问题描述
我知道它已被问了很多,但我所经历的是当我将一个代码从之前的应用程序复制到具有相同设计的新应用程序时.net遇到了这个异常对象实例的事情。我以前的代码在设计上工作得很好,但在其他应用程序的相同设计上它给出了这个例外..谢谢你这里是我的代码
我试过的:
questions = Questions(Level.SelectedItem.ToString(),subjucts.SelectedItem.ToString()); //例外obj参考.. null exp
} thankxx

What I have tried:
questions = Questions(Level.SelectedItem.ToString(), subjucts.SelectedItem.ToString()); // exception here obj reference .. null exp
} thankxx
