.NET Framework Class Library
EntryWrittenEventArgs Constructor (EventLogEntry)
Initializes a new instance of the EntryWrittenEventArgs class with the specified event log entry.
Assembly: System (in System.dll)
Syntax
Visual Basic
Public Sub New ( _ entry As EventLogEntry _ )
C#
public EntryWrittenEventArgs(
EventLogEntry entry
)
Visual C++
public:
EntryWrittenEventArgs(
EventLogEntry^ entry
)
F#
new :
entry:EventLogEntry -> EntryWrittenEventArgs
Parameters
- entry
- Type: System.Diagnostics.EventLogEntry
An EventLogEntry that represents the entry that was written.
Examples
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.
Visual Basic
Imports System Imports System.Diagnostics Class MySample Public Shared Sub Main() Try Dim myNewLog As New EventLog() ' Create the source if it does not exist already. If Not EventLog.SourceExists("MySource") Then EventLog.CreateEventSource("MySource", "MyNewLog") Console.WriteLine("CreatingEventSource") End If myNewLog.Log = "MyNewLog" myNewLog.Source = "MySource" ' Write an entry to the EventLog. myNewLog.WriteEntry("The Latest entry in the Event Log") Dim myEntries As Integer = myNewLog.Entries.Count Dim entry As EventLogEntry = myNewLog.Entries(myEntries - 1) Dim myEntryEventArgs As New EntryWrittenEventArgs(entry) MyOnEntry(myNewLog, myEntryEventArgs) Catch e As Exception Console.WriteLine("Exception Raised" + e.Message) End Try End Sub 'Main Protected Shared Sub MyOnEntry(source As Object, e As EntryWrittenEventArgs) Dim myEventLogEntry As EventLogEntry = e.Entry If Not (myEventLogEntry Is Nothing) Then Console.WriteLine("Current message entry is: '" + _ myEventLogEntry.Message + "'") Else Console.WriteLine("The current entry is null") End If End Sub 'MyOnEntry End Class 'MySample
C#

Visual C++
