在属性中使用输入参数（Asp Core 3.1）

Question

我有这个属性：

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class AllowAccessAttribute : Attribute, IAuthorizationFilter
{
    private readonly IDomainUnitOfWork unitofwork;
    private readonly IHttpContextAccessor httpContext;
    private readonly string _name;

    public AllowAccessAttribute(string name)
    {
        _name = name;

    }
    public string Name => _name;
    public AllowAccessAttribute(IDomainUnitOfWork unitofwork, IHttpContextAccessor httpContext)
    {
        this.unitofwork = unitofwork;
        this.httpContext = httpContext;
    }
    public void OnAuthorization(AuthorizationFilterContext context)
    {
        string controller = context.RouteData.Values["controller"].ToString();
        string action = context.RouteData.Values["action"].ToString();
        var userId = httpContext.HttpContext.User.Identity.GetUserId<long>();
        var access = string.Format("{0}:{1}", controller, action);
        if (unitofwork.UserRepository.AccessLevelRepository.ValidateAccess(userId, access) == false)
            context.Result = new StatusCodeResult(403);
    }
}

我通过这种方式在我的行动之上调用这个属性：

[TypeFilter(typeof(AllowAccessAttribute))]

但我有问题。 我需要将参数Name传递给这个属性。

我怎么能传递参数？？？

您可以像这样使用您的属性：

[AllowAccess("name")]
