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(); }
