在C＃中，如何可靠地删除进程树

在C＃中，我们使用以下代码来终止进程树。 有时它可以工作，有时它不工作，可能与Windows 7和/或64位有关。

它找到给定进程的子进程的方法是调用GetProcesses来获取系统中的所有进程，然后调用NtQueryInformationProcess来找出其父进程是给定进程的每个进程。 它以递归方式执行此操作，以便走树。

在线文档NtQueryInformationProcess应该使用NtQueryInformationProcess 。 相反，有一种叫做EnumProcesses东西，但我找不到C＃中的任何例子，只有其他语言。

什么是在C＃中杀死进程树的可靠方法？

  public static void TerminateProcessTree(Process process) { IntPtr processHandle = process.Handle; uint processId = (uint)process.Id; // Retrieve all processes on the system Process[] processes = Process.GetProcesses(); foreach (Process proc in processes) { // Get some basic information about the process PROCESS_BASIC_INFORMATION procInfo = new PROCESS_BASIC_INFORMATION(); try { uint bytesWritten; Win32Api.NtQueryInformationProcess(proc.Handle, 0, ref procInfo, (uint)Marshal.SizeOf(procInfo), out bytesWritten); // == 0 is OK // Is it a child process of the process we're trying to terminate? if (procInfo.InheritedFromUniqueProcessId == processId) { // Terminate the child process (and its child processes) // by calling this method recursively TerminateProcessTree(proc); } } catch (Exception /* ex */) { // Ignore, most likely 'Access Denied' } } // Finally, terminate the process itself: if (!process.HasExited) { try { process.Kill(); } catch { } } }

使用ManagmentObjectSearcher和一点递归：

 private static void KillProcessAndChildren(int pid) { ManagementObjectSearcher searcher = new ManagementObjectSearcher ("Select * From Win32_Process Where ParentProcessID=" + pid); ManagementObjectCollection moc = searcher.Get(); foreach (ManagementObject mo in moc) { KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"])); } try { Process proc = Process.GetProcessById(pid); proc.Kill(); } catch (ArgumentException) { // Process already exited. } }
