C#到VB AddressOf

Question

比起c#，我更像一个VB的家伙，所以我在c#中有这样的代码：

    MouseGesture _mg;

    public Form1()
    {
        InitializeComponent();

        // b) Load a file with the commands and keys once in your application
        MouseGestureData.Instance.Commands.ReadFile( 
            Environment.CurrentDirectory + @"\MouseGestureCommands.xml" );

        // c) For each Form you want to use mouse gestures...
        _mg = new MouseGesture( this, null ); 
        _mg.MouseGestureEntered += new MouseGestureEventHandler( 
            OnMouseGestureEntered );
    }

    private void OnMouseGestureEntered( object sender, MouseGestureEventArgs e )
    {
        // d) In your registered MouseGestureEventHandler, handle the commands
        // you want
        MessageBox.Show( string.Format( "OnMouseGestureEntered:\n" +
                                        "   Command:\t{0}\n" +
                                        "   Key:\t\t{1}\n" +
                                        "   Control:\t\t{2}\n" +
                                        "   Bounds:\t\t{3}", 
                                        e.Command, e.Key, e.Control,
                                        e.Bounds.ToString() ) );
    }

这是我可以从VB.net得到的：

Private _mg As MouseGesture

Public Sub New()
    InitializeComponent()

    MouseGestureData.Instance.Commands.ReadFile(Environment.CurrentDirectory + "\MouseGestureCommands.xml")

    _mg = New MouseGesture(Me, Nothing)
    _mg.MouseGestureEntered += New MouseGestureEventHandler(AddressOf OnMouseGestureEntered)
End Sub

Private Sub OnMouseGestureEntered(sender As Object, e As MouseGestureEventArgs)
    ' d) In your registered MouseGestureEventHandler, handle the commands
    ' you want
    MessageBox.Show(String.Format("OnMouseGestureEntered:" & vbLf & "   Command:" & vbTab & "{0}" & vbLf & "   Key:" & vbTab & vbTab & "{1}" & vbLf & "   Control:" & vbTab & vbTab & "{2}" & vbLf & "   Bounds:" & vbTab & vbTab & "{3}", e.Command, e.Key, e.Control, e.Bounds.ToString()))
End Sub

问题在于_mg.MouseGestureEntered这句话的意思是：

公共事件MouseGestureEntered(发件人作为对象，e作为DcamMouseGesture.MouseGestureEventArgs)‘是一个事件，不能直接调用。使用“RaiseEvent”语句引发事件。

为了让它在VB中工作，我需要把它转换成什么？

Answer 1

而不是：

_mg.MouseGestureEntered += New MouseGestureEventHandler(AddressOf OnMouseGestureEntered)

试着使用：

AddHandler _mg.MouseGestureEntered, AddressOf OnMouseGestureEntered
