将事件委托从C＃转换为VB.NET

Question

尝试使用各种在线转换器将此代码转换为VB.NET但没有工作（在事件处理程序声明中出错）。我正在使用VS 2012和.Net 4.5。有什么想法吗？

readonly Action<IDialogManager, Action<bool>> closeCheck;

public void Execute(ActionExecutionContext context) {
        closeCheck(Shell.Dialogs, result => Completed(this, new ResultCompletionEventArgs { WasCancelled = !result }));
    }

public event EventHandler<ResultCompletionEventArgs> Completed = delegate { };

Answer 1

我在LinqPad中创建了虚拟类型并得到了这个：

ReadOnly closeCheck As Action(Of IDialogManager, Action(Of Boolean))

Public Sub Execute(ByVal Context As ActionExecutionContext)
    closeCheck(Shell.Dialogs, Sub(Result) RaiseEvent Completed(Me, New ResultCompletionEventArgs With { .WasCancelled = Not Result }))
End Sub

Public Event Completed As EventHandler(Of ResultCompletionEventArgs)
