I want to p/invoke the windows api function ChangeServiceConfig2 for setting the description and/or "start delayed" flag for a service (and possibly more). Special thing about this is that it takes a pointer to different structures depending on what you want to change.
我希望p/调用windows api函数ChangeServiceConfig2来设置服务的描述和/或“开始延迟”标志(可能更多)。它的特别之处在于，它使用指针指向不同的结构，这取决于你想要改变什么。
For example, to change the description text of a service, you'll need to point it to a SERVICE_DESCRIPTION structure and to change the delayed flag you'll point to a SERVICE_DELAYED_AUTO_START_INFO structure.
例如，要更改服务的描述文本，您需要将其指向SERVICE_DESCRIPTION结构，并更改延迟标志，您将指向SERVICE_DELAYED_AUTO_START_INFO结构。
I have solved this by creating several overloads of the api function like this:
我通过创建api函数的多个重载解决了这个问题:
private static extern bool ChangeServiceConfig2(IntPtr hService, int dwInfoLevel, [MarshalAs(UnmanagedType.Struct)] ref SERVICE_DESCRIPTION lpInfo);
private static extern bool ChangeServiceConfig2(IntPtr hService, int dwInfoLevel, [MarshalAs(UnmanagedType.Struct)] ref SERVICE_DELAYED_AUTO_START_INFO lpInfo);
I want to ask if there's a better solution that wouldn't require another dozen or so overloads if I want to completely prototype it?
我想问，如果我想要完全原型化，是否有更好的解决方案，不需要再做十几次重载?

Just took a look inside the code of the ServiceInstaller class and found out that they're doing it the same way, so it cannot be all wrong...
只要看一下ServiceInstaller类的代码，就会发现它们的做法是一样的，所以不可能都是错的……
Still open for suggestions, though.
尽管如此，仍然可以接受建议。
