asp 采集不到数据，采集不成功 拒绝访问 msxml3.dll 错误 '80070005' 的解决方法

用 MSXML2.ServerXMLHTTP 一定行，其他几个好像不怎么行。

另外一篇文章 采集MSXML2.XMLHTTP“拒绝访问”的解决方案

        /// <summary>
        /// 获取远程文件源代码
        /// </summary>
        /// <param name="url">远程url</param>
        /// <returns></returns>
        public string GetHtmlCode(string Url)
        {
            string s = "";
            MSXML2.XMLHTTP _xmlhttp = new MSXML2.XMLHTTPClass();
            _xmlhttp.open("GET", Url, false, null, null);
            _xmlhttp.send("");
            if (_xmlhttp.readyState == 4)
            {
                s = System.Text.Encoding.Default.GetString((byte[])_xmlhttp.responseBody);
            }
            return s;
        }

　　上面这段代码不行，下面一段代码可以:

private string GetHtmlCode(string Url)
        {
            string strResult = "";

            try
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
                request.Method = "GET";
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                Stream streamReceive = response.GetResponseStream();
                Encoding encoding = Encoding.GetEncoding("GB2312");
                StreamReader streamReader = new StreamReader(streamReceive, encoding);
                strResult = streamReader.ReadToEnd();
            }
            catch { }

            return strResult;
        }
