将C＃代码移植到vb.net - eventhandler

Question

我正在尝试从C＃移植以下代码，但不知道！它将如何转换为事件处理程序

C＃

Select+=new EventHandler(OnSelectEvent);
if (!isMainMenuItem)
    {
        OwnerDraw=true;
        MeasureItem+=new MeasureItemEventHandler(OnMeasureItem);
        DrawItem+=new DrawItemEventHandler(OnDrawItem);
    }

移植代码：

  [Select] += New EventHandler(AddressOf OnSelectEvent)

    If Not isMainMenuItem Then
        OwnerDraw = True
        ' AddHandler Menuitem.select, new measuritemeventhandler(addressof onmeasureitem)
        MeasureItem += New MeasureItemEventHandler(AddressOf OnMeasureItem)
        DrawItem += New DrawItemEventHandler(AddressOf OnDrawItem)
    End If

Answer 1

+ =标记不能在VB.net中使用，您必须使用AddHandler命令。 它的语法不一样。

AddHandler MeasureItem, AddressOf OnMeasureItem
