Question

我有一些图像在服务器上我想上传到另一台服务器上我做代码上传服务器上的所有图像，但可以在本地上传，但我没有知道什么是错的，它不能上传到服务器上

 try 
     { 
      byte[] content; 
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); 
      WebResponse response = request.GetResponse(); 

      Stream stream = response.GetResponseStream(); 

      using (BinaryReader br = new BinaryReader(stream)) 
      { 
       content = br.ReadBytes(500000); 
       br.Close(); 
      } 
      response.Close(); 

      string CompleteDPath = "ftp path"; 
      string UName = "abc"; 
      string PWD = "123"; 



      WebRequest reqObj = WebRequest.Create(CompleteDPath + file_name); 
      reqObj.Method = WebRequestMethods.Ftp.UploadFile; 
      reqObj.Credentials = new NetworkCredential(UName, PWD); 
      reqObj.GetRequestStream().Write(content, 0, content.Length); 
      reqObj = null; 



      //FileStream fs = new FileStream(file_name, FileMode.Create); 
      //BinaryWriter bw = new BinaryWriter(fs); 

      //bw.Write(content); 
      //fs.Close(); 
      //bw.Close(); 
     } 
     catch (Exception ex) 
     { 
      Response.Write(ex.Message); 
     }

有一个尝试;

byte[] content;  

HttpWebRequest request1 = (HttpWebRequest)WebRequest.Create(url);  

WebResponse response1 = request1.GetResponse(); 

Stream stream = response1.GetResponseStream(); 

using (BinaryReader br = new BinaryReader(stream)) 
{ 
    content = br.ReadBytes((int)stream.Length); 
    br.Close(); 
} 
response1.Close(); 


FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://ftp_path"); 
request.Method = WebRequestMethods.Ftp.UploadFile; 

request.Credentials = new NetworkCredential("abc", "123"); 
request.ContentLength = content.Length; 

Stream requestStream = request.GetRequestStream(); 
requestStream.Write(content, 0, content.Length); 
requestStream.Close(); 

FtpWebResponse response = (FtpWebResponse)request.GetResponse(); 
response.Close();
