EntryWrittenEventArgs.EntryWrittenEventArgs(EventLogEntry) Constructor

Initializes a new instance of the EntryWrittenEventArgs class with the specified event log entry.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public EntryWrittenEventArgs (
	EventLogEntry entry
)
public EntryWrittenEventArgs (
	EventLogEntry entry
)
public function EntryWrittenEventArgs (
	entry : EventLogEntry
)
Not applicable.

Parameters

entry

An EventLogEntry that represents the entry that was written.

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
        {

            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");
