HttpWebRequest 方式提交文件数据-以图片为例-白红宇

                    
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>");
