推荐答案
这是结束了工作的解决方案:
This is the solution that ended up working:
public System.Windows.Forms.Control FindFocusedControl()
{
return FindFocusedControl(this);
}
public static System.Windows.Forms.Control FindFocusedControl(System.Windows.Forms.Control container)
{
foreach (System.Windows.Forms.Control childControl in container.Controls)
{
if (childControl.Focused)
{
return childControl;
}
}
foreach (System.Windows.Forms.Control childControl in container.Controls)
{
System.Windows.Forms.Control maybeFocusedControl = FindFocusedControl(childControl);
if (maybeFocusedControl != null)
{
return maybeFocusedControl;
}
}
return null; // Couldn't find any, darn!
}
