Use the Environment.OSVersion and OperatingSystem.Platform properties to obtain the PlatformID enumeration for the currently executing operating system or development platform. Use the PlatformID enumeration to help determine whether the current operating system or development platform supports your application.
The following example demonstrates using the PlatformID class to identify the currently executing operating system.
' This example demonstrates the PlatformID enumeration. Imports System Class Sample Public Shared Sub Main() Dim msg1 As String = "This is a Windows operating system." Dim msg2 As String = "This is a Unix operating system." Dim msg3 As String = "ERROR: This platform identifier is invalid." ' Assume this example is run on a Windows operating system. Dim os As OperatingSystem = Environment.OSVersion Dim pid As PlatformID = os.Platform Select Case pid Case PlatformID.Win32NT, PlatformID.Win32S, _ PlatformID.Win32Windows, PlatformID.WinCE Console.WriteLine(msg1) Case PlatformID.Unix Console.WriteLine(msg2) Case Else Console.WriteLine(msg3) End Select End Sub 'Main End Class 'Sample ' 'This example produces the following results: ' 'This is a Windows operating system.
