EntryWrittenEventArgs 类

定义

EntryWritten 事件提供数据。Provides data for the EntryWritten event.

public ref class EntryWrittenEventArgs : EventArgs
public class EntryWrittenEventArgs : EventArgs
type EntryWrittenEventArgs = class
    inherit EventArgs
Public Class EntryWrittenEventArgs
Inherits EventArgs
继承
EntryWrittenEventArgs

示例

下面的示例演示了EntryWrittenEventArgs构造函数。The following example demonstrates the EntryWrittenEventArgs constructor. 它会创建一个EventLog自定义对象, 并向其中写入一个条目。It creates a custom EventLog object and writes an entry into it. 然后, 它使用EntryWrittenEventArgs自定义EventLog中的第一个条目来创建对象。Then it creates an EntryWrittenEventArgs object using the first entry in the custom EventLog. 此对象用于通知消息。This object is used to notify a message.

#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 );
   }
