例

次の例では、 EntryWrittenEventArgs コンストラクターを示します。カスタム EventLog オブジェクトを作成し、そのオブジェクトにエントリを書き込みます。次に、カスタム EventLogの最初のエントリを使用して、EntryWrittenEventArgs オブジェクトを作成します。このオブジェクトは、メッセージに通知するために使用されます。

using System;
using System.Diagnostics;

class MySample
{
    public static void Main()
    {
        try

            // 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.
