[NET] Get Operating system product line

[Zxian]

So I'm writing this little app in .NET, but I'm having some troubles getting the Operating System type. I can already get the OS version (Windows 2000/XP, etc), but I need to get Home/Pro etc.

System.OperatingSystem osInfo = System.Environment.OSVersion;
string windowsVersion = "Windows Version: ";
int servicePack = 0;

// Determine the platform.
switch (osInfo.Platform)
{
    case System.PlatformID.Win32Windows:
        MessageBox.Show("This program is not supported on this version of Windows.");
        System.Environment.Exit(0);
        break;

    case System.PlatformID.Win32NT:

        switch (osInfo.Version.Major)
        {
            case 3:
            case 4:
                MessageBox.Show("This program is not supported on this version of Windows.");
                System.Environment.Exit(0);
                break;
            case 5:
                if (osInfo.Version.Minor == 0)
                {
                    windowsVersion += "Windows 2000";
                    windowsVersion += osInfo.ServicePack.ToString();
                    MessageBox.Show("Windows 2000");
                }
                else
                {
                    windowsVersion += "Windows XP ";
                    OSVERSIONINFOEX osVersion = new OSVERSIONINFOEX();
                    GlobalFunctions.GetVersionEx(osVersion);
                    switch(osVersion.SuiteMask)
                    {
                        case 0x00000200:
                            windowsVersion += "Home Edition ";
                            break;
                        default:
                            windowsVersion += "Professional ";
                            break;
                    }
                    switch (osInfo.ServicePack)
                    {
                        case "Service Pack 2":
                            windowsVersion += "Service Pack 2";
                            servicePack = 2;
                            break;
                        case "Service Pack 1":
                            windowsVersion += "Service Pack 1";
                            servicePack = 1;
                            break;
                    }
                }
                break;
        } break;
}

I'm importing the GetVersionEx function from kernel32.dll. I'm guessing the problem comes from the enumerated data types that aren't properly passed over...

Any ideas?

Once you figure it out, I claim first dibs on beta testing!

I did this in Vb.net 2005 on Vista so I do not know if it is what you want.

If this is what you need here are the Project Files for this.

Thanks GSM - that's pretty much exactly what I want. I just don't know how to turn that VB.NET code into C#.NET...

The My namespace doesn't exist in .NET, and I've yet to find an equivalent. That's why I moved towards importing the API import (as per jcarle's suggestion over MSN).

EDIT - I think I got it actually... I sent a spoof program that just spits out information to a friend of mine, and got him to send me back the info.
