EntryWrittenEventArgs Class

Provides data for the EntryWritten event.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public class EntryWrittenEventArgs : EventArgs
public class EntryWrittenEventArgs extends EventArgs
public class EntryWrittenEventArgs extends EventArgs

The following example demonstrates the EntryWrittenEventArgs constructor. It creates a custom EventLog object and writes an entry into it. Then it creates an EntryWrittenEventArgs object using the first entry in the custom EventLog. This object is used to notify a message.

using System;
using System.Diagnostics;

   class MySample
   {
      public static void Main()
      {
         try
         {
            EventLog myNewLog = new EventLog();
            myNewLog.Log = "MyNewLog";
            myNewLog.Source="MySource";
            // Create the source if it does not exist already.
            if(!EventLog.SourceExists("MySource"))
            {
               EventLog.CreateEventSource("MySource", "MyNewLog");
               Console.WriteLine("CreatingEventSource");
            }
               // Write an entry to the EventLog.
               myNewLog.WriteEntry("The Latest entry in the Event Log");
            int myEntries = myNewLog.Entries.Count;
            EventLogEntry entry =myNewLog.Entries[myEntries-1];
            EntryWrittenEventArgs myEntryEventArgs=
                                 new EntryWrittenEventArgs();
            MyOnEntry(myNewLog,myEntryEventArgs);
         }
         catch(Exception e)
         {
            Console.WriteLine("Exception Raised" +e.Message);
         }
      }
      protected static void MyOnEntry(Object source, EntryWrittenEventArgs e)
      {
         if(e.Entry == null)
            Console.WriteLine("A new entry is written in MyNewLog.");
      }
   }
