OperatingSystem 类
表示有关操作系统的信息，如版本和平台标识符。无法继承此类。
**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

备注
OperatingSystem 类包含有关操作系统的信息。例如，Environment.OSVersion 属性在 OperatingSystem 对象中返回有关当前正在执行的操作系统的信息。
在设计上，OperatingSystem 类不是描述操作系统的一般方式，从 OperatingSystem 类派生的类型无法包含更多内容。如果需要一个类型用于包含有关操作系统的其他信息，则应创建自己的类型，然后包括一个 OperatingSystem 类型的字段，以及所需的任何其他字段、属性或方法。
示例
下面的代码示例使用 Platform 和 Version 属性的所选值创建 OperatingSystem 类的对象。
' Example for the OperatingSystem constructor and the
' OperatingSystem.ToString( ) method.
Imports System
Imports Microsoft.VisualBasic
Module OpSysConstructDemo
' Create and display an OperatingSystem object.
Sub BuildOSObj( pID As PlatformID, ver As Version )
Dim os As New OperatingSystem( pID, ver )
Console.WriteLine( " {0}", os.ToString( ) )
End Sub
Sub BuildOperatingSystemObjects( )
' The Version object does not need to correspond to an
' actual OS version.
Dim verNull As New Version( )
Dim verMajMin As New Version( 3, 11 )
Dim verMMBld As New Version( 5, 25, 625 )
Dim verMMBVer As New Version( 5, 6, 7, 8 )
Dim verString As New Version( "3.5.8.13" )
