Get NDIS Version(s)?


I know that I could use Windows PowerShell

Get-netadapter|select Name, ndisversion

to pipe the results out to a text file, and parse the data from there, but that's sort of hacky. I was wondering if there's a way to get the same info using something more direct? i.e. WMI or a Framework class, etc.? I've Googled, but came up empty-handed.


Solution

  • All the NetAdapter powershell cmdlets are thin wrappers over WMI objects. So you can indeed use the Microsoft.Management.Infrastructure namespace directly.

    In this case, you'd enumerate instances of root\standardcimv2\MSFT_NetAdapter to look at their Name and DriverMajorNdisVersion fields.

    This isn't a complete tutorial on the MI APIs, but here's a pseudocode sketch of the idea:

    var session = CimSession.Create(. . .);
    foreach (var instance in session.EnumerateInstances(@"root\standardcimv2", "MSFT_NetAdapter")) {
        var name = instance.CimInstanceProperties["Name"].Value as string;
        var major = instance.CimInstanceProperties["DriverMajorNdisVersion"].Value as byte;
        WriteLine($"{name}: {major}.{minor}");
    }
