Interacting with the Hardware using C#

Get OS, Service Pack Information

 

Use the System.Environment.OSVersion

OperatingSystem os = System.Environment.OSVersion;
Console.WriteLine("Platform: {0}", os.Platform);
Console.WriteLine("Service Pack: {0}", os.ServicePack);
Console.WriteLine("Version: {0}", os.Version);
Console.WriteLine("VersionString: {0}", os.VersionString);
Console.WriteLine("CLR Version: {0}", System.Environment.Version);

This produces the following output (on my Windows 7 system):

 

Platform: Win32NT

Service Pack:

Version: 6.1.7600.0

VersionString: Microsoft Windows NT 6.1.7600.0

CLR Version: 4.0.21006.1

 

The version information is in a struct, so you can make decisions based on version or subversion values.
