HttpWebRequest 方式提交文件数据-以图片为例

public void StartPing1(string pingURL)

        {

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(pingURL);

            FileStream fs = new FileStream(@"D:\111.jpg", FileMode.Open, FileAccess.Read);

            Byte[] bytes = new Byte[10240];

            request.Method = "POST";

            request.Proxy = null;

            //request.Headers.Add("XXX", "XXX");

            request.ContentType = "application/octet-stream";

            Stream dataStream = request.GetRequestStream();

            int count = fs.Read(bytes, 0, 10240);

            while (count != 0)

            {

                dataStream.Write(bytes, 0, count);

                count = fs.Read(bytes, 0, 10240);

            }

            fs.Close();

            dataStream.Close();

            try

            {

                HttpWebResponse response = (HttpWebResponse)request.GetResponse();

                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.ASCII);

                string ret = sr.ReadToEnd();

                response.Close();

            }

            catch (System.Exception ex)

            {

                Console.WriteLine("!!!!!!ERROR!!!!!!!!" + ex.ToString() + "!!!!!!!!ERROR!!!!!!!!");

            }

        }

　　

---下面是服务器端接收方法：

加载事件中：

/* 

            //StartPing1 方法 传送文件的

            System.Drawing.Image postImage = System.Drawing.Image.FromStream(Request.InputStream);

            System.Drawing.Bitmap bitmap_b = new System.Drawing.Bitmap(postImage);

            string Opath = @"D:\";

            string photoname = DateTime.Now.Ticks.ToString();

            bitmap_b.Save(Opath + "\\" + photoname + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

            Response.Write("<?xml version=\"1.0\"?><params><title>OK</title></params>");
