I’m bookmarking this site: http://www.c-sharpcorner.com/UploadFile/scottlysle/EventAndErrorLogging1… It’s an easy cut and paste code for writing to the event viewer.

using System.Diagnostics;

public class EventLogger

{

public New()

{

//default constructor

}

…

Like the ErrorLogger.cs class, this class contains only a single function used to write directly to the event log: (modified to fit on this page)

//*************************************************************

//NAME: WriteToEventLog

//PURPOSE: Write to Event Log

//PARAMETERS: Entry – Value to Write

// AppName – Name of Client Application. Needed

// because before writing to event log, you must

// have a named EventLog source.

// EventType – Entry Type, from EventLogEntryType

// Structure e.g., EventLogEntryType.Warning,

// EventLogEntryType.Error

// LogNam1e: Name of Log (System, Application;

// Security is read-only) If you

// specify a non-existent log, the log will be

// created

//RETURNS: True if successful

//*************************************************************

public bool WriteToEventLog(string entry, string appName, EventLogEntryType eventType, string logName)

{

EventLog objEventLog = new EventLog();

try

{

if (!(EventLog.SourceExists(appName)))

{

EventLog.CreateEventSource(appName, LogName);

}

objEventLog.Source = appName;

objEventLog.WriteEntry(entry, eventType);

return true;

}

catch (Exception Ex)

{

return false;

}

}

}
