示例

以下示例演示构造 EntryWrittenEventArgs 函数。 它创建一个自定义 EventLog 对象，并将一个条目写入其中。 然后使用自定义EntryWrittenEventArgs中的第一个条目创建对象EventLog。 此对象用于通知消息。

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 =
                                 new EntryWrittenEventArgs();
