Contoh

Contoh berikut menunjukkan cara menggunakan Opcode properti untuk menentukan kode operasi. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan untuk EventSource kelas .

[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

[Event(6, Opcode = EventOpcode.Stop, Task = Tasks.DBQuery, Keywords = Keywords.DataBase, Level = EventLevel.Informational)]
public void DBQueryStop() { WriteEvent(6); }

<[Event](6, Opcode:=EventOpcode.Stop, Task:=Tasks.DBQuery, Keywords:=Keywords.DataBase, Level:=EventLevel.Informational)> _
Public Sub DBQueryStop()
    WriteEvent(6)
End Sub
