本文實例講述了C#應用post發送和吸收數據的辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

public partial class Post_Server : System.Web.UI.Page
{
 protected void Page_Load(object sender, EventArgs e)
 {
  string type = "";
  string Re = "";
  Re += "數據傳送方法：";
  if (Request.RequestType.ToUpper() == "POST")
  {
   type = "POST";
   Re += type + "<br/>參數分離是：<br/>";
   SortedList table = Param();
   if (table != null)
   {
    foreach (DictionaryEntry De in table) {
     Re += "參數名：" + De.Key + " 值：" + De.Value + "<br/>";
    }
   }
   else
   { Re = "你沒有傳遞任何參數過去！"; }
  }
  else
  {
   type = "GET";
   Re += type + "<br/>參數分離是：<br/>";
   NameValueCollection nvc = GETInput();
   if (nvc.Count != 0)
   {
    for (int i = 0; i < nvc.Count; i++){
    Re += "參數名："+nvc.GetKey(i)+"值："+nvc.GetValues(i)[0]+"<br/>";
 }
   }
   else
   { Re = "你沒有傳遞任何參數過去！"; }
  }
  Response.Write(Re);
 }
 //獲得GET前往來的數據
 private NameValueCollection GETInput()
 { return Request.QueryString; }
 // 獲得POST前往來的數據
 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) //參數傳遞不只一項
  {
   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))
    //防止用戶傳遞雷同參數
    { SortList.Add(paramN, paramV); }
    else //假如有雷同的，一向刪除取最初一個值為准
    {
     SortList.Remove(paramN); SortList.Add(paramN, paramV);
    }
   }
  }
  else //參數少於或等於1項
  {
   int equalindex = POSTStr.IndexOf('=');
   if (equalindex != -1)
   { //參數是1項
    string paramN = POSTStr.Substring(0, equalindex);
    string paramV = POSTStr.Substring(equalindex + 1);
    SortList.Add(paramN, paramV);
   }
   else //沒有傳遞參數過去
   { 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=好飛");
  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();
  //吸收HTTP做出的呼應
  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);
}
