如何将下面的C＃代码转换成VB.NET代码？急
namespace Morell.GroupPanel
{
public delegate void PropChangeHandler(TabPage tabPage, Property prop, object oldValue);
public enum Property
{
Text,
ImageIndex
}
}

namespace Morell.GroupPanel
{
public class GroupPanel : System.Windows.Forms.UserControl
{
private void StartEdit(object sender, EventArgs e)
{
this.Capture = true;
}
}
}

namespace Morell.GroupPanel
{
[ToolboxItem(false)]public class TabPage : Panel
{
public event PropChangeHandler PropertyChanged;
public event EventHandler StartEdit;

public void OnPropertyChanged(Property prop, object oldValue)
{
// Is the event registered
if (PropertyChanged != null)
// Raise the event
PropertyChanged(this, prop, oldValue);
}

Public Sub BeginEdit()
If Not (StartEdit Is Nothing) Then
StartEdit(Me, New EventArgs())
End If
End Sub
}
}




[解决办法]
Namespace Morell.GroupPanel
Public delegate void PropChangeHandler(TabPage tabPage, Property prop, Object oldValue)
Public Enum Property

Public Class GroupPanel
Inherits System.Windows.Forms.UserControl
Private Sub StartEdit(ByVal sender As Object, ByVal e As EventArgs)
Me.Capture = True

End Class
End Namespace

Namespace Morell.GroupPanel
(ToolboxItem(False))Public Class TabPage
Inherits Panel
Public event PropChangeHandler PropertyChanged
Public event EventHandler StartEdit

Public Sub OnPropertyChanged(ByVal prop As Property, ByVal oldValue As Object)
' Is the event registered
If Not PropertyChanged Is Nothing Then
' Raise the event
PropertyChanged(this, prop, oldValue)
End If
End Sub

Public Sub BeginEdit()
