C# DeviceIoControl返回带有IOCTL\u SCSI\u PASS\u的1306

我正在尝试将DeviceIoControl与C中的IOCTL_SCSI_PASS_THROUGH控制代码一起使用。 但是DeviceIoControl返回错误代码1306

我想做的是获得INTEL NVMe SSD的S.M.A.R.T

我试着参考一下Crystal Disk Info的源代码

它在C或C++中成功运行。 以下源代码的问题在哪里

模糊的错误代码，但谷歌搜索效果很好。告诉您Length属性是错误的。它在32位模式下为44，在64位模式下为56。项目>属性>生成选项卡，“首选32位”复选框。喜欢Marshal.SizeOf（）。您是否查看了pinvoke示例代码：@HansPassant我根据您的评论进行了尝试，结果成功了。请回答这个问题。谢谢：）@anonymq你能解决这个问题吗？我目前面临着一个挑战：通过Powershell读取NVMe设备的智能数据，并寻找一些好的C#模板将其嵌入PS脚本。
