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);
            var md = t.GetCustomAttribute<System.ComponentModel.DescriptionAttribute>();
            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)
                {
                    str.AppendFormat("	功能标识:{0}", v.Name).AppendLine("");
                    str.AppendFormat("	功能描述:{0}", af.Description).AppendLine("");
                    ParameterInfo[] ps = v.GetParameters();
                    str.AppendFormat("	参数:总数{0}", ps.Length).AppendLine("");
                    foreach (ParameterInfo p in ps)
