Description
Describes the current operating system: platform and version.
Use TOSVersion to get information about the current operating system, such as:
- Platform (Windows, MAC OS X, iOS, Android, or Linux)
- Version
Other information:
- Architecture (Intel x86, Intel x64, ARM 32, or ARM 64)
- Installed service pack
Example:
Writeln(TOSVersion.ToString);
Possible output:
Windows XP Service Pack 3 (Version 5.1, Build 2600, 32-bit Edition)
or
Windows 11 (Version 21H2, OS Build 22000.318, 64-bit Edition)
You cannot create TOSVersion variables. TOSVersion represents static (global) data initialized at application start-up.
TOSVersion provides methods to check the version of the operating system. See the overloads of Check.
Note:
On the Linux platform, the output is the Kernel version, not the version of the operating system.
For macOS 11 and later, if the application is built with 10.15 or previous SDK version, the macOS returns 10.16 as a "compatible version number".
