The following example shows how to use the Task property to define event tasks. This code example is part of a larger example provided for the EventSource class.
public static class Tasks
{
public const EventTask Page = (EventTask)1;
public const EventTask DBQuery = (EventTask)2;
}
Public Class Tasks
Public Const Page As EventTask = CType(1, EventTask)
Public Const DBQuery As EventTask = CType(1, EventTask)
End Class
[Event(4, Opcode = EventOpcode.Stop, Task = Tasks.Page, Keywords = Keywords.Page, Level = EventLevel.Informational)]
public void PageStop(int ID) { if (IsEnabled()) WriteEvent(4, ID); }
<[Event](4, Opcode:=EventOpcode.Stop, Task:=Tasks.Page, Keywords:=Keywords.Page, Level:=EventLevel.Informational)> _
Public Sub PageStop(ByVal ID As Integer)
If IsEnabled() Then
WriteEvent(4, ID)
End If
End Sub
[Event(5, Opcode = EventOpcode.Start, Task = Tasks.DBQuery, Keywords = Keywords.DataBase, Level = EventLevel.Informational)]
public void DBQueryStart(string sqlQuery) { WriteEvent(5, sqlQuery); }
<[Event](5, Opcode:=EventOpcode.Start, Task:=Tasks.DBQuery, Keywords:=Keywords.DataBase, Level:=EventLevel.Informational)> _
Public Sub DBQueryStart(ByVal sqlQuery As String)
WriteEvent(5, sqlQuery)
End Sub
