MacOSX	6	作業系統是 Macintosh。 這個值是由 Silverlight 傳回。 在 .NET Core 上，替代的值為 Unix。
Other	7	其他作業系統。 這包括瀏覽器 (WASM)。
Unix	4	作業系統是 Unix。
Win32NT	2	作業系統是 Windows NT 或更新版本。
Win32S	0	作業系統是 Win32。 這個值不再使用。
Win32Windows	1	作業系統是 Windows 95 或 Windows 98。 這個值不再使用。
WinCE	3	作業系統是 Windows CE。 這個值不再使用。
Xbox	5	開發平台為 Xbox 360。 這個值不再使用。

範例

下列範例示範如何使用 PlatformID 類別來識別目前正在執行的作業系統：

// 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;
}

/*

*/

// This example demonstrates the PlatformID enumeration.
using System;

{
    public static void Main()
    {
    string msg1 = "This is a Windows operating system.";
    string msg2 = "This is a Unix operating system.";
    string msg3 = "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:

match pid with

| PlatformID.Win32Windows
| PlatformID.WinCE ->
    printfn $"{msg1}"
| PlatformID.Unix ->
    printfn $"{msg2}"
| _ ->
    printfn $"{msg3}"
// This example produces the following results:
//     This is a Windows operating system.

備註

Environment.OSVersion使用 和 OperatingSystem.Platform 屬性來取得 PlatformID 目前執行之作業系統或開發平臺的列舉。 PlatformID使用 列舉來協助判斷目前的作業系統或開發平臺是否支援您的應用程式。

您可以使用每個 PlatformID 列舉成員的基礎整數值作為 PlatformId SignTool.exe (符號工具) 公用程式的引數。
