HttpRequest Get和Post调用其他页面的方法

 //Get请求方式
 private string RequestGet(string Url)
 {
 string PageStr = string.Empty;//用于存放还回的html
 Uri url = new Uri(Url);//Uri类 提供统一资源标识符 (URI) 的对象表示形式和对 URI 各部分的轻松访问。就是处理url地址
 try
 {
 HttpWebRequest httprequest = (HttpWebRequest)WebRequest.Create(url);//根据url地址创建HTTpWebRequest对象
 #region 参数设置
 httprequest.Method = "get";

 //---------------------------------------------设定一些参数（不必要可以）
 //httprequest.KeepAlive = false;//持久连接设置为false
 //httprequest.ProtocolVersion = HttpVersion.Version11;// 网络协议的版本
 //httprequest.Proxy = WebProxy.GetDefaultProxy();//服务器代理
 //httprequest.ContentType = "application/x-www-form-urlencoded";//http 头
 //httprequest.AllowAutoRedirect = true;
 //httprequest.MaximumAutomaticRedirections = 10;
 //httprequest.Timeout = 30000;//设定超时十秒（毫秒）
 //httprequest.UserAgent = "mozilla/4.0 (compatible; msie 6.0; windows nt 5.1)"; //浏览器
 //=================================================
 #endregion
 HttpWebResponse response = (HttpWebResponse)httprequest.GetResponse();//使用HttpWebResponse获取请求的还回值
 Stream steam = response.GetResponseStream();//从还回对象中获取数据流
 StreamReader reader = new StreamReader(steam, Encoding.GetEncoding("gb2312"));//读取数据Encoding.GetEncoding("gb2312")指编码是gb2312，不让中文会乱码的
 PageStr = reader.ReadToEnd();
 reader.Close();
 }
 catch (Exception e)
 {
 PageStr += e.Message;
 }
 return PageStr;
 }

//Post请求方式，于Get的方式写法相似，所以解释就些少一点了

 private string RequestPost(string Url,string Context)//两个参数分别是Url地址和Post过去的数据
 {
 string PageStr=string.Empty;
 Uri url = new Uri(Url);
 byte[] reqbytes=Encoding.ASCII.GetBytes(Context);
 try
 {
 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
 req.Method = "post";
 req.ContentType = "application/x-www-form-urlencoded";
 req.ContentLength = reqbytes.Length;
 Stream stm = req.GetRequestStream();
 stm.Write(reqbytes, 0, reqbytes.Length); stm.Close();
 HttpWebResponse wr = (HttpWebResponse)req.GetResponse();
 Stream stream = wr.GetResponseStream();
 StreamReader srd= new StreamReader(stream,Encoding.GetEncoding("gb2312"));
 PageStr += srd.ReadToEnd();
 stream.Close();
 srd.Close();
 }
 catch (Exception e)
 {
 PageStr += e.Message;
 }
 return PageStr; 
 }

public string WebClientGet(string url)
 {
 var client = new WebClient();
 client.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)");
 var stream = client.OpenRead(url);
 if (stream == null) return "";
 var reader = new StreamReader(stream, Encoding.Default);
 var result = reader.ReadToEnd();
 stream.Close();
 reader.Close();
 return result;
 }
