摘要有时需要获取电脑的相关信息。这时可以通过调用windows api的方式，进行获取。 方法可以通过在powershell中 通过下面的命令进行查询，然后可以通过c#调用获取需要的信息。 gwmi + windows api? 如图所示
对应的c#代码为

这里只是枚举了部分api，有兴趣的可以查看其它的windows api 并通过power shell查看，然后转化为c# 代码即可。 这里需要注意，硬盘容量在转化的时候需要除以1000，而不是1024.但内存是需要除以1024的，这点需要注意。 转化方法：
ToGB( size,= String[] { ,,,,, i = (size >=/=++ Math.Round(size) +
