可以用HttpWebRequest和HttpWebResponse

或者WebRequest和WebResponse

//調(diào)用方法Dictionary<string, string> postData = new Dictionary<string, string>();postData.Add("user", "aaa");postData.Add("pass", "bbb"); GetPageByPost("http://www.xxx.com/send.aspx", postData, Encoding.UTF8); /// <summary>/// 以 Post 方式提交網(wǎng)頁數(shù)據(jù),獲得服務(wù)器返回的數(shù)據(jù)/// </summary>/// <param name="url"> Url </param>/// <param name="postData">Post 數(shù)據(jù)</param>/// <param name="encoder">網(wǎng)頁編碼</param>/// <returns>服務(wù)器返回的數(shù)據(jù)</returns>public string GetPageByPost(string url, Dictionary<string, string> postData, Encoding encoder){ string html = ""; HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(url); webReq.Method = "POST"; Stream reqStream = null; if (postData != null && postData.Count > 0) { StringBuilder sb = new StringBuilder(); foreach (KeyValuePair<string, string> kv in postData) { sb.Append(HttpUtility.UrlEncode(kv.Key)); sb.Append("="); sb.Append(HttpUtility.UrlEncode(kv.Value)); sb.Append("&"); } byte[] data = Encoding.UTF8.GetBytes(sb.ToString().TrimEnd('&')); webReq.ContentType = ContentType; webReq.ContentLength = data.Length; reqStream = webReq.GetRequestStream(); reqStream.Write(data, 0, data.Length); } HttpWebResponse webResp = (HttpWebResponse)webReq.GetResponse(); Stream stream = webResp.GetResponseStream(); StreamReader sr = new StreamReader(stream, encoder); html = sr.ReadToEnd(); sr.Close(); stream.Close(); if (reqStream != null) { reqStream.Close(); } return html;}
