C#如何获取硬盘中所有分区信息（DriveInfo.GetDrives()只能获取可见分区，windows 8 以上系统，那些安装时隐藏分区，或者是手工删除盘符的，都无法获取到

ilovecomputer66

继续求一下，第三方分区软件不知道调用什么系统API获取的

Hardware.info 可以，其他可以看官方说明。

[mw_shl_code=csharp,true]public override List GetDriveList()
{
        List list = new List();

能提供完整代码么？Driver类没有

对于不可见分区，执行 string queryString3 = str2 + ((obj2 != null) ? obj2.ToString() : null) + "'} WHERE AssocClass = Win32_LogicalDiskToPartition";

这句，都是获取不到任何结果的。最终效果，还是只获取了 C、D 2个可见的，隐藏分区拿不到

看我上面的图，不可见分区和没有盘符的分区是可以显示出来的。

我实测我的电脑。我SSD，安装win10，执行到获取分区信息的query3，系统隐藏分区，都没有信息，就C D 盘最终有

而且你的截图是用第三方库，我说的是你贴的那段不完整代码的，补全后的运行结果
