CrystalDiskInfo项目的dll动态库的封装，方便其它语言使用。
我在做一个软件，需要读取电脑上所有连接的硬盘信息（主要是硬件型号和序列号）。项目是使用wpf开发的。 本来我是使用C#的wmi接口去获取的，代码如下：
ManagementObjectSearcher moSearcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (var mo in moSearcher.Get())
{
var diskinfo = new DiskInfo();
diskinfo.device_name = mo["Model"].ToString();
diskinfo.searial_num = mo["SerialNumber"].ToString();
}
但发现只能正确识别到STAT接口的硬盘，如果硬盘是通过nvme接口或者是usb连接的，就无法识别。 意外发现，有一款开源软件crystaldiskinfo识别的很准确。于时看了一眼他的代码，发现是用c++写的，里面的除了调用wmi接口外，还有很多和硬件驱动交互的逻辑。 于是我就想，能不能把crystaldiskinfo封装成一个dll库给c#调用，这样就能识别准确了。在参考了网上的资料后，我实现了这个库。
先下载编译好的(dll)[https://github.com/ftyszyx/CrystalDiskInfo_dll_lib/releases/tag/1.0.0],dll分32位和64位

使用visual studio打开DiskInfo.sln自行编译
如果是winform工程，需要增加清单文件app.manifest，并增加权限
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
具体可以上网查询
需要在清单文件app.manifest增加系统配置

新加获取smartinfo信息
[DllImport(dllname, CharSet = CharSet.Auto)]
static extern bool GetDiskInfo(IntPtr ptr, int index, ref SmartInfo info);
