I have problem with debuging code. 我在调试代码时遇到问题。 I try to resolve one bug, but when I set breakpoint in catch statement and add watch to see details I get message from Visual Studio like below. 我试图解决一个错误，但是当我在catch语句中设置断点并添加监视以查看详细信息时，我从Visual Studio收到了如下消息。 Why? 为什么？ Can anyone explain me why is happens? 谁能解释我为什么会这样？

尝试在编译器设置中将“生成调试信息”设置为“完整”

如果您在循环或try或if块中声明变量，然后尝试从封闭的代码块或单独的代码块访问它，则经常发生此错误。
