本文实例讲述了C#使用post发送和接收数据的方法。分享给大家供大家参考。具体实现方法如下：

public partial class Post_Server : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { string type = ""; string Re = ""; Re += "数据传送方式："; if (Request.RequestType.ToUpper() == "POST") { type = "POST"; Re += type + "<br/>参数分别是：<br/>"; SortedList table = Param(); if (table != null) { foreach (DictionaryEntry De in table) { Re += "参数名：" + De.Key + " 值：" + De.Value + "<br/>"; } } else { Re = "你没有传递任何参数过来！"; } } else { type = "GET"; Re += type + "<br/>参数分别是：<br/>"; NameValueCollection nvc = GETInput(); if (nvc.Count != 0) { for (int i = 0; i < nvc.Count; i++){ Re += "参数名："+nvc.GetKey(i)+"值："+nvc.GetValues(i)[0]+"<br/>"; } } else { Re = "你没有传递任何参数过来！"; } } Response.Write(Re); } //获取GET返回来的数据 private NameValueCollection GETInput() { return Request.QueryString; } // 获取POST返回来的数据 private string PostInput() { try { System.IO.Stream s = Request.InputStream; int count = 0; byte[] buffer = new byte[1024]; StringBuilder builder = new StringBuilder(); while ((count = s.Read(buffer, 0, 1024)) > 0) { builder.Append(Encoding.UTF8.GetString(buffer,0,count)); } s.Flush(); s.Close(); s.Dispose(); return builder.ToString(); } catch (Exception ex) { throw ex; } } private SortedList Param() { string POSTStr = PostInput(); SortedList SortList = new SortedList(); int index = POSTStr.IndexOf("&"); string[] Arr = { }; if (index != -1) //参数传递不只一项 { Arr = POSTStr.Split('&'); for (int i = 0; i < Arr.Length; i++) { int equalindex = Arr[i].IndexOf('='); string paramN = Arr[i].Substring(0, equalindex); string paramV = Arr[i].Substring(equalindex + 1); if (!SortList.ContainsKey(paramN)) //避免用户传递相同参数 { SortList.Add(paramN, paramV); } else //如果有相同的，一直删除取最后一个值为准 { SortList.Remove(paramN); SortList.Add(paramN, paramV); } } } else //参数少于或等于1项 { int equalindex = POSTStr.IndexOf('='); if (equalindex != -1) { //参数是1项 string paramN = POSTStr.Substring(0, equalindex); string paramV = POSTStr.Substring(equalindex + 1); SortList.Add(paramN, paramV); } else //没有传递参数过来 { SortList = null; } } return SortList; }}protected void Button1_Click(object sender, EventArgs e){ Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); byte[] arrB = encode.GetBytes("aa=aa&bb=好飞"); HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://localhost:11626/MyTest/Post_Server.aspx"); myReq.Method = "POST"; myReq.ContentType = "application/x-www-form-urlencoded"; myReq.ContentLength = arrB.Length; Stream outStream = myReq.GetRequestStream(); outStream.Write(arrB, 0, arrB.Length); outStream.Close(); //接收HTTP做出的响应 WebResponse myResp = myReq.GetResponse(); Stream ReceiveStream = myResp.GetResponseStream(); StreamReader readStream = new StreamReader(ReceiveStream, encode); Char[] read = new Char[256]; int count = readStream.Read(read, 0, 256); string str = null; while (count > 0) { str += new String(read, 0, count); count = readStream.Read(read, 0, 256); } readStream.Close(); myResp.Close(); Response.Write(str);}

希望本文所述对大家的C#程序设计有所帮助。
