In java, I could do this with the 'final' keyword. I don't see 'final' in C#. Is there a substitute?
在java中,我可以使用'final'关键字来完成此操作。我没有在C#中看到'final'。有替代品吗?

You're looking for the sealed keyword. It does exactly what the final keyword in Java does. Attempts to inherit will result in a compilation error.
您正在寻找密封关键字。它完全符合Java中的final关键字。尝试继承将导致编译错误。

Also be aware that "I don't think anybody will ever need to inherit from this" is not a good reason to use "sealed". Unless you've got a specific need to ensure that a particular implementation is used, leave the class unsealed.
还要注意“我认为任何人都不需要继承这个”并不是使用“密封”的好理由。除非您确实需要确保使用特定实现,否则请将该类保持为未密封状态。

As Joel already advised, you can use sealed instead of final in C#.
正如Joel已经建议的那样,你可以在C#中使用sealed而不是final。

The sealed modifier will do what final does in Java.
密封修饰符将完成Java中的最终操作。
Also, although this probably isn't what you're looking for in this situation, marking a class as static also keeps it from being inherited (it becomes sealed behind the scenes).
此外,虽然这可能不是您在这种情况下所寻找的,但将类标记为静态也会使其不被继承(它在幕后变得密封)。

The sealed keyword would work, but still you can derive from the class using reflection IIRC.
sealed密封关键字可以使用,但您仍然可以使用反射IIRC从类派生。
