ManagementObjectSearcher在System.Management命名空间中。

public static class ProcessEx

{
/// <summary>
/// 结束进程树
/// </summary>
/// <param name="parent">父进程</param>
public static void KillProcessTree(this Process parent)
{
var searcher = new ManagementObjectSearcher("Select * From Win32_Process Where ParentProcessID=" + parent.Id);
var moc = searcher.Get();
foreach (ManagementObject mo in moc)
{
Process childProcess = Process.GetProcessById(Convert.ToInt32(mo["ProcessID"]));//通过子进程ID获取该进程实例
childProcess.KillProcessTree();//调用拓展方法结束当前进程的所有子进程
}
Console.WriteLine(string.Format("kill process by id {0}!", parent.Id));
//不能结束自己
if(parent.Id != Process.GetCurrentProcess().Id)
parent.Kill();//结束当前进程
}
/// <summary>
/// 结束指定进程和它的进程树（所有子进程）
/// </summary>
/// <param name="pid">进程Id</param>
public static void KillProcessTreeById(int pid)
{
try
{
var process = Process.GetProcessById(pid);//获取当前进程
try

process.KillProcessTree();//结束进程树
}
catch (Exception e)

}

Console.WriteLine("failed to get the process!");
var searcher = new ManagementObjectSearcher("Select * From Win32_Process Where ParentProcessID=" + pid);
var moc = searcher.Get();
foreach (ManagementObject mo in moc)
