13         string url = null;
14         //+  加号特殊处理
15         if (name.Contains("+"))

24         byte[] data = new byte[fs.Length];
25         fs.Read(data, 0, data.Length);
26         fs.Close();
27         HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
28         request.ContentType = "image/jpeg";
29         request.Method = "POST";
30         Encoding encoding = Encoding.UTF8;
31         request.ContentLength = data.Length;
32         Stream requestStream = request.GetRequestStream();
33         requestStream.Write(data, 0, data.Length);
34         requestStream.Close();
35 
36         HttpWebResponse response = (HttpWebResponse)request.GetResponse();
37         StreamReader streamReader = new StreamReader(response.GetResponseStream(), encoding);
38         string retString = streamReader.ReadToEnd();
39         streamReader.Close();
40         Console.WriteLine((count++) + "/" + files.Count);
41     }
42 }

服务器端代码：

 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Web.UI;
 6 using System.Web.UI.WebControls;
 7 using System.Net;
 8 using System.Text;
 9 using System.IO;
10 public partial class upload : System.Web.UI.Page

13     protected void Page_Load(object sender, EventArgs e)
14     {
15         string fPath = Server.MapPath("服务器端图片存储的虚拟目录名称");//得到虚拟目录的真实路径//检查存储目录
16         if (!Directory.Exists(fPath))
17         {
18             Directory.CreateDirectory(fPath);
19         }
20         string name = Request.QueryString["name"];//得到文件名
21         HttpUtility.UrlEncode(name, Encoding.GetEncoding("UTF-8"));
22         if (name != null)

46                     }
47                     stream.Close();
48                 }
