如何在运行时检查Win32中的Windows版本？

#include<iostream>
#include<Windows.h>

int main() {
    OSVERSIONINFOEX osvi;
    ZeroMemory(&osvi, sizeof(OSVERSIONINFOEX));
    osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFOEX);

    if (GetVersionEx((LPOSVERSIONINFOW)&osvi)) {
        std::cout << "Windows version: " << osvi.dwMajorVersion << "." << osvi.dwMinorVersion<< std::endl;
    } else {
        std::cout << "Error: Unable to determine Windows version."<< std::endl;
    }

    return 0;
}

using System;

namespace GetWindowsVersion {
    class Program {
        static void Main(string[] args) {
            Version osVersion = Environment.OSVersion.Version;
            Console.WriteLine("Windows version: " + osVersion.Major + "." + osVersion.Minor);
        }
    }
}

Windows version: 10.0
