using System;

    static void Main(string[] args) {
        string processName = "javaw";  // 进程名称，可根据实际情况进行修改

        ManagementObjectSearcher searcher =
                new ManagementObjectSearcher("SELECT CommandLine FROM Win32_Process WHERE Name='" + processName + ".exe'");
        foreach (ManagementObject process in searcher.Get()) {
            string commandLine = process["CommandLine"].ToString();
            Console.WriteLine("Process {0} started with command line: {1}", processName, commandLine);
        }
    }
}
