      See AlsoMembers Options: Show AllLanguage Filter: AllSend comments on this topic to ComponentPro
      Retrieves a direct access to the write-only data stream to send to.

      Syntax

      public Stream GetUploadStream(
         string remotePath
      )

      Parameters

      remotePath
      The filename of the file to write to. Some FTP servers may be case-sensitive.

      Return Value

      A Stream for writing data to the remote file.

      Remarks

      Because the FTP protocol does not support processing multiple commands or transfers at the same time, the stream has to be closed before any other FTP operation can be used.

      By default, the file will be uploaded to the current working directory. If you want to upload the file to another location, you could use the SetCurrentDirectory method to change the current working directory. Absolute paths can also be provided. However, some FTP servers might not support absolute paths, and different server types may have different ways of representing absolute paths. The current working directory can be retrieved via the GetCurrentDirectory method.

      Examples

      Shows how to use GetUploadStream method to decompress a file and upload to the server.

      using System;
      using System.IO;
      using ComponentPro.Compression;
      using ComponentPro.Net;
      
      ...
      
      // Create a new class instance.
      Ftp client = new Ftp();
      
      // Connect to the FTP server.
      client.Connect("192.168.0.211");
      
      // Authenticate.
      client.Authenticate("test", "test");
      
      // ... 
       
      // Get upload stream for remote file 'compressed.z'.
      Stream ostream = client.GetUploadStream("/compressed.z");
      // Create new file
      FileStream fi = new FileStream("d:\\temp\\uncompressed.dat", FileMode.Open, FileAccess.Read);
      // Create a new instance of the ZlibInputStream for the compression.
      ZlibStream zs = new ZlibStream(ostream, 9);
      byte[] buf = new byte[8192];
      int read;
      while ((read = fi.Read(buf, 0, 8192)) > 0) // Read from the Zlib stream.
      {
          zs.Write(buf, 0, read); // And write to the upload stream.
      }
      
      zs.Close();
      fi.Close();
      
      
      // ... 
       
      // Disconnect.
      client.Disconnect();
