推荐答案

嗨donvn，

Hi donvn,

我读了你的帖子和你提供的链接，基于异常，我认为它不是WPF问题，更相对的WindowsForms，我建议您可以在WinForm论坛上发布您的问题以获得解决方案，链接是：

I read your post and the link you provide, based on the exception, I think it is not a WPF issue, more relative WindowsForms, I suggest that you could post your issue on WinForm forum to get the solution, the link is:
