C# SuspendLayout一直给我一个期望

我正在尝试制作一个windows mobile应用程序，由于某种原因，SuspendLayout不断崩溃

它是如何崩溃的。我进入我的应用程序登录页面。然后我将手机旋转到横向并登录

然后我按下“OK”按钮，该按钮将关闭我访问的这个新表单。然后我回到登录页面，将手机旋转回纵向模式。然后我从表单（我刚刚关闭的表单）中得到一个expect

编辑

当方向改变或风景变为真时，我称之为。因为一个人可能会在登录表单上轮换，所以我的所有表单都必须调整以适应轮换

所以我有类似的东西

//login


form_load
{
   //figure out if they rotated this will be figured out by the SystemState.Change event that calls SetLayout that determine if they are in landscape or portrait.
   // set landscape property to true if they are in landscape mode.
}


// form1
form_load
{
  // generate default layout(formed for portrait)
  // if landscape property is set to true Call SetLayout
  // other wise just keep in default layout mode.

}

SetLayout()
{
  SuspendLayout();
  // code to determine if they are in portrait mode or landscape mode
  // once determined change sizes and stuff for new mode.
  // set static landscape property to true or false to use for future forms.
  ResumeLayout();
}

如果用户再次（或首次在该表单上）更改轮换，将调用SystemState.Change is事件。这将调用SetLayout（）。

我猜您在表单上注册了事件（“PhoneRotated”），但在关闭表单之前没有取消注册。因此，当事件触发时，关闭的表单会收到通知，但无法执行SuspendLayout，因为您已经关闭了它。

我认为您必须显示调用SuspendLayoutLaserCharger.LaserFired-=新事件处理程序（HandleLaserFireg）；所以你认为我应该删除SystemState.Change？你需要取消注册

orientationChange\u Change

。我不知道它具体处理什么事件。只需调用用于注册方向更改的同一行，但使用-=而不是+=

//login


form_load
{
   //figure out if they rotated this will be figured out by the SystemState.Change event that calls SetLayout that determine if they are in landscape or portrait.
   // set landscape property to true if they are in landscape mode.
}


// form1
form_load
{
  // generate default layout(formed for portrait)
  // if landscape property is set to true Call SetLayout
  // other wise just keep in default layout mode.

}

SetLayout()
{
  SuspendLayout();
  // code to determine if they are in portrait mode or landscape mode
  // once determined change sizes and stuff for new mode.
  // set static landscape property to true or false to use for future forms.
  ResumeLayout();
}
