推荐答案

您看到什么错误?例外?其他状况?您需要在问题中添加一些其他上下文.但是，即使没有更好的描述，仍有一些事情仍然存在.

what's the error you see? Exception? Other condition? You need to add some additional context to your question. But there are a couple things that stick out even without a better description.

1. 在ZipFile类中使用using()子句；它是IDisposable的.

1. employ a using() clause with the ZipFile class; it is IDisposable.

似乎您尝试在调用.SaveAs()之前解压缩zip文件.如果我正确阅读了您的代码，则意味着ZipFile.Read()正在尝试读取尚未创建的文件.如果是这种情况，它将抛出一个 FileNotFoundException .我对此可能是错的.您提供的更多文字将有助于澄清.

It looks like you try to extract the zip file before you call .SaveAs(). If I read your code correctly, that means the ZipFile.Read() is trying to read a file that has not yet been created. If that is the case it will throw a FileNotFoundException. I may be wrong about this; more text from you would help clarify.
