OperatingSystem Class

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


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

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class OperatingSystem _
	Implements ICloneable, ISerializable

The OperatingSystem type exposes the following members.

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

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.

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 example, the Environment.OSVersion property returns information about the currently executing operating system in an OperatingSystem object.

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 you require.

The following code example creates objects of the OperatingSystem class with selected values for the Platform and Version properties.
