How to add multiple lines of EventData to an EventLog in Windows?

I am able to currently create a Windows Event Log using the following code:

    string sSource;
    string sLog;
    string sEvent;
    sSource = "Sample App";
    sLog = "Application";
    sEvent = "Sample Event";

    if (!EventLog.SourceExists(sSource))
        EventLog.CreateEventSource(sSource,sLog);

EventLog.WriteEntry(sSource, sEvent, EventLogEntryType.Warning, 11111);

This creates a log in the Application Log. I want to add more than one line of data to the event in the event log so that while debugging I can parse the log directly for the problems. Also, I looked at some of the other logs in the Application logs and they seem to have a binary data field in them. I was not able to figure out as to how to write such a field because the above piece of code only adds an EventData field.

c# event-log

I tried using \n \t using EventLog.WriteEntry(). However I was not successful. I found a solution for this problem. We can use logger.WriteEvent()

//Object of eventinstance.

EventInstance eventInstance= new EventInstance(0, 0) {EntryType =       EventLogEntryType.Warning};
//Array of string.Event data node is generated based on the array size.

string [] eventLog = EventLogger.BuildEventLog("EventLogSamples.WriteEventSample2","test");

//Need to specify the source

EventLog log = new EventLog {Source = "source"};
log.WriteEvent(eventInstance, eventLog);

I was able to successfully write multiple eventData as shown below

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
  <Provider Name="test" /> 

  </System>
- <EventData>
  <Data>EventLogSamples.WriteEventSample2</Data> 
  <Data>test</Data> 
  </EventData>
  </Event>

Please let me know if you find any issues. PK (Prathap Kudupu)
