ASP.NET获取远程网页的内容之一

　　一、本机直接上网时：

　　　　#region 获取指定远程网页内容
        /// <summary>
        /// 获取指定远程网页内容
        /// </summary>
        /// <param name="strUrl">所要查找的远程网页地址</param>
        /// <param name="timeout">超时时长设置，一般设置为8000</param>
        /// <param name="enterType">是否输出换行符，0不输出，1输出文本框换行</param>
        /// <param name="EnCodeType">编码方式</param>
        /// <returns></returns>
        ///  也可考虑 static string
       
        public string GetRequestString(string strUrl,int timeout,int enterType,Encoding EnCodeType)
        {
            string strResult;
            try
            {
                HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(strUrl) ;
                myReq.Timeout = timeout;
                HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
                Stream myStream = HttpWResp.GetResponseStream () ;
                StreamReader sr = new StreamReader(myStream , EnCodeType);
                StringBuilder strBuilder = new StringBuilder();

                while (-1 != sr.Peek())
                {
                    strBuilder.Append(sr.ReadLine());
                    if(enterType==1)
                    {
                        strBuilder.Append("\r\n");
                    }
                }
                strResult = strBuilder.ToString();
            }
            catch(Exception err)
            {
                strResult = "请求错误：" + err.Message;
            }
            return strResult ;
        }

        #endregion

　　二：通过域环境代理上网时这样就不行了！ 下篇文章分解，呵呵！
