Running Dot Net project exe on Linux which makes use of System.Management to get USB Device information

问题

Hi, I have created a Dot Net application in C# to get USB Device Information like DeviceID, Caption, ClassGUID etc using System.Management Namespace. I'm using the ManagementObjectSearcher Method to fetch the value from Win32_DiskDrive. It's running fine on Windows. I want to run it on Linux machine. You can run Dot Net applications on Linux machine using Mono.

When i run my application's exe on Linux using Mono i get the following error:

    Missing method .ctor in assembly /home/dvimay11/USBCamInfoNew/Debug/System.Management.dll, type System.Reflection.AssemblySignatureKeyAttribute
Can't find custom attr constructor image: /home/dvimay11/USBCamInfoNew/Debug/System.Management.dll mtoken: 0x0a000009

Can anyone help me to fix this issue. I wanted to know how i can run my Dot Net exe on a Linux machine using the System.Management Namespace to retrieve information of USB Device

Thanks

If you look at the Mono Project Roadmap you'll find that System.Management is Windows specific and there are no plans to support it.

You could use SharpUsbLib instead which has support for USB under Linux.
