推荐答案

.NET Framework中没有这样的魔术函数.您必须自己编写魔术".

您要做的就是在打印文档时将带有当前日期的值写入注册表.应用启动时，只需将当前日期与注册表中存储的日期进行比较即可.如果日期匹配，则说明您已经打印了文档.如果不是这样，那应该很明显.

There is no magic function like this in the .NET Framework. You have to write the "magic" yourself.

ALl you have to do is write a value to the registry with the current date when you print the document. When your app starts, all it has to do is compare the current date to the one stored in the registry. If the dates match, you''ve already printed document. If not, well, that should be obvious.
