ManagementObject Class not showing up in System.Management namespace

\"The type or namespace name \'ManagementObject\' could not be found\" Err

Answer 1

Right-click References on the right and manually add System.Management. Even though I included it in the using statement I still had to do this. Once I did, all worked fine.

Answer 2

Have you added a reference to the System.Management assembly?

Answer 3

You need to add a reference to System.Management.dll to your project.

You can see System.Management.Instrumentation without adding a reference to System.Management.dll because it is included in a different library (System.Core.dll, which is included as a reference automatically), but you cannot access the other types contained by that namespace without explicitly adding a reference to the System.Management.dll library.

Answer 4

I think the problem is there is no WMI object for Win32_LogicalDisk.DeviceID=\"C:\". Try to replace:

ManagementObject disk = new ManagementObject("Win32_LogicalDisk.DeviceID=\"C:\"");

with:

ManagementObject disk = new ManagementObject("Win32_LogicalDisk");

and then to step through each field:

foreach (ManagementObject o in disk.Get()){
    //Do what ever you need here.... For example:  
    Console.WriteLine(o.ToString());
}

Answer 5

In Solution Explorer, right click on References, then Add Reference ... and under Framework, you should activate the System.Management framework.
