如何获得本机.NET Framework真实版本

VS里看,我的.NET是3.5SP1的,这是正确的
但是System.Environment.Version.ToString()缺是2.0的,这个明显不对

什么方法能得到3.5SP1这个值

前提:机器上至少装了2.0版本的.NET,所以不存在.NET存不存在的问题

用GetFileVersion方法获取，这是mscoree.dll中的方法，是个动态链接库，非托管方法。关于mscoree.dll比较复杂，它可以说是CLR的老板，mscoree负责指定本地哪个版本的CLR来运行当前入口Assembly，也就是exe。你可以在msdn中查GetFileVersion，调用它要通过Pinvoke的。你的程序如果用了GetFileVersion，那么发布的时候就必须把mscoree.dll也拷贝进去了，虽然用户机器上只要装了.net framework肯定在System32下有。
