Ejemplos

En el ejemplo siguiente se muestra cómo usar la Keywords propiedad para definir palabras clave de evento. Este ejemplo de código es parte de un ejemplo más grande proporcionado para la clase EventSource.

public static class Keywords
{
    public const EventKeywords Page = (EventKeywords)1;
    public const EventKeywords DataBase = (EventKeywords)2;
    public const EventKeywords Diagnostic = (EventKeywords)4;
    public const EventKeywords Perf = (EventKeywords)8;
}

Public Class Keywords
    Public Const Page As EventKeywords = CType(1, EventKeywords)
    Public Const DataBase As EventKeywords = CType(2, EventKeywords)
    Public Const Diagnostic As EventKeywords = CType(4, EventKeywords)
    Public Const Perf As EventKeywords = CType(8, EventKeywords)
End 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(3, Message = "loading page {1} activityID={0}", Opcode = EventOpcode.Start,
    Task = Tasks.Page, Keywords = Keywords.Page, Level = EventLevel.Informational)]
public void PageStart(int ID, string url) { if (IsEnabled()) WriteEvent(3, ID, url); }

<[Event](3, Message:="loading page {1} activityID={0}", Opcode:=EventOpcode.Start, Task:=Tasks.Page, Keywords:=Keywords.Page, Level:=EventLevel.Informational)> _
Public Sub PageStart(ByVal ID As Integer, ByVal url As String)
    If IsEnabled() Then
        WriteEvent(3, ID, url)
    End If
End Sub
