那里从FlowLayoutPanel中删除的UserControls中没有被实际处理的众所周知的问题，导致最终的内存不足错误。



推荐的删除策略并且从FlowLayoutPanel处理UserControl是：

There are well-known problems with UserControls removed from a FlowLayoutPanel not being actually disposed of, resulting in, finally, out-of-memory errors.

The recommended strategy for removing and disposing UserControls from the FlowLayoutPanel is:

int yourIndex;

// get the Index value and assign it to 'yourIndex

Control toRemove = yourTableLayoutPanel.Controls[yourIndex];

yourTableLayoutPanel.Controls.Remove[i];

toRemove.Dipose();

如果你在FlowLayoutPanel中创建了很多破坏性的控件，我建议为了方便你保留一个字典<

If you are creating an destroying lots of Controls in the FlowLayoutPanel, I'd suggest that for convenience you keep a Dictionary<
