class Program

    static void Main()
    {
        Process[] processes = Process.GetProcesses();

        foreach (Process process in processes)

                string processOwner = GetProcessOwner(process.Id);

            }
            catch (Exception ex)
            {
                Console.WriteLine($"获取进程所有者失败: {ex.Message}");
            }
        }

        Console.ReadLine();
    }

    static string GetProcessOwner(int processId)
    {
        string processOwner = null;

        ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
        ManagementObjectCollection processList = searcher.Get();

        foreach (ManagementObject obj in processList)

        }
