有人用 goto 语句么？我是用它代替递归

//递归
void repeat(c) {

	
		//需要重复的代码
	

		if (xx) {
			 repeat(xx);
		}

}

//goto 代替递归
void repeat(c) {

	loop:
		//需要重复的代码
	

		if (xx) {
			goto loop;
		}

}

        //一个采集程序
        public void Run(string listurl)
        {
            using (var wc = new WebClient())
            {
                loop:

                string html = Encoding.GetEncoding("utf-8").GetString(wc.DownloadData(listurl));
                var doc = new HtmlDocument();
                doc.LoadHtml(html);
                var nodes = doc.DocumentNode.SelectNodes("//ul[@id=\"data_list\"]/li/div/a");
                for (int i = 0; i < nodes.Count; i++)
                {
                    var node = nodes[i];
                    string link = "http://www..cn" + node.Attributes["href"].Value;
                    string title = node.SelectSingleNode("span[@class=\"sTit\"]").InnerText;
                    Save(title, link);
                }
                var nextnode = doc.DocumentNode.SelectSingleNode("//div[@class='page mb clearfixs']/em/following-sibling::a");
                if (nextnode != null)
                {
                    listurl = "http://www..cn" + nextnode.Attributes["href"].Value;
                    goto loop;
                }
            }
        }
