The following example shows how to use the Level property to specify event levels. This code example is part of a larger example provided for the EventSource class.

[Event(1, Message = "Application Failure: {0}", Level = EventLevel.Error, Keywords = Keywords.Diagnostic)]
public void Failure(string message) { WriteEvent(1, message); }

<[Event](1, Message:="Application Failure: {0}", Level:=EventLevel.Error, Keywords:=Keywords.Diagnostic)> _
Public Sub Failure(ByVal message As String)
    WriteEvent(1, message)
End Sub

[Event(2, Message = "Starting up.", Keywords = Keywords.Perf, Level = EventLevel.Informational)]
public void Startup() { WriteEvent(2); }

<[Event](2, Message:="Starting up.", Keywords:=Keywords.Perf, Level:=EventLevel.Informational)> _
Public Sub Startup()
    WriteEvent(2)
End Sub

[Event(7, Level = EventLevel.Verbose, Keywords = Keywords.DataBase)]
public void Mark(int ID) { if (IsEnabled()) WriteEvent(7, ID); }

<[Event](7, Level:=EventLevel.Verbose, Keywords:=Keywords.DataBase)> _
Public Sub Mark(ByVal ID As Integer)
    If IsEnabled() Then
        WriteEvent(7, ID)
    End If
End Sub
