Exemplos

O exemplo seguinte cria a fonte MySource se esta ainda não existir, e escreve uma entrada no registo MyNewLogde eventos .

using System;
using System.Diagnostics;
using System.Threading;

class MySample{

    public static void Main(){

        // Create the source, if it does not already exist.
        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("CreatedEventSource");
            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;
        }

        // Create an EventLog instance and assign its source.
        EventLog myLog = new EventLog();
        myLog.Source = "MySource";

        // Write an informational entry to the event log.
        myLog.WriteEntry("Writing to event log.");

Observações

Antes de chamar WriteEntry, especifique a Source propriedade da EventLog instância. Se estiver apenas a ler Entries do log, pode especificar apenas as Log propriedades e.MachineName

A tabela seguinte mostra os valores iniciais das propriedades para uma instância de EventLog.

Observações

Esta sobrecarga define a Log propriedade para o logName parâmetro. Antes de chamar WriteEntry, especifique a Source propriedade da EventLog instância. Se estiver apenas a ler Entries do log, pode especificar apenas as Log propriedades e.MachineName

Se a fonte que especifica na Source propriedade for única em relação a outras fontes no computador, uma chamada subsequente cria WriteEntry um registo com o nome especificado, caso ainda não exista.

Observações

Este construtor define a Log propriedade para o logName parâmetro, a MachineName propriedade para o machineName parâmetro e a Source propriedade para o source parâmetro. A Source propriedade é necessária ao escrever num registo de eventos. No entanto, se estiver apenas a ler um registo de eventos, apenas as Log propriedades e MachineName são necessárias (desde que o registo de eventos no servidor já tenha uma fonte associada). Se estiveres apenas a ler do registo de eventos, outra sobrecarga do construtor pode ser suficiente.

A tabela seguinte mostra os valores iniciais das propriedades para uma instância de EventLog.
