Examples

The following code example uses the OperatingSystem object to display information about the runtime operating system.

using System;

public class Example
{
   public static void Main()
   {
      var os = Environment.OSVersion;
      Console.WriteLine("Current OS Information:\n");
      Console.WriteLine("Platform: {0:G}", os.Platform);
      Console.WriteLine("Version String: {0}", os.VersionString);
      Console.WriteLine("Version Information:");
      Console.WriteLine("   Major: {0}", os.Version.Major);
      Console.WriteLine("   Minor: {0}", os.Version.Minor);
      Console.WriteLine("Service Pack: '{0}'", os.ServicePack);
   }
}
// If run on a Windows 8.1 system, the example displays output like the following:
//       Current OS Information:
//
//       Platform: Win32NT
//       Version String: Microsoft Windows NT 6.2.9200.0
//       Version Information:
//          Major: 6
//          Minor: 2
//       Service Pack: ''
// If run on a Windows 7 system, the example displays output like the following:
//       Current OS Information:
//
//       Platform: Win32NT
//       Version String: Microsoft Windows NT 6.1.7601 Service Pack 1
//       Version Information:
//          Major: 6
//          Minor: 1
//       Service Pack: 'Service Pack 1'
Module Example
   Public Sub Main()
      Dim os As OperatingSystem = Environment.OSVersion
      Console.WriteLine("Current OS Information:")
      Console.WriteLine()
      Console.WriteLine("Platform: {0:G}", os.Platform)
      Console.WriteLine("Version String: {0}", os.VersionString)
      Console.WriteLine("Version Information:")
      Console.WriteLine("   Major: {0}", os.Version.Major)
      Console.WriteLine("   Minor: {0}", os.Version.Minor)
      Console.WriteLine("Service Pack: '{0}'", os.ServicePack)
   End Sub

Remarks

The OperatingSystem class contains information about an operating system.

For information about the current runtime operating system, retrieve the OperatingSystem object returned by the System.Environment.OSVersion property. For a list of Windows operating system versions and their corresponding version numbers returned by the Version and VersionString properties and the ToString method, see Operating System Version on the Windows Dev Center.

By design, the OperatingSystem class is not a general purpose means of describing an operating system, and you cannot derive a more inclusive type from the OperatingSystem class. If you need a type to contain other information about an operating system, create your own type, then include a field of type OperatingSystem and any additional fields, properties, or methods that you require.

Constructors

Operating​System(​Platform​ID, ​Version)

Initializes a new instance of the OperatingSystem class, using the specified platform identifier value and version object.

Properties

Platform

Gets a PlatformID enumeration value that identifies the operating system platform.

Service​Pack

Gets the service pack version represented by this OperatingSystem object.

Version

Gets a Version object that identifies the operating system.

Version​String

Gets the concatenated string representation of the platform identifier, version, and service pack that are currently installed on the operating system.

Methods

Clone()

Creates an OperatingSystem object that is identical to this instance.

Get​Object​Data(​Serialization​Info, ​Streaming​Context)

Populates a SerializationInfo object with the data necessary to deserialize this instance.

To​String()

Converts the value of this OperatingSystem object to its equivalent string representation.
