从字符串或流上传文件到FTP服务器

我正在尝试在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应该用它创建的文件名。 有没有办法在流或字符串上创建服务器上的文件（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()) { } 

Answer 1

只需将您的流复制到FTP请求流：

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

对于字符串（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; 

Answer 2

我这样做是为了将一个xml文件发送到FTP。 它工作正常。 我认为是你需要的。

  FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://XXXXXXXXXX//" + filename); request.Method = WebRequestMethods.Ftp.UploadFile; request.Credentials = new NetworkCredential("user", "pwd"); request.UsePassive = true; request.UseBinary = true; request.KeepAlive = true; StreamReader sourceStream = new StreamReader(file); byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd()); sourceStream.Close(); request.ContentLength = fileContents.Length; Stream requestStream = request.GetRequestStream(); requestStream.Write(fileContents, 0, fileContents.Length); requestStream.Close(); FtpWebResponse response = (FtpWebResponse)request.GetResponse(); 

问候！
