範例

下列範例示範如何使用 Task 屬性來定義事件工作。 此程式代碼範例是針對 類別提供的較大範例的 EventSource 一部分。

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
