EventLogEntry Class
Encapsulates a single record in the event log. This class cannot be inherited.
Assembly: System (in System.dll)
You usually will not create instances of EventLogEntry directly when working with the EventLog class. The Entries member of the EventLog class contains a collection of EventLogEntry instances, which you iterate over when reading by using the EventLogEntryCollection.Item class index member.
Windows 98, Windows Millennium Edition Platform Note: Event logs are not supported on Windows 98 or Windows Millennium.
The following code example demonstrates the use of the EventLogEntry class. In this example, a switch statement uses console input to search for event log entries for the specified event type. If a match is found, log entry source information is displayed at the console.
Imports System Imports System.Diagnostics Class MyEventlogClass Public Shared Sub Main() Dim myEventType As String = Nothing ' Associate the instance of 'EventLog' with local System Log. Dim myEventLog As New EventLog("System", ".") Console.WriteLine("1:Error") Console.WriteLine("2:Information") Console.WriteLine("3:Warning") Console.WriteLine("Select the Event Type") Dim myOption As Integer = Convert.ToInt32(Console.ReadLine()) Select Case myOption Case 1 myEventType = "Error" Case 2 myEventType = "Information" Case 3 myEventType = "Warning" Case Else End Select Dim myLogEntryCollection As EventLogEntryCollection = myEventLog.Entries Dim myCount As Integer = myLogEntryCollection.Count ' Iterate through all 'EventLogEntry' instances in 'EventLog'. Dim i As Integer For i = myCount - 1 To -1 Step -1 Dim myLogEntry As EventLogEntry = myLogEntryCollection(i) ' Select the entry having desired EventType. If myLogEntry.EntryType.ToString().Equals(myEventType) Then ' Display Source of the event. Console.WriteLine(myLogEntry.Source + " was the source of last "& _ "event of type " & myLogEntry.EntryType.ToString()) Return End If Next i End Sub 'Main End Class 'MyEventlogClass
