将文件从字符串或流上传到FTP服务器 [英] Upload a file to an FTP server from a string or stream

问题描述

我试图在FTP服务器上创建一个文件，但我所拥有的只是一个字符串或数据流以及它应该创建的文件名。有没有办法在服务器上创建文件（我没有创建本地文件的权限）？

  string location =ftp://xxx.xxx.xxx.xxx:21/TestLocation/Test.csv; 
 
 WebRequest ftpRequest = WebRequest.Create（location）; 
 ftpRequest.Method = WebRequestMethods.Ftp.UploadFile; 
 ftpRequest.Credentials = new NetworkCredential（userName，password）; 
 
 string data = csv.getData（）; 
 MemoryStream stream = csv.getStream（）; 
 
 // Magic 
 
 using（var response =（FtpWebResponse）ftpRequest.GetResponse（））{} 
  

解决方案

只需将您的流复制到FTP请求流即可：

p> Stream requestStream = ftpRequest.GetRequestStream（）;
stream.CopyTo（requestStream）;
requestStream.Close（）;


---

对于一个字符串（假设内容是文本）：

  byte [] bytes = Encoding.UTF8.GetBytes（data）; 
 
 Stream requestStream = request.GetRequestStream（）; 
 requestStream.Write（bytes，0，bytes.Length）; 
 requestStream.Close（）; 
  

如果内容是文本，则应使用文本模式：

  request.UseBinary = false; 
  

I'm trying to create a file on an FTP server, but all I have is either a string or a stream of the data and the filename it should be created with. Is there a way to create the file on the server (I don't have permission to create local files) from a stream or string?

string location = "ftp://xxx.xxx.xxx.xxx:21/TestLocation/Test.csv";

WebRequest ftpRequest = WebRequest.Create(location);
ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
ftpRequest.Credentials = new NetworkCredential(userName, password);

string data = csv.getData();
MemoryStream stream = csv.getStream();

//Magic

using (var response = (FtpWebResponse)ftpRequest.GetResponse()) { }

解决方案

Just copy your stream to the FTP request stream:

Stream requestStream = ftpRequest.GetRequestStream();
stream.CopyTo(requestStream);
requestStream.Close();

---

For a string (assuming the contents is a text):

byte[] bytes = Encoding.UTF8.GetBytes(data);

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

If the contents is a text, you should use a text mode:

request.UseBinary = false;
