Hi,
I am uploading a large text file to an SFTP server so I break it up and upload with an offset.
The first batch is uploaded correctly but on the subsequent upload I get an error. This is my code to upload:
long offSet = 0;
if (sftp.FileExists(sPath))
{
if (FirstUpload)
sftp.DeleteFile(sPath);
else
offSet = sftp.GetFileLength(sPath);
}
using (MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(sData)))
{
sftp.PutFile(stream, sPath, offSet, stream.Length);
}
And this is the log file:
