Examples

The following example demonstrates using the Win32S class to identify the currently executing operating system.

// This example demonstrates the PlatformID enumeration.
using namespace System;
int main()
{
   String^ msg1 = L"This is a Windows operating system.";
   String^ msg2 = L"This is a Unix operating system.";
   String^ msg3 = L"ERROR: This platform identifier is invalid.";
   
   // Assume this example is run on a Windows operating system.
   OperatingSystem^ os = Environment::OSVersion;
   PlatformID pid = os->Platform;
   switch ( pid )
   {
      case PlatformID::Win32NT:
      case PlatformID::Win32S:
      case PlatformID::Win32Windows:
      case PlatformID::WinCE:
         Console::WriteLine( msg1 );
         break;

      case PlatformID::Unix:
         Console::WriteLine( msg2 );
         break;

      default:
         Console::WriteLine( msg3 );
         break;
   }
   return 1;

Remarks

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.

You can use the underlying integer value of each PlatformID enumeration member, as shown in the Fields table, as the PlatformId argument for the SignTool.exe (Sign Tool) utility.
