OperatingSystem Class

Represents information about an operating system, such as the version and platform identifier. This class cannot be inherited.

System.Object
  System.OperatingSystem

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class OperatingSystem : ICloneable, 
	ISerializable

The OperatingSystem type exposes the following members.

  NameDescription
Public methodSupported by the XNA FrameworkOperatingSystemInitializes a new instance of the OperatingSystem class, using the specified platform identifier value and version object.

  NameDescription
Public propertySupported by the XNA FrameworkPlatformGets a System.PlatformID enumeration value that identifies the operating system platform.
Public propertyServicePackGets the service pack version represented by this OperatingSystem object.
Public propertySupported by the XNA FrameworkVersionGets a System.Version object that identifies the operating system.
Public propertyVersionStringGets the concatenated string representation of the platform identifier, version, and service pack that are currently installed on the operating system.

  NameDescription
Public methodSupported by the XNA FrameworkCloneCreates an OperatingSystem object that is identical to this instance.
Public methodSupported by the XNA FrameworkEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodSupported by the XNA FrameworkGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetObjectDataPopulates a System.Runtime.Serialization.SerializationInfo object with the data necessary to deserialize this instance.
Public methodSupported by the XNA FrameworkGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodSupported by the XNA FrameworkToStringConverts the value of this OperatingSystem object to its equivalent string representation. (Overrides Object.ToString().)

The OperatingSystem class contains information about an operating system.

For information about the current runtime operating system, retrieve the OperatingSystem object returned by the 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.

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'
