OperatingSystem Class
Represents information about an operating system, such as the version and platform identifier. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
The OperatingSystem type exposes the following members.
Name | Description | |
---|---|---|
OperatingSystem | Initializes a new instance of the OperatingSystem class, using the specified platform identifier value and version object. |
Name | Description | |
---|---|---|
Platform | Gets a System.PlatformID enumeration value that identifies the operating system platform. | |
ServicePack | Gets the service pack version represented by this OperatingSystem object. | |
Version | Gets a System.Version object that identifies the operating system. | |
VersionString | Gets the concatenated string representation of the platform identifier, version, and service pack that are currently installed on the operating system. |
Name | Description | |
---|---|---|
Clone | Creates an OperatingSystem object that is identical to this instance. | |
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetObjectData | Populates a System.Runtime.Serialization.SerializationInfo object with the data necessary to deserialize this instance. | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ToString | Converts 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.
// Example for the OperatingSystem constructor and the // OperatingSystem.ToString( ) method. using System; class OpSysConstructDemo { // Create and display an OperatingSystem object. static void BuildOSObj( PlatformID pID, Version ver ) { OperatingSystem os = new OperatingSystem( pID, ver ); Console.WriteLine( " {0}", os.ToString( ) ); } static void BuildOperatingSystemObjects( ) { // The Version object does not need to correspond to an // actual OS version. Version verNull = new Version( ); Version verMajMin = new Version( 3, 11 ); Version verMMBld = new Version( 5, 25, 625 ); Version verMMBVer = new Version( 5, 6, 7, 8 ); Version verString = new Version( "3.5.8.13" ); // All PlatformID members are shown here. BuildOSObj( PlatformID.Win32NT, verNull ); BuildOSObj( PlatformID.Win32S, verMajMin ); BuildOSObj( PlatformID.Win32Windows, verMMBld ); BuildOSObj( PlatformID.WinCE, verMMBVer ); BuildOSObj( PlatformID.Win32NT, verString ); } public static void Main( ) { Console.WriteLine( "This example of the OperatingSystem constructor " + "and \nOperatingSystem.ToString( ) " + "generates the following output.\n" ); Console.WriteLine( "Create and display several different " + "OperatingSystem objects:\n" ); BuildOperatingSystemObjects( ); Console.WriteLine( "\nThe OS version of the host computer is:\n\n {0}", Environment.OSVersion.ToString( ) ); } } /* This example of the OperatingSystem constructor and OperatingSystem.ToString( ) generates the following output. Create and display several different OperatingSystem objects: Microsoft Windows NT 0.0 Microsoft Win32S 3.11 Microsoft Windows 98 5.25.625 Microsoft Windows CE 5.6.7.8 Microsoft Windows NT 3.5.8.13 The OS version of the host computer is: Microsoft Windows NT 5.1.2600.0 */
