How Can I Detect the Windows OS Version Using .NET?

Use .NET to detect Windows version

Question:

How to determine the Windows operating system version in a .NET application?

Answer:

To detect the Windows operating system version in .NET, you can use the System.Environment.OSVersion attribute. It provides the following information:

• PlatformID: Indicates the underlying platform (e.g., Win32Windows, Win32NT)
• Major Version: The major version number of Windows (for example, 4 for Windows 95, 6 for Windows Vista, 10 for Windows 10)
• Minor Version: The minor version number of Windows (for example, 0 for Windows 95, 1 for Windows XP)

Specific Windows version and its OSVersion value:

<code>| Windows版本 | PlatformID | 主要版本 | 次要版本 |
|---|---|---|---|
| Windows 95 | Win32Windows | 4 | 0 |
| Windows 98 | Win32Windows | 4 | 10 |
| Windows Me | Win32Windows | 4 | 90 |
| Windows NT 4.0 | Win32NT | 4 | 0 |
| Windows 2000 | Win32NT | 5 | 0 |
| Windows XP | Win32NT | 5 | 1 |
| Windows 2003 | Win32NT | 5 | 2 |
| Windows Vista | Win32NT | 6 | 0 |
| Windows 2008 | Win32NT | 6 | 0 |
| Windows 7 | Win32NT | 6 | 1 |
| Windows 2008 R2 | Win32NT | 6 | 1 |
| Windows 8 | Win32NT | 6 | 2 |
| Windows 8.1 | Win32NT | 6 | 3 |
| Windows 10 | Win32NT | 10 | 0 |</code>

Note:

• For a more complete understanding of the exact Windows version, use a library that provides this information.
• Make sure your executable assembly manifest explicitly declares compatibility with Windows 8.1 and Windows 10.0 to avoid incorrect OSVersion values ​​for these versions.
