一、定义类public class HttpWebResponseUtility{private static readonly string DefaultUserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";/// <summary>/// 创建GET方式的HTTP请求/// </summary>/// <param name="url">请求的URL</param>/// <param name="timeout">请求的超时时间</param>/// <param name="userAgent">请求的客户端浏览器信息，可以为空</param>/// <param name="cookies">随同HTTP请求发送的Cookie信息，如果不需要身份验证可以为空</param>/// <returns></returns>public static string CreateGetHttpResponse(string url,int? timeout,string userAgent=null,CookieCollection cookies=null){if(string.IsNullOrEmpty(url)){throw new ArgumentNullException("url");}HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;request.Method = "GET";request.UserAgent = DefaultUserAgent;if(!string.IsNullOrEmpty(userAgent)){request.UserAgent = userAgent;}if(timeout.HasValue){request.Timeout = timeout.Value;}if(cookies != null){request.CookieContainer = new CookieContainer();request.CookieContainer.Add(cookies);}HttpWebResponse webreponse = request.GetResponse() as HttpWebResponse;try{using(StreamReader reader = new StreamReader(webreponse.GetResponseStream(),System.Text.Encoding.UTF8)){return reader.ReadToEnd();}}catch(Exception exp){return exp.ToString();}}}
二、调用方式：
HttpWebResponseUtility.CreateGetHttpResponse(url,null);拿到字符串格式的HTML文本就可以写入新的html中。
，我要准备好行李启程了，谢谢关心我的家人和朋友，
