这些错误：

I hope you can help me .


these ERROR :

PictureBox.Children.Add(_videoViewerWpf); 'System.Windows.Forms.PictureBox' does not contain a definition for 'Children' and no extension method 'Children' accepting a first argument of type 'System.Windows.Forms.PictureBox' could be found (are you missing a using directive or an assembly reference?)

HorizontalAlignment = HorizontalAlignment.Stretch, horizontalalignment' is an ambiguous reference between 'system.windows.forms.horizontalalignment'

Background = Brushes.Black Background = Brushes.Black cannot implicitly convert type 'system.drawing.brush' to 'system.windows.media.brush'

我尝试了什么：



我试图解决这个错误，但我不能在Children.Add（_videoViewerWpf）中出现错误。 Background = Brushes.Black AND Horizo​​ntalAlignment = Horizo​​ntalAlignment.Stretch，

What I have tried:

I tried to solve this ERROR but I can't I have ERROR in Children.Add(_videoViewerWpf); Background = Brushes.Black AND HorizontalAlignment = HorizontalAlignment.Stretch,

推荐答案

错误消息是清楚的，请查看图片盒类（System.Windows.Forms） [ ^ ] 。没有儿童属性。

The error message is queite clear, look at the documentation for PictureBox Class (System.Windows.Forms)[^]. There is no Children property.
