Voorbeelden

In het volgende voorbeeld ziet u de EntryWrittenEventArgs constructor. Er wordt een aangepast EventLog object gemaakt en er wordt een vermelding in geschreven. Vervolgens wordt er een EntryWrittenEventArgs object gemaakt met behulp van de eerste vermelding in de aangepaste EventLogvermelding. Dit object wordt gebruikt om een bericht op de hoogte te stellen.

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"))
            {
                // An event log source should not be created and immediately used.
                // There is a latency time to enable the source, it should be created
                // prior to executing the application that uses the source.
                // Execute this sample a second time to use the new source.
                EventLog.CreateEventSource("MySource", "MyNewLog");
                Console.WriteLine("CreatingEventSource");
                Console.WriteLine("Exiting, execute the application a second time to use the source.");
                // The source is created.  Exit the application to allow it to be registered.
                return;
            }
            // 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 =
