try this, assuming your text file already exists
using System;

using System.IO;
class DirAppend {

public static void Main(String[] args)
{
StreamWriter w = File.AppendText("log.txt");
Log ("Test1", w);
Log ("Test2", w); // Close the writer and underlying
file. w.Close(); // Open and read the file.
StreamReader r = File.OpenText("log.txt");
DumpLog (r);
}
public static void Log (String logMessage, TextWriter w)
{
w.Write("\r\nLog Entry : ");
w.WriteLine("{0} {1}", DateTime.Now.ToLongTimeString(), DateTime.Now.ToLongDateString());
w.WriteLine(" :");
w.WriteLine(" :{0}", logMessage);
w.WriteLine ("-------------------------------"); // Update the underlying file. w.Flush(); }

public static void DumpLog (StreamReader r)
{ // While not at the end of the file, read and write lines.

String line;

while ((line=r.ReadLine())!=null)
{ Console.WriteLine(line);
}
r.Close();
} }

Hi Dharmesh,
Try this,
  public void writeFile()
  {
  FileStream fs = new FileStream(@"c:\Temp\Backup.txt", FileMode.OpenOrCreate, FileAccess.Write);
  StreamWriter m_streamWriter = new StreamWriter(fs);
  m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);
string strWrite=Datetime.Today.Date.Tostring();
  m_streamWriter.WriteLine(strWrite);
  m_streamWriter.Flush();
  m_streamWriter.Close();
  }
