[Solved] Files getting Corrupted when uploading using FTP in ASP.Net

Need to remove the following part of code

using (StreamReader fileStream = new StreamReader(FileUpload1.PostedFile.InputStream))
{
    fileBytes = Encoding.UTF8.GetBytes(fileStream.ReadToEnd());
    fileStream.Close();
}

and replace

using (Stream requestStream = request.GetRequestStream())
{
     requestStream.Write(fileBytes, 0, fileBytes.Length);
     requestStream.Close();
}

with

using (var requestStream = request.GetRequestStream())
{
   CopyStream(FileUpload1.PostedFile.InputStream, requestStream);
   // no need to requestStream.Close(); - using does that for you
}

CopyStream Method

public static void CopyStream(Stream input, Stream output)
{
    byte[] buffer = new byte[32768];
    int read;
    while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
    {
        output.Write(buffer, 0, read);
    }
}

The uploaded file will not get corrupted
