C#获得类的方法和方法参数

  Type t = typeof(CommonController);

            StringBuilder str = new StringBuilder();

            MethodInfo[] methors = t.GetMethods(BindingFlags.Instance | BindingFlags.Public);

            str.AppendFormat("路由:" + t.Name).AppendLine("");
            str.AppendFormat("描述" + md.Description).AppendLine("");

            foreach (var v in methors)
            {

                var af = v.GetCustomAttribute<Models.Attribute.APIFunctionAttribute>();
                if (af != null)
