如何通过id获取进程的命令行参数？

我有一个正在运行的进程的ID（由我不启动）。我怎样才能获得命令行参数？

Answer 1

你可以用wmi来获取这种信息

var q = string.Format("select CommandLine from Win32_Process where ProcessId='{0}'", processId);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(q);
ManagementObjectCollection result = searcher.Get();
foreach (ManagementObject obj in result)
    Console.WriteLine("[{0}]", obj["CommandLine"]);
