implementation of log file

Jun 2 2010 7:43 AM
Hi,
 I want to implement log file class in my wcf project then  i have to call 
its methods in an other class in this project .
 
Knowing that the call has done in the case of failure (if (ser.ConsulterFacture(NUM_FACTURE).Equals(-1))) . 
But i haven't any idea about how to implement the class of  log file.


If any one have an  idea , please help me :((((((((
