Příklady

Následující příklad ukazuje EntryWrittenEventArgs konstruktor. Vytvoří vlastní EventLog objekt a zapíše do něj záznam. Pak vytvoří EntryWrittenEventArgs objekt pomocí první položky ve vlastním EventLogobjektu . Tento objekt slouží k oznámení zprávy.

#using <System.dll>

using namespace System;
using namespace System::Diagnostics;

void MyOnEntry( Object^ source, EntryWrittenEventArgs^ e )
{
   if ( !e->Entry )
      Console::WriteLine( "A new entry is written in MyNewLog." );
}

int main()
{
   try
   {
      EventLog^ myNewLog = gcnew 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 = gcnew EntryWrittenEventArgs;
      MyOnEntry( myNewLog, myEntryEventArgs );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception Raised{0}", e->Message );
   }

Konstruktory

EntryWrittenEventArgs()	Inicializuje novou instanci EntryWrittenEventArgs třídy .
EntryWrittenEventArgs(EventLogEntry)	Inicializuje novou instanci EntryWrittenEventArgs třídy se zadanou položkou protokolu událostí.

Vlastnosti

Entry

Získá položku protokolu událostí, která byla zapsána do protokolu.

Metody

Equals(Object)	Určí, zda se zadaný objekt rovná aktuálnímu objektu. (Zděděno od Object)
GetHashCode()	Slouží jako výchozí hashovací funkce. (Zděděno od Object)
GetType()	Type Získá z aktuální instance. (Zděděno od Object)
MemberwiseClone()	Vytvoří mělkou kopii aktuálního Objectsouboru . (Zděděno od Object)
ToString()	Vrátí řetězec, který představuje aktuální objekt. (Zděděno od Object)
