我有一个windows form app动态生成
的tabpages，并且所有这些都是动态使用的controls，所以当生成并且不清理每次当前加上之前的 y 1 次时，我的应用程序将崩溃。我可以
全部，全部，收集
器，NULL THE memory 等等我能做的一切，但在我的 senario 中并没有清理， 当工作完成时，我正在与你共享代码 plx 一些帮助我datagridviewseventscontrolGDI objectsUser objectsobjectsobjectsdisposecontrolsclearcontrolsforcegarbageOBJECT ARRAYGDI ObjectsUserObjects
