学习C#有几天了，与DELPHI对比，C#能更快、更有效的解决一些问题。

语法都大同小异，贴出一段百度关键词查询的多线程代码，以备后用。

        //查询百度关键词排名多线程
        private void createBDKEYThreadThread()
        {

            WebHtml = "";
            PageNo = 1;         
            string key = (textBox8.Text);
            WebHtml = getHttp("http://www.baidu.com/s?wd=" + key,null); //获取源码

            for (int j = 0; j < 100; j++)
            {

                Regex r = new Regex(textBox3.Text);
                Match m = r.Match(WebHtml); // 在字符串中匹配网址           //等同于DELPHI的POS（）函数

                if (m.Success) 
                {
                    //==============================================================================================
                    //找到排名-------->推广站
                    //==============================================================================================
                    string[] resultString1 = Regex.Split(WebHtml, "f EC_PP", RegexOptions.IgnoreCase); //这一块比DELPHI的分割函数更有效率的获取
                    for (int i = 1; i < resultString1.Length; i++)

                        }
                    }

                }
                else
                {

                    PageNo = PageNo + 1;
                    label7.Text = "正在查询第" + PageNo.ToString() + "页";
