this is wright code StreamWriter log; if (!File.Exists(Server.MapPath(log.txt))) { log = new StreamWriter(Server.MapPath(log.txt)); } else { log = File.AppendText(Server.MapPath(log.txt)); } // Write to the file: log.WriteLine(DateTime.Now); log.WriteLine(strResponse); // Close the stream: log.Close();

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( 
Log 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(); }
