Introduction:
Logging is the important part for Application Development.In this article i am going to explain with very simple steps.

Main:

Step 1: Create a Log Folder inside application directory,

string LogFolder = Path.Combine(AppDoamin.CurrentDomain.BaseDirectory,”Log”);
if(!Directory.Exists (LogFolder))
   Directory.CreateDirectory(LogFolder);

Step 2: Craete log File Inside LogFolder with datetime stamp.

String LogFile = Path.Combine(LogFolder,String.Format(“samplelog_{0}_{1}.log”,dt.Tostring(“yyyyMMdd”),dt.ToString(“hhmmss”)));

step 3:writing errors in log file,

TextWriter sampletwwriter=null;
sampletwwriter=new StreamWriter(logFile);

//function for writing all execptons in log file,

Private void logmes(string message)
{
sampletwwriter.WriteLine(String.Format(“[{0}] {1}”,DateTime.Now.ToString(),message));}

Conclusion:
Hope,this helps,
Happy Coding.
