EntryWrittenEventArgs Class
.NET Framework 3.0
Provides data for the EntryWritten event.
Namespace: System.Diagnostics
Assembly: System (in system.dll)
Assembly: System (in system.dll)
The following example demonstrates the EntryWrittenEventArgs constructor. It creates a custom EventLog object and writes an entry into it. Then it creates an EntryWrittenEventArgs object using the first entry in the custom EventLog. This object is used to notify a message.
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(); MyOnEntry(myNewLog, myEntryEventArgs); } catch (Exception e) { Console.WriteLine("Exception Raised" + e.Message); } } protected static void MyOnEntry(Object source, EntryWrittenEventArgs e) { if (e.Entry == null) Console.WriteLine("A new entry is written in MyNewLog."); } }

public static void main(String[] args)

try {
EventLog myNewLog = new EventLog();
myNewLog.set_Log("MyNewLog");
myNewLog.set_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.get_Entries().get_Count();
EventLogEntry entry = myNewLog.get_Entries().
get_Item((myEntries - 1));
EntryWrittenEventArgs myEntryEventArgs = new EntryWrittenEventArgs();
MyOnEntry(myNewLog, myEntryEventArgs);
}
catch (System.Exception e) {
Console.WriteLine("Exception Raised" + e.get_Message());
}
} //main
private static void MyOnEntry(Object source, EntryWrittenEventArgs e)
{
if (e.get_Entry() == null) {
Console.WriteLine("A new entry is written in MyNewLog.");
}
} //MyOnEntry
} //MySample
