推荐答案

这里是个主意:谁需要MDI?为什么要折磨自己并吓跑用户?

帮自己一个忙:完全不要使用MDI.没有设计，您可以更轻松地实现设计，并且质量更高.即使Microsoft也不鼓励使用MDI，实际上，Microsoft已将其从WPF中删除，并且几乎不支持它.更重要的是，如果您使用MDI，则会吓跑所有用户.只是不要.我可以解释该怎么办.

Here is the idea: who needs MDI, ever? Why torturing yourself and scaring out your users?

Do yourself a great favor: do not use MDI at all. You can do much easier to implement design without it, with much better quality. MDI is highly discouraged even by Microsoft, in fact, Microsoft dropped it out of WPF and will hardly support it. More importantly, you will scare off all your users if you use MDI. Just don''t. I can explain what to do instead.

似乎您正在窗体的Load事件中运行一些代码，这些代码都在主UI线程中运行，因此阻止了您的调用.

在单独的线程或BackgroundWorker中的每个表单内运行代码.

It seems you are running some code inside the Load event of the forms, which are all run in the main UI thread and thus blocking your calls.

Run the code inside each of the form in a separate Thread or a BackgroundWorker.
