当wm下GetProcesses不好用了，要杀特定的进程就只能通过窗体的标题了：

        public bool KillProcessByWindowsTitle(string title)
        {
            IntPtr hWnd = SafeNativeMethods.FindWindow(null, title);
            if (hWnd != IntPtr.Zero)
            {
                int processId = 0;
                SafeNativeMethods.GetWindowThreadProcessId(hWnd, ref processId);
                IntPtr hProcess = IntPtr.Zero;
                hProcess = SafeNativeMethods.OpenProcess(SafeNativeMethods.PROCESS_ALL_ACCESS, 0, processId);
                if (hProcess != IntPtr.Zero)
                {
                    if (SafeNativeMethods.TerminateProcess(hProcess, 1))
                    {
                        SafeNativeMethods.CloseHandle(hProcess);
                        return true;
                    }
                    else
                    {
                        SafeNativeMethods.CloseHandle(hProcess);
                        return false;
                    }
                }
                else
                {
                    return false;
                }
            }
            return false;
        }
        internal sealed class SafeNativeMethods
        {
            [DllImport("coredll.dll")]
            public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
            public const int PROCESS_ALL_ACCESS = 0x000F0000 | 0x00100000 | 0xFFF;
            [DllImport("coredll.dll")]
            public extern static int GetWindowThreadProcessId(IntPtr hWnd, ref int lpdwProcessId);
            [DllImport("coredll.dll")]
            public extern static IntPtr OpenProcess(int fdwAccess, int fInherit, int IDProcess);
            [DllImport("coredll.dll")]
            public extern static bool TerminateProcess(IntPtr hProcess, int uExitCode);
            [DllImport("coredll.dll")]
            public extern static bool CloseHandle(IntPtr hObject);
        }

 但，也许大部分设备上，GetProcesses是好用的（我比较倾向认为我点儿背。）
