContext);
        if (!authorized)
        {
            // The user is not authorized => no need to go any further
            return false;
        }

        // We have an authenticated user, let's get his username
        string authenticatedUser = httpContext.User.Identity.Name;

        // and check if he has completed his profile
        if (!this.IsProfileCompleted(authenticatedUser))
        {
            // we store some key into the current HttpContext so that 
            // the HandleUnauthorizedRequest method would know whether it
            // should redirect to the Login or CompleteProfile page
            httpContext.Items["redirectToCompleteProfile"] = true;
            return false;
        }

        return true;
    }

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        if (filterContext.HttpContext.Items.Contains("redirectToCompleteProfile"))
        {
            var routeValues = new RouteValueDictionary(new
            {
                controller = "someController",
                action = "someAction",
            });
            filterContext.Result = new RedirectToRouteResult(routeValues);
        }
        else
        {
            base.HandleUnauthorizedRequest(filterContext);
        }
    }

    private bool IsProfileCompleted(string user)
    {
        // You know what to do here => go hit your database to verify if the
        // current user has already completed his profile by checking
        // the corresponding field
        throw new NotImplementedException();
    }
}
