圖像不會上傳在網絡服務器上，但在本地確定

Question

我有一些圖像在服務器上我想上傳到另一臺服務器上我做代碼上傳服務器上的所有圖像，但可以在本地上傳，但我沒有知道什麼是錯的，它不能上傳到服務器上

 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); 
     }

有一個嘗試;

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();
