Append text using StreamWriter

Question

This is probably a pretty simple question   In C  I m trying to write a simple method  called my  DebugWrite  method  to write out any exceptions caught within my program to a text file stored locally  My current code only writes a new file every time  using StreamWriter  How do you program it to check if the file already exists  and if so to append to the current text    IE   If  Exist debug txt      Write new debug txt    else if exist debug txt       Append new text

Also look at log4net  which makes logging to 1 or more event stores  mdash  whether it s the console  the Windows event log  a text file  a network pipe  a SQL database  etc   mdash  pretty trivial  You can even filter stuff in its configuration  for instance  so that only log records of a particular severity  say ERROR or FATAL  from a single component or assembly are directed to a particular event store   http   logging apache org log4net
