推荐答案

在.NET中唯一的办法我能想到的将是Excel自动运行，并不断尝试进入不同的密码，但它可能会更好，试图弄个一些应用程序，可能会多一点有效地为你做的。 这是假设你已经使用了一些简单的单词作为密码，因为据我所知，没有捷径，因此将不得不做一个字典攻击，所以如果你已经使用了艰难的密码可能需要很长的时间发现并非如此。

The only way in .Net I can think of would be to automate Excel and keep trying to enter different passwords, but it might be better to try to get hold of some app that might do that for you a bit more efficiently. This is assuming that you've used some simple word as the password, as far as I know there's no shortcuts so it'll have to do a dictionary attack, so if you've used a difficult password it might take a very long time to find otherwise.
