发送字符串数据
发送数据

string strId = "guest";
        string strPassword = "";
 
        string postData = "userid=" + strId;
        postData += ("&password=" + strPassword);
 
        byte[] data = Encoding.UTF8.GetBytes(postData);
 
        // Prepare web request...
        HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://127.0.0.1:8058/PostResult.aspx");
 
        myRequest.Method = "POST";
        myRequest.ContentType = "application/x-www-form-urlencoded";
        myRequest.ContentLength = data.Length;
        Stream newStream = myRequest.GetRequestStream();
 
        // Send the data.
        newStream.Write(data, , data.Length);
        newStream.Close();
 
        // Get response
        HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
 
        StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
        string content = reader.ReadToEnd();
        Response.Write(content);

接收数据

Stream s = Request.InputStream;
        StreamReader sr = new StreamReader(s);
        string ss = sr.ReadToEnd();
        Response.Write(ss);

发送任意类型数据
发送数据

            //将图片转换成base64编码的流
 
            string a = Convert.ToBase64String(filecontent);
 
            //读取base64编码流，发送
 
            byte[] requestBytes = System.Text.Encoding.Default.GetBytes(a);
 
            req.Method = "POST";
 
            req.ContentType = "application/x-www-form-urlencoded";
 
            req.ContentLength = requestBytes.Length;
 
            Stream requestStream = req.GetRequestStream();
 
            requestStream.Write(requestBytes, , requestBytes.Length);
 
            requestStream.Close();
 
            //接收返回参数，到string backstr
 
            HttpWebResponse res = (HttpWebResponse)req.GetResponse();
 
            StreamReader sr = new StreamReader(res.GetResponseStream(), System.Text.Encoding.Default);
 
            string backstr = sr.ReadToEnd();
 
            sr.Close();
 
            res.Close();
 
            //输出参数
 
            Response.Write(backstr);

接收数据

//接收到的参数
            string bb = Request.QueryString["id"];
 
            Encoding myEncoding = Encoding.GetEncoding("utf-8");
 
            //接收传递过来的数据流
 
            Stream resStream = Request.InputStream;
 
            byte[] filecontent = new byte[resStream.Length];
 
            //将数据流读入byte数组
 
            resStream.Read(filecontent, , filecontent.Length);
 
            //数组转换为string以便转换base64使用
 
            string a = myEncoding.GetString(filecontent);
 
            //将string读取base64解密到byte数组
 
            byte[] filecontent2 = Convert.FromBase64String(a);
 
            //写入目录
 
            File.WriteAllBytes(Server.MapPath(bb + ".doc"), filecontent2);
 
            //返回值
 
            Response.Write("ok");
 
            Response.End();
