C# FTP 서버로 파일업로드질문이요!

        private string FtpAddress = "ftp://000.000.000.000/AAA";
        private string FtpId = "test";
        private string FtpPw = "1";
        private string FtpPath = "/";
        private string FileName = "PI21374_출하검사성적서.xls";
        private string localPath = @"C:/ex";
 
        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                FtpWebRequest requestFTPUploader = (FtpWebRequest)WebRequest.Create(FtpAddress + FtpPath + FileName);
 
                requestFTPUploader.Credentials = new NetworkCredential(FtpId, FtpPw);
                requestFTPUploader.Method = WebRequestMethods.Ftp.UploadFile;
 
                FileInfo fileInfo = new FileInfo(FileName);
                FileStream fileStream = fileInfo.OpenRead();
 
                int bufferLength = 2048;
                byte[] buffer = new Byte[bufferLength];
 
                Stream uploadStream = requestFTPUploader.GetRequestStream();
                int contentLength = fileStream.Read(buffer, 0, bufferLength);
 
                while (contentLength !=0)
                {
                    uploadStream.Write(buffer, 0, contentLength);
                    contentLength = fileStream.Read(buffer, 0, bufferLength);
                }
 
                uploadStream.Close();
                fileStream.Close();
                requestFTPUploader  = null;
            }
            catch (Exception eorror)
            {
                MessageBox.Show(eorror.Message);
            }
}
 
 
 
윈폼으로 버튼하나 누르면 ftp 서버로 파일업로드에 관해 코드수정중인데 
localPath 경로지정을 하긴했는데 소스에서 로컬경로를 어디다 넣어야할지, 수정해야할지 모르겠네요..ㅠㅠ
