WINSCP SFTP CLIENT UPLOAD USING C# not working as a SERVICE

Hi Support,

I have created C# script to upload files to remote server. If i run exe is working fine.
My problem is, i am trying to create a service using two ways, It is not working in either way.
1) By using XYNTService, i am trying to call my C# application exe. for example my project name "winscpservice". i am trying to install winscpservice.exe using XYNTService.It is not uploading my file. Please suggest the problem.
2) Created own Service using Windows Service option, still not working.

here is my code:
class Program
{
const string logname = "log.xml";


static void Main(string[] args)
{
int fileExist = 0;
string fileName = null;
string fileName_rename = null;
while (true)
{
fileName = null;
//check file present : EZL_REDEEM or ATR_
//C:\Users\venkat\Desktop\
DirectoryInfo dir = new DirectoryInfo("C:\\Users\\venkat\\Desktop");//Directory.getCurrentDirectory());
foreach (FileInfo f in dir.GetFiles("exam*.txt"))
{
string curFile = f.ToString();
//string curFile

curFile = dir.ToString() + "\\" + curFile;
Console.WriteLine(File.Exists(curFile) ? fileExist = 1 : fileExist = 0);
// Console.WriteLine(File.Exists() ? "File exists." : "File does not exist.");

//string curFile = @"C:\Users\venkat\Desktop\*.txt";
//Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");
/// Run hidden WinSCP process
if (fileExist == 1)
{
Process winscp = new Process();
winscp.StartInfo.FileName = "winscp.com";
winscp.StartInfo.Arguments = "/log=" + logname;
winscp.StartInfo.UseShellExecute = false;
winscp.StartInfo.RedirectStandardInput = true;
winscp.StartInfo.RedirectStandardOutput = true;
winscp.StartInfo.CreateNoWindow = true;
winscp.Start();

/// Feed in the scripting commands
winscp.StandardInput.WriteLine("option batch abort");
winscp.StandardInput.WriteLine("option confirm off");
winscp.StandardInput.WriteLine("open sftp://venkat:1111@193.168.10.50:69 -privatekey=\"C:\\Documents and Settings\\Administrator\\Desktop\\key.ppk\"");
//winscp.StandardInput.WriteLine("ls");

fileName_rename = dir.ToString() + "\\" + "ren" + f.ToString();
// fileName_backup = dir.ToString() +"\\" + "temp"+"\\"+f.ToString();
File.Move(curFile, fileName_rename);
fileName = "put " + fileName_rename;// +" ren" + f.ToString();
winscp.StandardInput.WriteLine(fileName);
fileName = null;
fileName = "mv " + "ren" + f.ToString() + " " + f.ToString();
winscp.StandardInput.WriteLine(fileName);
winscp.StandardInput.Close();


/// Collect all output (not used in this example)
string output = winscp.StandardOutput.ReadToEnd();

/// Wait until WinSCP finishes
winscp.WaitForExit();

/// Parse and interpret the XML log
/// (Note that in case of fatal failure the log file may not exist at all)
XPathDocument log = new XPathDocument(logname);
XmlNamespaceManager ns = new XmlNamespaceManager(new NameTable());
ns.AddNamespace("w", "https://winscp.net/schema/session/1.0");
XPathNavigator nav = log.CreateNavigator();

/// Success (0) or error?
if (winscp.ExitCode != 0)
{
Console.WriteLine("Error occured");

/// See if there are any messages associated with the error
foreach (XPathNavigator message in nav.Select("//w:message", ns))
{
Console.WriteLine(message.Value);
}
}
else
{
/// It can be worth looking for directory listing even in case of
/// error as possibly only upload may fail
File.Delete(curFile);
XPathNodeIterator files = nav.Select("//w:file", ns);
Console.WriteLine(string.Format("There are {0} files and subdirectories:", files.Count));
foreach (XPathNavigator file in files)
{
Console.WriteLine(file.SelectSingleNode("w:filename/@value", ns).Value);
}
}
}
}
}
}
}

Please give me a suggestion, How to run scripts as service.
Thanks a lot.
