Csharp检测父进程

Csharp检测父进程

可以用 GetParentProcess获取父进程名称,鼠标双击打开的父进程是explorer。而命令行打开的父进程是cmd.exe

Process Parent = ParentProcessUtilities.GetParentProcess();
Process Grandpa = ParentProcessUtilities.GetParentProcess(Parent.Handle);
if (Grandpa != null || !Parent.ProcessName.ToLower().Contains("explorer"))
        Environment.Exit(0);
[StructLayout(LayoutKind.Sequential)]
    public struct ParentProcessUtilities
    {
        // These members must match PROCESS_BASIC_INFORMATION
        internal IntPtr Reserved1;
        internal IntPtr PebBaseAddress;
        internal IntPtr Reserved2_0;
        internal IntPtr Reserved2_1;
        internal IntPtr UniqueProcessId;
        internal IntPtr InheritedFromUniqueProcessId;

        [DllImport("ntdll.dll")]
        private static extern int NtQueryInformationProcess(IntPtr processHandle, int processInformationClass, ref ParentProcessUtilities processInformation, int processInformationLength, out int returnLength);

        /// <summary>

        /// </summary>

        public static Process GetParentProcess()
        {
            return GetParentProcess(Process.GetCurrentProcess().Handle);
        }

        /// <summary>
        /// Gets the parent process of specified process.

        {
            Process process = Process.GetProcessById(id);
            return GetParentProcess(process.Handle);
        }

        /// <summary>

            ParentProcessUtilities pbi = new ParentProcessUtilities();
            int returnLength;
            int status = NtQueryInformationProcess(handle, 0, ref pbi, Marshal.SizeOf(pbi), out returnLength);
            if (status != 0)
                throw new Win32Exception(status);

            try
            {
                return Process.GetProcessById(pbi.InheritedFromUniqueProcessId.ToInt32());
            }
            catch (ArgumentException)
            {
                // not found
                return null;
            }
        }
        }/
