c# - 从 Obj C 到 C# 的转换

Question

我正在尝试将这段代码转换为 C#，代码来自 Apple 的 documentation

NSDictionary* info = [aNotification userInfo];

CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size; 

UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);

scrollView.contentInset = contentInsets;

scrollView.scrollIndicatorInsets = contentInsets;

CGRect aRect = self.view.frame;

aRect.size.height -= kbSize.height;

if (!CGRectContainsPoint(aRect, activeField.frame.origin) ) {

    CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y-kbSize.height);

    [scrollView setContentOffset:scrollPoint animated:YES];

到目前为止，这是我的尝试，我卡在了 CGRectValue。

                    NSDictionary info = n.UserInfo;

        SizeF kbSize = ((RectangleF)info[UIKeyboard.FrameBeginUserInfoKey]).Size;

        UIEdgeInsets contentInsets = new UIEdgeInsets(0.0f, 0.0f, kbSize.Height, 0.0f);

        this.uiScrollView.ContentInset = contentInsets;
        this.uiScrollView.ScrollIndicatorInsets = contentInsets;

        RectangleF aRect = this.View.Frame;

        aRect.Size.Height -= kbSize.Height;

        if(!aRect.Contains(_currentField.Frame))
        {
            PointF scrollPoint = new PointF(0.0f, _currentField.Frame.Y - kbSize.Height);
            this.uiScrollView.SetContentOffset(scrollPoint, true);
        }

我可能没有使用正确的类型，有人可以帮助我，或者一些替代代码做类似的事情。 谢谢

想通了:

((NSValue)info[UIKeyboard.FrameBeginUserInfoKey]).RectangleFValue.Size

那应该行得通。虽然我不能让它像我想要的那样工作，但那行代码实际上会编译并转换为 Obj C 代码。
