windows 8 启动自动加载VHD存储池

当对多个磁盘做了存储池后，使用diskpart命令批量加载非常缓慢，可以使用下面代码非常高效，在c盘根目录创建vhdlist.txt用来保存多个vhd文件的路径：

 

using System;
using System.Globalization;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Text;
using System.IO;

namespace VhdAttachSample {
   
    static class Program {

        [STAThread]
        static void Main()
        {

            string[] temp = System.IO.File.ReadAllLines("c:\\vhdList.txt", System.Text.Encoding.UTF8);

            foreach (string path in temp)
            {
                
                               
                string fileName = @path;

                IntPtr handle = IntPtr.Zero;

                // open disk handle
                var openParameters = new OPEN_VIRTUAL_DISK_PARAMETERS();
                openParameters.Version = OPEN_VIRTUAL_DISK_VERSION.OPEN_VIRTUAL_DISK_VERSION_1;
                openParameters.Version1.RWDepth = OPEN_VIRTUAL_DISK_RW_DEPTH_DEFAULT;

                var openStorageType = new VIRTUAL_STORAGE_TYPE();
                openStorageType.DeviceId = VIRTUAL_STORAGE_TYPE_DEVICE_VHD;
                openStorageType.VendorId = VIRTUAL_STORAGE_TYPE_VENDOR_MICROSOFT;

                int openResult = OpenVirtualDisk(ref openStorageType, fileName, VIRTUAL_DISK_ACCESS_MASK.VIRTUAL_DISK_ACCESS_ALL, OPEN_VIRTUAL_DISK_FLAG.OPEN_VIRTUAL_DISK_FLAG_NONE, ref openParameters, ref handle);
                if (openResult != ERROR_SUCCESS)
                {
                    throw new InvalidOperationException(string.Format(CultureInfo.InvariantCulture, "Native error {0}.", openResult));
                }

 

                // attach disk - permanently
                var attachParameters = new ATTACH_VIRTUAL_DISK_PARAMETERS();
                attachParameters.Version = ATTACH_VIRTUAL_DISK_VERSION.ATTACH_VIRTUAL_DISK_VERSION_1;
                int attachResult = AttachVirtualDisk(handle, IntPtr.Zero, ATTACH_VIRTUAL_DISK_FLAG.ATTACH_VIRTUAL_DISK_FLAG_PERMANENT_LIFETIME, 0, ref attachParameters, IntPtr.Zero);
                // if (attachResult != ERROR_SUCCESS) {
                //      throw new InvalidOperationException(string.Format(CultureInfo.InvariantCulture, "Native error {0}.", attachResult));
                //  }

                // close handle to disk
                CloseHandle(handle);

                // System.Windows.Forms.MessageBox.Show("Disk is attached.");
